Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.[2][8] Not all tumors are cancerous; benign tumors do not spread to other parts of the body.[8] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss and a change in bowel movements.[1] While these symptoms may indicate cancer, they may have other causes.[1] Over 100 types of cancers affect humans.[8]

Tobacco use is the cause of about 22% of cancer deaths.[2] Another 10% is due to obesity, poor diet, lack of physical activity, and excessive drinking of alcohol.[2][9][10] Other factors include certain infections, exposure to ionizing radiation and environmental pollutants.[3] In the developing world nearly 20% of cancers are due to infections such as hepatitis B, hepatitis C and human papillomavirus infection.
