Cancer Treatments:
  
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, determine which treatment or treatments you will receive. Many new treatments, including cancer vaccines and gene therapy, are being studied in clinical trials.  

Current methods of cancer treatment:
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.
