Cancer is a group of more than 100 different diseases, each with their own set of risk factors. The risk of developing cancer increases as we age, so age along with gender, race and personal and family medical history, are risk factors for cancer. Other risk factors are largely related to lifestyle choices, while certain infections, occupational exposures and some environmental factors can also be related to developing cancer.

Risk Factors:

The risk factor for cancer is based on the below mentioned factors.


2.Growing older



5.Ionizing radiation

6.Certain hormones

7.Certain chemicals

8.Some viruses and bacteria


10.Poor diet, lack of physical activity, and overweight

11.Family history of cancer incidence

    Over time, several factors may act together to cause normal cells to become cancerous. When thinking about your risk of getting cancer, these are some things to keep in mind:

1.Not everything causes cancer.

2.Cancer is not caused by an injury, such as a bump or bruise.

3.Cancer is not contagious. Although being infected with certain viruses or bacteria may increase the risk of some types of cancer, no one can "catch" cancer from another person.

4.Having one or more risk factors does not mean that you will get cancer. Most people who have risk factors never develop cancer.

5.Some people are more sensitive than others to the known risk factors.

6.The recent studies show the unsafe sex is also causes the cancer. It is briefly explained below.

    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 papilloma virus.   increases your risk factor for Cervical, anal, Cervical, and vaginal cancer studies are being conducted in HPV's role in the development of other cancers. There is a test available to see if you have contracted HPV. It involves scraping of cervical cells and then the sample is sent to a lab. The lab test can even identify the strain of the virus, also.
