Causes and Symptoms of cervical cancer

March 11th, 2010

Studies have found a number of factors that may increase the risk of cervical cancer.
- HPV infection: HPV is a group of viruses that can infect the cervix. An HPV infection that doesn’t go away can cause cervical cancer in some women. HPV is the cause of nearly all cervical cancers. A vaccine for females ages 9 to 26 protects against two types of HPV infection that cause cervical cancer.
- Smoking: Among women who are infected with HPV, smoking cigarettes slightly increases the risk of cervical cancer.
- Weakened immune system.
- Sexual history: Women who have had many sexual partners have a higher risk of developing cervical cancer or vice versa.
- Irregular screening tests: Women who have not regularly had a Pap test (smear) are at increased risk of cervical cancer. In particular, many women over age 60 have not had regular Pap tests and are at increased risk.

Symptoms of Cervical Cancer

Early cervix cancer generally produces no signs or symptoms. But, as the cancer grows, symptoms may include :
- Abnormal bleeding.
- Unusual heavy discharge : It may be foul smelling, watery, thick, or contain mucus. It varies from woman to woman.
- Bleeding after sexual intercourse, douching, or a pelvic exam.
- Menstrual periods that last longer and are heavier than before.
- Pelvic pain and pain during sex.
- Pain during urination.
- Bleeding between regular menstrual periods.

Breast Cancer – causes and symptoms

March 3rd, 2010

Abnormal development of cells leads to the growth of tumor, when tumor is malignant in nature they are termed as cancer. The term “breast cancer” refers to a malignant tumor that has developed from cells in the breast. Usually breast cancer either begins in the cells of the lobules, which are the milk-producing glands, or the ducts, the passages that drain milk from the lobules to the nipple. Over time, cancer cells can invade nearby healthy breast tissue and make their way into the underarm lymph nodes, small organs that filter out foreign substances in the body.

Causes of Breast Cancer

The exact cause of breast cancer is not known but some causes associated with breast cancer are :
- Age : As the person gets older, chances of having breast cancer increases.
- Family history : Any close relative diagnosed with breast cancer increases the risk factor.
- Early start onset of menses and early menopause are also associated with breast cancer.
- Exposure to chemicals.
- Exposure to radioactive rays increases the chances of breast cancer.
- Late childbearing increases the risk of breast cancer.

Symptoms of Breast Cancer

Initially, breast cancer may not cause any symptoms. A lump may be too small for you to feel or to cause any unusual changes you can notice on your own.
* swelling of all or part of the breast.
* skin irritation or dimpling.
* breast pain.
* nipple pain or the nipple turning inward.
* redness, scaliness, or thickening of the nipple or breast skin.
* a nipple discharge other than breast milk.
* a lump in the underarm area.
These changes also can be signs of less serious conditions that are not cancerous, such as an infection or a cyst. It’s important to get any breast changes checked out promptly by a doctor.

Melanoma – Type of skin cancer

March 2nd, 2010

Melanoma is a disease of the skin in which cancer cells are found in the melanocytes, the cells that produce color in the skin or pigment known as melanin. Melanoma usually occurs in adults, but it may occasionally be found in children and adolescents. Melanoma may also be called cutaneous melanoma or malignant melanoma. Melanoma is the rarest, but most virulent, form of skin cancer.

- A flat or raised growth of black or brown color, often mixed with blue, red, or white parts, from 6 mm to few cm in size, may appear anywhere on the skin, in men mostly on the trunk, in women on the back and legs, and parts of the skin that are usually hidden from the sun, but were exposed to intense sunlight for short periods.
- Melanoma may show one or more of typical ABCDE characteristics: Asymmetry: one part of the tumor differs from other parts; Border of the tumor is irregular; Color: tumor may be of different colors, often several colors are present in one tumor; Diameter above 6 mm (in most cases), Evolving: lesion growths and changes color and appearance with time.

Melanoma Skin Cancer

Melanoma Subtypes :
- Superficially spreading melanoma grows relatively slowly.
- Nodular melanoma grows rapidly – weeks to months. It tends to ulcerate and bleed.
- Acral lentiginous melanoma appears in dark skinned people (Afro-American, Asian, and Hispanic), mostly on their palms, soles, and under nails.
- Lentigo maligna melanoma. A macule grows slowly (years) as a patch, over 1-3 cm in size. It does not spread to other organs.

Treatment :
- Chemotherapy is often used to treat melanoma that has returned or spread.
- Medications such as interferon or interleukin, which boost the immune system to fight the cancer, may be useful in addition to chemotherapy and surgery. This kind of treatment is called immunotherapy. However, interferon has many side effects and can be difficult to tolerate.
- Radiation treatments may be used to relieve pain or discomfort caused by cancer that has spread.
- Cancer that has spread elsewhere in the body is sometimes removed with surgery to relieve pain or discomfort.
