CANCER CAUSES AND RISKS FACTOR

Most people don't realize that cancer is preventable in many cases. Learning what causes cancer and what the risk factors are is the first step in cancer prevention. Many cancer risk factors can be avoided, thus reducing the likelihood of developing cancer.

What is the risks factor that may caused cancer?

Food. Artificial sweeteners, fluoridated water, heterocyclic amines in cooked meat. According to Dr. Ted Gansler, director of Medical Content for the American Cancer Society, eating excessive amounts of grilled meat or chicken can increase your risk of developing cancer. This is also true for pan-fried meats at high temperatures.
Current research tells us that the well done or charred meats pose the highest risk. The problem that cooking at very high temperatures break down the amino acid, creatine, in meats. When this occurs, chemical is formed, heterocyclic amines (HAs). HAs are carcinogenic and are linked to cancer.

Tobacco. According to the National Cancer Institute, smoking causes 30% of all cancer deaths in the U.S. and is responsible for 87% of cases of lung cancer. Not only does it affect the lungs, it can cause kidney, pancreatic, cervical, and stomach cancers and acute myeloid leukemia. Quitting smoking immediately decreases your risk factor for cancer.

Weight and Physical activity. Exercising at least 30 minutes a day, 5 days a week greatly reduces your cancer risk. Exercise like yoga, aerobics, walking and running are great activities to lower your cancer risk factor. Not only is physical activity important to preventing other diseases, it reduces the chances of becoming obese. Obesity is a major cause for many cancers. Exercising on a regular basis can prevent prostate, colon, breast, endometrial and lung cancer.

Environmental/workplace Factors. The environment you are in can cause cancer.
Exposure to asbestos, a group of minerals found in housing and industrial building materials can cause a variety of medical problems, such as mesothelioma.
Studies have shown that people who are exposed to high amount of benzene are at risk for cancer. Benzene is a chemical found in gasoline, smoking, and pollution.

Genetics. Genetics can play a big role in cancer development. If you have a family history of cancer, such as breast cancer, taking extra precautions is vital. When cancer is genetic, a mutated gene has been passed down. Genetic tests are available for many hereditary cancers. Keep in mind that if you have a family history of cancer, it does not mean you will develop it. You only have a greater chance of developing it.

Unsafe sex. Practicing unsafe sex can increase your risk of developing a virus called HPV. HPV is a group of over 100 viruses, medically known as human papillioma virus. HPV increases your risk factor for cervical, anal, vulvar and vaginal cancer. Further studies are being conducted in HPV's role in the development of other cancers.

Sun Exposure. Skin cancer is caused by exposure to the UV rays of the sun. A sunburn, or a tan is actually the result of cell damage caused by the sun. Skin cancer can be prevented in most cases. Wearing sunscreen when outdoors and staying out of the sun between the hours of 10 a.m. and 2 p.m., when the sun's rays are strongest is your best defense.
