Question

what is cancer ? and how many types of cancer .

​

Answer 1

Answer:

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.

There are more than 100 types of cancer, and some are more common than others, depending on things like your age, gender, and racial or ethnic group. (For example, prostate cancer only affects men, and breast cancer is far more likely in women.)
