Genetic alterations that induce unchecked cell growth and tumor formation are the root cause of cancer. The fundamental causes of sporadic tumors are genomic instability and DNA damage. Genetic mutations that are inherited cause a small percentage of malignancies. The majority of malignancies are caused by environmental, behavioral, or lifestyle exposures.

Various lifestyle choices that may increase your risk of developing some adult malignancies include smoking, eating a lot of fat, and working with hazardous chemicals. However, most cancer patients are too young to have had prolonged exposure to these lifestyle risks.
