Cancer occurs when some normal cells in the body transform into abnormal or malignant cells.
These malignant cells no longer self-regulate their growth. Instead, theses malignant cells proliferate and grow into adjacent tissue. It is difficult for the body s immune system to identify the cancer cells as something unwanted since these cells originated as normal cells. The mainstays of treatment for cancer are surgery, radiation therapy, and chemotherapy. The aim of surgery is, of course, to physically remove the cancer and any local metastasis of the cancer.
