Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
Not all tumors are cancerous; benign tumors do not spread to other parts of the body. Possible signs and symptoms include: a new lump, abnormal bleeding, a prolonged cough, unexplained weight loss, and a change in bowel movements, among others.
While these symptoms may indicate cancer, they may also occur due to other issues.There are over 100 different known cancers that affect humans.
