Cancer begins in cells that are the building blocks of the body. Normally, the body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even if you do not need, and old cells do not die when they should. These extra cells can have a mass called a tumor. Tumors can be benign or malignant. Benign tumors are not cancer while malignant ones are. Cells from malignant tumors can affect nearby tissues. They can also break and spread to other parts of the body.
Most cancers are, where to start named. For example, lung cancer starts in the lung and breast cancer starts in the chest. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the type of cancer and how advanced it is. Treatment plans can be surgery, radiation and / or chemotherapy.
