Causes and Risk Factors for CancerMost people do not realize that cancer can be prevented in many cases. Learning what causes cancer and what the risk factors is the first step in preventing cancer. Many factors that increase the risk of cancer can be avoided, so reducing the likelihood of developing cancer. What are the causes and risk factors for cancer:

1. 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 affect the lungs, can cause renal, pancreatic, cervical, and stomach cancer and acute myeloid leukemia. Stop smoking immediately reduces your risk factor for cancer.

2. Exercise

Exercising at least 30 minutes per day, 5 days a week significantly reduces your risk of cancer. Exercises such as yoga, aerobics, walking and running are great activities to lower your cancer risk factor. Not only physical activity is important for preventing other diseases, reduces the risk of obese. Obesity is a major cause for many types of cancer. Exercising regularly can prevent prostate, colon, breast, endometrial and lung cancer.

3. Genetics

Genetics can play a major role in the development of cancer. If you have a family history of cancer, such as breast cancer, taking extra precautions is vital. When cancer is genetic, a mutated gene is passed. Genetic tests are available for many hereditary forms of cancer. Please note that if you have a family history of cancer, does not mean you will develop. You have just one more chance to develop it.

4. Environmental Factors

The environment you are in can cause cancer. Exposure to asbestos, a group of minerals found in homes and industrial building materials can cause a variety of medical problems, such as mesothelioma. Studies have shown that people exposed to high amounts of benzene are cancer risk. Benzene is a chemical found in gasoline, smoke, and pollution.

5. Unsafe sex

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

There is a test available to see if you have sustained HPV. It involves scraping of cervical cells and then the sample to a laboratory. The lab test can even identify the strain of the virus, too.

6. Sun exposure

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