The tendency to develop some types of cancer is believed to be inherited — that is, the genes you were born with might carry a predisposition for cancer.

Why are some cancers more common?

Tobacco use is the most important risk factor for cancer and is responsible for approximately 22% of cancer deaths (2). Cancer causing infections, such as hepatitis and human papilloma virus (HPV), are responsible for up to 25% of cancer cases in low- and middle-income countries (3).

Is cancer a virus?

Strictly speaking, cancer is not contagious. But a fair number of cancers are clearly caused by viral or bacterial infections: lymphomas can be triggered by the Epstein-Barr virus, which also causes mononucleosis. Liver cancers can be caused by Hepatitis B and C.
