Decades of research has shown that a person’s chances of getting cancer depend not only on a mishmash of their genes and their environment, but also on certain aspects of their lives – most of which they can control. Here is a list of some of the causes of cancer that have affected people the most:
High levels of radiation, like those from radiation therapy and x-rays (repeated exposure), can damage normal cells and increase the risk of developing leukemia, as well as cancers of the breast, thyroid, lung, stomach and other organs. Long-term exposure to chemicals, such as pesticides, uranium, nickel, asbestos, radon and benzene, can increase the risk of cancer.
Practicing unsafe sex can increase your chances of contracting HPV, medically known as Human papillomavirus. Over 170 types of HPV have been identified. HPV is one of the most common STDs and can go undetected as it doesn’t always cause physical symptoms. It also increases your risk factor for cervical, anal, vulva and vaginal cancer.
Exercise reduces the chances of becoming obese. Obesity is a leading cause of many cancers, but it is a preventable one. Exercising on a regular basis can prevent prostate, colon, breast, endometrial and lung cancer.
Many cancers are associated with having a family history of that cancer; breast, ovarian, prostate and colon are some of these cancers. A theory that exists with some scientific support is that certain smokers have a higher risk of smoking-induced lung cancer than others because of their genetic make-up.
High-fat and high-cholesterol diets are proven risk factors for several types of cancer, such as those of the colon, uterus and prostate. Cigarette smoking and regular exposure to tobacco smoke greatly increases the chance of getting lung cancer. Smokers and tobacco chewers are more likely to develop several other types of cancer, like those of the mouth, larynx, esophagus, pancreas, bladder, kidney and cervix, stomach, liver, prostate, colon and rectum. Heavy drinkers face an increased risk of cancers of the mouth, throat, esophagus, larynx and liver. Some studies suggest that even moderate drinking may slightly increase the risk of breast cancer.
