What is Cancer
Each of the cells of the body have a tightly regulated system that controls their growth, maturity, reproduction and eventual death. Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of out-of-control growth of abnormal cells.
The field of oncology has three major areas: medical, surgical, and radiation.
• Medical oncology: focuses on treatment of cancer with chemotherapy, targeted therapy immunotherapy and hormonal therapy.
• Surgical Oncology : focuses on treatment of cancer with surgery
• Radiation Oncology : focuses on treatment of cancer with radiation.
