- A lot of research has been made in cancer, but we still do not understand exactly what causes most cancers. There are certain known risk factors which are known to be involved in the causation of cancers.
- Different kinds of cancer have different risk factors
- The important risk factors, which are more likely to affect personal cancer risk are
3.Lack of physical activity.
Tobacco use: Cancers of the lung, mouth, voice box, bladder, kidney, cervix, food pipe, and pancreas are related to tobacco use. Smoking alone causes one-third of all cancer deaths. The risk of having lung cancer and other smoking-related cancers is related to total lifetime exposure to cigarette smoke. There is no way to accurately calculate a person’s risk of getting cancer, but the more a person smokes and the longer he or she does it, the greater the risk.
Diet and physical activity: Unhealthy diet and lack of physical activities predispose to obesity. Being overweight or obese is linked with an increased risk of cancers of the breast (among postmenopausal women), bowel, uterus, food pipe, kidney, and possibly other sites as well.
Other risk factors: Other risk factors include environmental factors, infectious diseases, chemicals, radiation and alcohol consumption. Certain cancers like breast are familial, meaning women with a mother or sister who have had breast cancer are more likely to develop the disease themselves.
