A common relationship between genetics and cancer is hereditary cancer. This is when a parent gives their child a gene that increases their chances of getting cancer. This doesn't mean they will ever get it but it does mate it much more likely. Whether you get it or not also depends on things like, family history, your diet, exposure to certain viruses and exposure to some chemicals.

The most common types of hereditary cancer people get are, breast cancer, ovarian cancer, prostate cancer and colorectal cancer. Five to ten percent of all diagnosed cancer is in some way from being passed down through genetics.

If you get cancer and its not because of genes passed down from your parents its because your body has been exposed to things that your body trys to repair and along the way the genes get mutated causing them to multiply rapidly and grow into tumors. Tumors can be removed and radiation applied to the mutated area to try to kill the cancer but there is never a guarantee that it wont come back or that the treatment will even be able to kill the cancer. Sometimes people can get cancer that isn't actually going to do them any harm either. This is called benign and wont do you any harm. Then there is malignant cancer which is the one that can kill you and either one can be hereditary.
