What are some of the risk factors of cancer and bone cancer?

These cancers occur more frequently in children and young adults.
– Those who have had radiation or chemotherapy treatments for other conditions are majorly prone.
– Adults with Paget’s disease, a noncancerous condition characterized by abnormal development of new bone cells, will be at an increased risk for osteosarcoma.
– Children with hereditary retinoblastoma (an uncommon cancer of the eye) are at a higher risk of developing osteosarcoma.
– Many of these risk factors can be avoided.
– Others, such as family history, cannot be avoided.
– People can help protect themselves by staying away from known risk factors.

Cancer risk factors
– Growing older
– Tobacco
– Sunlight
– Ionizing radiation
– Certain chemicals and other substances
– Some viruses and bacteria
– Certain hormones
– Family history of cancer
– Alcohol
– Poor diet, lack of physical activity, or being overweight

Growing older
– The most important risk factor for cancer is growing older.
– Most cancers occur in people over the age of 65.

– Tobacco use is the most preventable cause of death.
– Using tobacco products or regularly being around tobacco smoke increases the risk of cancer.
– They also are more likely to develop acute myeloid leukemia (cancer that starts in blood cells).
Smokers develop cancer of the
– lung,
– larynx (voice box),
– mouth,
– esophagus,
– bladder,
– kidney,
– throat,
– stomach,
– pancreas,
– cervix

– Ultraviolet (UV) radiation comes from the sun, sunlamps, and tanning booths which causes early aging of the skin.
– Skin damage can lead to skin cancer.

Ionizing radiation
– Ionizing radiation can cause cell damage that leads to cancer.
This kind of radiation comes from rays
– that enter the Earth’s atmosphere from outer space,
– radioactive fallout,
– radon gas,
– x-rays,
– other sources
People exposed to fallout may have an increased risk of cancer like
– leukemia
– cancers of the thyroid,
– cancer of breast
– cancer of lung,
– Stomach cancer.

Medical procedures are a common source of radiation:
– Doctors use radiation (low-dose x-rays) to take pictures of the inside of the body.
– Doctors use radiation therapy.

Certain chemicals and other substances
– Jobs of painters, construction workers, and those in the chemical industry have an increased risk of cancer.
– Exposure to asbestos, benzene, benzidine, cadmium, nickel, or vinyl chloride in the workplace can cause cancer.

Some viruses and bacteria
Being infected with certain viruses or bacteria may increase the risk of developing cancer:
– Human papillomaviruses (HPVs): HPV infection is the main cause of cervical cancer.
– Hepatitis B and hepatitis C viruses: Liver cancer can develop after many years of infection with hepatitis B or hepatitis C.
– Human T-cell leukemia/lymphoma virus (HTLV-1): Infection with HTLV-1 increases a person’s risk of lymphoma and leukemia.
– Human immunodeficiency virus (HIV): HIV is the virus that causes AIDS. People who have HIV infection are at greater risk of cancer, such as lymphoma and a rare cancer called Kaposi’s sarcoma.
– Epstein-Barr virus (EBV): Infection with EBV has been linked to an increased risk of lymphoma.
– Human herpesvirus 8 (HHV8): This virus is a risk factor for Kaposi’s sarcoma.
– Helicobacter pylori: This bacterium can cause stomach ulcers. It also can cause stomach cancer and lymphoma in the stomach lining.

Certain hormones
Estrogen alone or estrogen along with progestin hormones may increase the risk of breast cancer, heart attack, stroke, or blood clots.

Alcohol and Poor Diet
It can lead to developing of cancers of the mouth, throat, esophagus, larynx, liver, and breast.
Poor diet, lack of physical activity, or being overweight increases the risk of cancers of the colon, uterus, and prostate.
