Rarer forms of liver cancer include:
- Mesenchymal tissue
- Sarcoma
- Hepatoblastoma
- Cholangiocarcinoma (bile duct cancers)
- Angiosarcoma and hemangiosarcoma
- Lymphoma of liver

Signs and Symptoms of Liver Cancer
- Abdominal mass
- Abdominal pain
- Jaundice
- Nausea
- Liver dysfunction

What are liver cancer symptoms and signs?
- The initial symptoms are not known as these cancers are mostly recognized only at advanced stages.
- Abdominal pain is uncommon with liver cancer
- It usually signifies a very large tumor or widespread involvement of the liver.
- Unexplained weight loss.
- Unexplained fevers.
- The sudden appearance of ascites (abdominal fluid and swelling).
- Jaundice (yellow color of the skin)
- Muscle wasting without causative (precipitating) factors (for example, alcohol consumption).
- Block in the portal vein (a large vein that brings blood to the liver from the intestine and spleen).
- The blood will travel paths of less resistance, such as through esophageal veins which leads to increased pressure in these veins.
- Dilated (widened) veins called esophageal varices occur.
- The patient then is at risk for hemorrhage from the rupture of the varices into the gastrointestinal tract.
- Turbulent blood flow in the artery.
- The turbulence results in a distinct sound in the liver (hepatic bruit).
- Muscle wasting.
- Very swollen liver and massive formation of ascites.
- In some patients, as previously mentioned, the tumor can invade the portal vein and lead to the rupture of esophageal varices.

Symptoms of Cholangiocarcinoma
- Sweating
- Jaundice
- Abdominal pain
- Weight loss
- Hepatomegaly

Symptoms of Hepatocellular carcinoma
- Abdominal mass
- Abdominal pain
- Emesis
- Anemia
- Back pain
- Jaundice
- Itching
- Weight loss
- Fever

What is Brain Tumor?
Brain tumors can either originate from within the brain (“primary brain tumors”). From cancer cells that have metastasized from other organs or tissues (“secondary brain tumors”). Primary brain tumors can be derived from the over twenty different cell types that make up the brain and its linings.

What are Primary Brain Tumor?
Primary tumors can be cancerous (malignant) or benign. These tumours start in the brain and do not spread. They rarely spread beyond the central nervous system. The tumor is still taking up space in the skull. They can cause serious complications and symptoms.

Primary Brain Tumor Types in Adults

- Gliomas
Tumors derived from astrocytes:
- Anaplastic astrocytoma (“grade III”)
- Glioblastoma multiforme
Tumors derived from oligodendrocytes:
- Oligodendrocytes
- Oligodendrogliomas
Tumors derived from ependymal cells:
- Ependymomas
- Anaplastic ependymomas
Meningiomas
- Consequences of intracranial hypertension.
- Dysfunction Irritation.

What are Secondary Brain Tumor?
- These tumours are often called metastatic tumors.
- They are the result of cancer cells originating from another part of the body.
- They are spread to the brain.
- Secondary brain tumors often indicate advanced stages of disease.
- Both cancerous primary and secondary tumors are life threatening.
- These types of tumors are usually very aggressive.
- Secondary tumors means a cancerous neoplasm that has developed in another organ elsewhere in the body
- These cancer cells have leaked from that primary tumor and then entered the lymphatic system and blood vessels.
- They then circulate through the bloodstream.
- They are then deposited in the brain.
- These cells continue growing and dividing.
- They become another invasive neoplasm of the primary cancer’s tissue.
- Secondary tumors of the brain are very common in the terminal phases of patients.

Other Types of Growth
1. Low-grade vs. high-grade:
- Low-grade tumors are slow-growing.
- High-grade tumors are fast-growing and aggressive.
- High-grade tumors can invade nearby tissue or spread elsewhere in the body.
- They are also more likely to recur after treatment.
- They are generally associated with a worse outlook.

2. Localized vs. Invasive:
- Localized tumor is confined to one area.
- It is generally easier to remove.
- It’s in an accessible part of the brain.
- An invasive tumor has spread to surrounding areas.
- It is more difficult or impossible to remove completely.

- encapsulated hematomas.
- encapsulated necrotic tissue (from an insect bite, foreign body, or other noxious mechanism).
- keloids.
- granulomas (discrete overgrowths of scar tissue).

Enlargements of normal structures like:
- ureters,
- blood vessels,
- intrahepatic
- extrahepatic biliary ducts
- pulmonary inclusions
- gastrointestinal duplications

Tumours can be primary and secondary.

Primary Tumors

- Primary tumors can be cancerous (malignant) or benign.
- These tumours start in the brian and do not spread.
- They rarely spread beyond the central nervous system.
- The tumor is still taking up space in the skull.
- They can cause serious complications and symptoms.

Benign Brain Tumors
- These are tumors that remain in the part of the brain in which they started.
- They don’t spread into and destroy other areas of the brain.
- They do not spread to other parts of the body.
- A benign tumour can be removed successfully.
- This shall cause no more problem once removed.
- Some benign tumours will regrow slowly.
- These tumours are treated with radiotherapy or further surgery may be needed.

Malignant Primary Brain Tumors
- These are most likely to cause problems by spreading into the normal brain tissue.
- This causes pressure and damage to the surrounding areas of the brain.
- These tumors rarely spread outside the brain to other parts of the body.

Secondary Tumors

- These tumors are often called metastatic tumors.
- They are the result of cancer cells originating from another part of the body.
- They are spread to the brain.
- Secondary brain tumors often indicate advanced stages of disease.
- Both cancerous primary and secondary tumors are life threatening.
- These types of tumors are usually very aggressive.
- Secondary tumors means a cancerous neoplasm that has developed in another organ elsewhere in the body.
- These cancer cells have leaked from that primary tumor and then entered the lymphatic system and blood vessels.
- They then circulate through the bloodstream.
- They are then deposited in the brain.
- These cells continue growing and dividing.
- They become another invasive neoplasm of the primary cancer’s tissue.
- Secondary tumors of the brain are very common in the terminal phases of patients.

The most common types of cancers that bring about secondary tumors of the brain are:
- lung cancer
- breast cancer
- malignant melanoma
- kidney cancer
- colon cancer
- cervical cancer

Signs and Symptoms of secondary tumors:
- In lymph nodes, a common symptom is lymphadenopathy.
- Lungs: cough, hemoptysis and dyspnea (shortness of breath).
- Liver: hepatomegaly (enlarged liver) and jaundice.
- Bones: bone pain, fracture of affected bones.
- Brain: neurological symptoms such as headaches, seizures, and vertigo.
Secondary tumor is occurred by four routes:
- Transcoelomic
- Lymphatic spread
- Haematogenous spread
- Transplantation or implantation

Colorectal cancer is one such disease which highly affects the rectum and the colon. When the cells in the inner lining of the rectum and the colon start multiplying even when there is no need for multiplication, it gives rise to colorectal cancer.

This is caused mainly due to the abnormal growth of the cells in the rectum and the colon. Colorectal cancer can be very dangerous if not treated at the correct time and in the correct manner. It is the third most common death causing cancer in the world.

There are various risk factors which may lead to colorectal cancer in a person. These risk factors include family history of colorectal cancer i.e. hereditary problem, age factor, smoking and many more. Another very common risk factor of the colorectal cancer is the intake of alcohol. You must be wondering how alcohol can affect the rectum and the colon. This article will tell you the reason why alcohol can prove to be dangerous to you colon and the rectum.

Alcohol has both positive as well as negative effect on the cells of the rectum and colon. As a positive effect, alcohol can lead to the death of the cancerous cells which are growing inside the organs but as a negative effect it may stimulate the proliferation of the cancerous cells. Studies have clearly shown that the risk of colorectal cancer in a person increases with the increase in his alcohol drinking habit. More the intake of alcohol more will be the person at the risk of colorectal cancer.

Studies have been made regularly regarding this aspect and they have shown that the people consuming around or more than 30 grams of alcohol per day are at an increased risk of colorectal cancer than those who do not drink at all.

The people who have an intake of more than 45 grams of alcohol per day are at the maximum risk of colorectal cancer. Also it has been proved that about 3.6 % of colorectal cancer cases are due to alcohol intake and the 3.5 % of the deaths due to colorectal cancer have drinkers involved.

In a research done for about 14 years and 7 months it was shown that out of 400 cases of colorectal cancer about half of the people were at the regular intake of alcohol.People who had 41 drinks per week had 95 % chances of suffering from colorectal cancer.

Alcohol is considered to be dangerous because it stimulates the growth of adenoma and as a result promotes colorectal carcinogenesis. It has been shown by various studies and researches that out of all the drinks containing alcohol, beer is the drink which is closely associated with the risk of colorectal cancer whereas wine has the weakest association.

Alcohol tends to alter the metabolism process of the liver compounds like the genotoxic compounds (eg: nitrosamines). This is because the microsomal monooxygenase i.e. the metabolism system of the liver is suppressed by the intake of alcohol and this as a result leads to the growth of colorectal cancer.

The risk of colorectal cancer due to alcohol intake depends on various factors like the amount of alcohol intake per day, the type of alcohol intake etc. On one hand when studies show that beer can increase the risk of colorectal cancer in a person it has also been proved on the other hand that the moderate intake of wine can reduce the risk of colorectal cancer.

In conclusion, it can be said that alcohol is moderately related with the risk of colorectal cancer.

Colorectal Cancer:
Colon and rectum are the organs which form the large intestine. Colorectal cancer affects these two organs. Colorectal cancer also called the bowel cancer and the colorectal blight is the third most dangerous and death causing cancers. It occurs due to the abnormal growth of cancerous cells in the inner lining of the colon or the rectum.

There are various causes of colorectal cancer. The main cause is the age factor. People who are above the age of 50 are more prone to the colorectal cancer. Another major risk factor of the colorectal cancer is the family history of cancer. If a person has a family history of colorectal cancer then he/ she is more prone to colorectal cancer. Other risk factors include diet, inflammatory bowel disease, race or ethnicity, obesity, smoking, alcohol intake etc.

The presence of colorectal cancer can be known by some symptoms which persist in a patient. These symptoms include weight loss, diarrhoea, abdominal pain, constipation, irritable bowel syndrome etc. When these symptoms persist a person should always go for the diagnosis to confirm the presence of colorectal cancer. There are various tests like colonoscopy, fecal occult blood test, digital rectal exam, barium enema x-rays, sigmoidoscopy, etc which can be performed to detect colorectal cancer. Colorectal cancer can be very well treated with the help of treatments like chemotherapy.

Anal Cancer:
Anal cancer is a very dangerous cancer which affects the anus. Studies have shown that about 50000 people suffer from anal cancer every year and around 620 people die because of it. It is a type of squamous cell carcinoma and is said to near the squamocolumnar junction.

The various risk factors of anal cancer include smoking, anal intercourse, age factor, regular swelling or redness occurring in the anus, having sexual intercourse with different sex partners, fistulas (openings present around the anus which are quite abnormal), HPV virus infection etc.

There are some symptoms which indicate the presence of anal cancer. These include bloating of the bowel, change in the bowel habits, lumps present near the anus, bleeding through the anus, itching of the anus, pain in the anus, discharge from the anus, lower back pain in women due to the pressure exerted on the vagina by the tumours, drying up of the vagina etc.

These symptoms may not be necessarily indicating the presence of anal cancer. They may be due to other more dangerous or less dangerous diseases and therefore one needs to get himself diagnosed to confirm the disease. Various tests which can be performed for confirming the presence of anal cancer are anoscopy, anal pap smears, proctoscopy, digital rectal examination, endo-anal or endorectal ultrasound, biopsy, physical examination etc.

With the help of the above mentioned tests one can get to know what and where exactly the cancer is. After the tests are performed a person can go for the treatment of the anal cancer. Treatments of the anal cancer include infrared photo-coagulation, chemotherapy, surgery, radio sensitizers, radiotherapy, etc

Although, colorectal cancer and anal cancer are very different from each other with respect to their risk factors, treatements, tests, etc but they need to be treated as soon as possible so as to prevent death.

There are various risk factors related to the colorectal cancer. These mainly include the age factor, smoking and drinking habits, family history of colorectal cancer, race and gender, obesity and many more.

We know that colorectal cancer is spread worldwide and is very common in almost every country. This article deals with the worldwide distribution of the colorectal cancer. Since the year 1975, the rate of deaths due to colorectal cancer has increased tremendously. From an annual report made for the colorectal cancer it has been seen that the number of men and women suffering from colorectal cancer are almost same with the count of men being approximately 401000 and that of women being 381000. But as seen by the figures the risk of colorectal cancer is more prominent in men than in women.

The threat of colorectal cancer is more in the westernized countries like North America, Australia and New Zealand. The percentage of incident cancer in these countries when combined was found to be 12.6 % in men and 14.1 % in women. In countries like Japan and Miyagi the risk rates of colorectal cancer have grown up to 47 % in women and 92 % in men. Whereas in United State the incidence rate of colorectal have been found to be declining instead of increasing.

An annual study has shown that there have been almost 394000 deaths due to colorectal cancer hence making it the second most common death causing cancers in European countries. But one should remember that this rate is based on the severity of the cancer and progress of the treatment being taken by the colorectal cancer patient. Race also plays a very important role in the growth of colorectal cancer. Studies have shown that Israel people who are born in countries like Europe or United States are at a higher risk of suffering from colorectal cancer. Also African Americans are more prone to colorectal cancer with a percentage of 53 % as compared to other white Americans.

Environment being a major risk factor of colorectal cancer, colorectal cancer is many times referred to as an environmental disease. The environment factor includes components such as social lifestyle, cultural and lifestyle practices. It has been found that approximately 70 % to 80 % of colorectal cancer cases in many countries are due to the environmental factors mentioned above.

The incidence rates per 100000 of colorectal cancer in various countries are as follows:
France- 53.8
Italy- 49.9
United States- 53.48
Czech Republic- 48.23
Canada (Yukon)-48.98
Canada (Nova Scotia)- 47.84
Israel- 46.79
Australia (New South Wales)- 46.92

These statistics have been provided by the International Agency of Research on Cancer (IARC). There are many other countries like Croatia, China, Russia, Netherlands, Belgium, Portugal, Spain, Brazil, Slovakia, Switzerland, Singapore, Denmark etc which are also prone to colorectal cancer and where the incidence rates have been tremendously increasing every year.

Other less colorectal cancer prone countries include India, Colombia, Turkey, Chile, Kuwait, Costa Rice, Malaysia, Peru, Egypt, Pakistan, Zimbabwe, Uganda, Thailand, Oman, Algeria, Bahrain, Ecuador, Peru and Tunisia.

Although colorectal cancer is spread worldwide but it is less common than other cancers like breast cancer.

A simple Breast Self Examination (BSE) can be done to detect any chances of breast problems like lumps or change in appearance. The breast self examination should be done about a week after your periods end. Breast self-exam should be performed on the same day each month.

Breast self examination involves the following steps :
- Use left hand for right breast and right hand for left breast.
- Remove all your clothes and stand in front of mirror.
- Observe the size, shape, color, symmetry and texture of your breasts.
- Observe for any kind of discharge or puckering of the nipple.
- Observe for sores or scaly skin.
- Examine the breasts in four different postures.
- First, both arms folded down.
- Second, both arms over the head and check for any swelling or puckering of the skin.
- Third, both arms on your hips and press firmly to flex your chest muscles.
- Fourth, bent forward to examine each breast for change in outline or dimpling of the skin.
- Lie down, check the entire right breast area with your left hand. Make small circles and follow an up and down pattern with light, medium and firm pressure over the area of the breast.
- Feel the breast surface with second, third and fourth fingers of the hand making circular motions.
- Also, squeeze the nipple for any kind of discharge.
- Repeat the same steps with left breast but with right hand.
- During shower, examine the breast tissue in the underarms.
- Feel for lumps under and along the top of the collar bone.

-

- Getting up too often
Sometimes you get up very often during night. The reason behind this can be multiple like hunger, over filled tummy, insects, stuffy nose, bed wetting, excessive activity, scary movies or a new baby.

- Bed wetting
Toddler or small children sleep too soundly and they do not feel the urge to go to toilet. It is not their fault instead limit the intake of liquids in evening and make sure that the kid goes to the bathroom before going to bed. Consult a pediatrician because sometimes frequent bed wetting can be a urinary tract infection.

- Sleep walking
It is more common in children of age group 3-7 years old. It occurs early in night. Room should be kept safe for sleep wanders. One needs to guide the child back to bed without waking because if you wake the child, it can give the child a shock. This problem runs into families but it can indicate the presence of problem such as sleep apnea.

- Nightmares
Frightening dreams can wake up your child very often. Reassure the child that it is just the dream and she should not worry until she goes back to sleep.

- Night terrors
It is the condition in which the child is not fully awake and not aware of your presence. She screams and she is covered with perspiration and heart beats are increased. The child settles down after 15-20 minutes and then goes back to sleep.

Lack of sleep can cause inattentiveness at school, poor memory skills, inconsistent academic performance, irritability, susceptibility to colds and flu, under eye circles, accidents, use of stimulants as sleep substitutes.

- Polyps
Colorectal blight can come in action after polyps, but this is attenuate and accounts for more than 1% of all colorectal cancers diagnosed in the US anniversary year. It usually happens in individuals with abiding anarchic bowel diseases, such as abiding ulcerative colitis and Crohn’s colitis.
Intestinal polyps are masses of tissue that appear from the abdominal bank and beetle into the lumen (the autogenous amplitude of the intestine). It’s not bright what produces polyps, but they appear to be acquired by both ecology and biogenetic factor. Cigarette smoking, diets that are top in fat and low in fibre, abridgement of exercise, and blubber may all accord to polyp growth.

Most cancers in the colon and rectum are adenocarcinomas. “Adeno” agency “gland,” and colorectal adenocarcinomas appear in aberrant gland beef that anatomy in the close lining of the colon or rectum. About three-quarters of cancers action in the colon and one-quarter in the rectum.

There are added forms of colorectal cancer:
-Sarcomas (tumors that activate in affiliated tissue)
- Lymphomas (tumors that activate in the aqueous system)
- Rare cancers such as carcinoids and gastrointestinal stromal tumors

Polyps and Blight Spread
Polyps abound boring and may at aboriginal be benign. However, because they may become annihilative over time, they should be removed. Once a polyp becomes cancerous, it starts to access the abdominal bank and may advance into adjacent lymph nodes. From there it can access into the aqueous arrangement and advance to areas abroad from the aboriginal site, or “metastasize.” Annihilative colorectal beef can swell access into capillaries and drift via the bloodstream and lot of to the liver. There, the beef may anatomy new tumors.

Types of Polyps
There are three types of polyps:
- Adenomatous polyps (sometimes referred to as adenomas)
- Hyperplastic polyps
- Inflammatory polyps

Adenomatous polyps account for about 10% of all colonic polyps, but there are the greatest chances of them to become cancerous. Fortunately, they abound slowly: an adenomatous polyp just beneath bisected an inch (10 mm) in bore takes 5-10 years to become dangerous. Adenomatous polyps are disconnected into three altered subtypes: bearded (hairy), tubular, and tubulovillous..

Polyps also appear in altered shapes: pedunculated or sessile. Pedunculated polyps accept ample stalks, like mushrooms, and can be calmly removed during a colonoscopy. Sessile polyps accept ample bases and abound collapsed adjoin the bank of the intestine, authoritative their abatement difficult.

The Aqueous System
The aqueous arrangement works in concert with the allowed arrangement and has several functions in the body. The aqueous system:
- Combats invasive adopted bodies like bacteria, viruses, and fungi.
- Drains interstitial aqueous aback into the bloodstream from the tissues.
- Filters lymph.
- Filters the blood.

The aqueous arrangement includes the aqueous vessels, lymph, lymph nodes, spleen, thymus, cartilage marrow, and a few added organs.
- Aqueous argosy anatomy is an array of alongside circulatory system, aberration throughout the tissues of the body.
- Lymph circulates through body tissues picking up fats, bacteria, and other unwanted materials, filtering these substances out through the lymphatic system. Lymph carries ample numbers of lymphocytes (white claret cells).
- Lymph nodes begin in the armpits, on either ancillary of the groin, on either ancillary of the neck, and in the abdomen, pelvis, and chest. Lymph nodes clarify the lymph aqueous as it passes through it and macrophages central the lymph nodes annihilate intruders, such as bacteria.
- The annoyance produces lymphocytes and filters the blood.
- The thymus helps to aftermath white claret cells.
- Cartilage is a type of connective tissue in the body. Cartilage is avascular, meaning that it is not supplied by blood vessels; instead, nutrients diffuse through the matrix. If blight beef breach off a tumor, they generally become trapped in the abutting lymph node.
