Cancer is also called malignancy. It is characterized by an abnormal growth of cells and has different types including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer, and lymphoma. Cancer symptoms vary widely based on the type of cancer but until now the actual cause of cancer is still unknown.
Cancer occurs inside the body parts when cells become abnormal and keep dividing and spreading and starts to form another more cells without control or order, forming a growth or tumor. Malignat tumors are cancer.
Cancer occurs when cell division gets out of control and divides faster than the normal rate. Usually, the timing of cell division is under strict constraint, wherein the involved network of signals that work together to say when a cell can divide, how often it should happen and how errors may be fixed.
Mutations in one or more of the nodes in this network might trigger cancer, be it through exposure to some environmental factor (e.g. tobacco smoke) or because of a genetic predisposition, or it can be both. Usually, several cancer-promoting factors have to add up before a person will eventually develop a malignant growth: with some exceptions, no one risk alone is sufficient.
The treatment for cancer includes chemotherapy, radiation, and surgery.
