Treatment of Cancer
There are four major types of cancer treatment: surgery, radiation therapy, chemotherapy, and immunotherapy. These therapies can be used either alone or in combination with each other. Location, size and stage of the tumor, as well as your overall health, determines which treatment or treatments you will receive. Many new treatments, including cancer vaccines and gene therapy, are being studied in clinical trials. 

• Surgery is the oldest form of cancer treatment. About 60% of cancer patients will undergo some sort of surgery, either by itself or in combination with other therapies.
• Chemotherapy uses powerful drugs to kill cancer cells, control their growth, or to relieve pain symptoms.
• Radiation uses large doses of high-energy beams or particles to destroy cancer cells in a specifically targeted area.
• Immunotherapy, also known as biologic therapy, stimulates the body's own defense systems to fight cancer. 
• Gene Therapy identifies missing or defective genes that cause cancer or increase cancer risk, and replaces them with normal copies.
• Clinical Trials in which new treatment methods are tested on human subjects, can provide options for patients whose cancer has not responded to standard therapies.
