Oncology or Cancer Treatment In india
Radiation therapy or radiotherapy is therapy using ionizing radiation, as part of cancer treatment to control or kill malignant cells. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.
Chemotherapy is the use of medicines or drugs to treat a disease, such as cancer. Most of the time this treatment is just called chemo. Surgery and radiation therapy remove, kill, or damage cancer cells in a affected area, but chemo can work throughout the whole body.
Gamma Knife® surgery represents a major advance in brain surgery. Its development has enhanced neurosurgical treatments offered to patients with brain tumors by providing a safe, accurate and reliable treatment option. Gamma Knife® enables patients to undergo a non-invasive form of brain surgery without surgical risks, a long hospital stay or subsequent rehabilitation. Gamma Knife® surgery is unique in that no surgical incision is made to expose the inside of the brain, thereby reducing the risk of surgical complications and eliminating the side effects and dangers of general anesthesia. The "blades" of the Gamma Knife® are the beams of gamma radiation programmed to target the lesion at the point where they intersect. In a single treatment session, 201 beams of gamma radiation focus precisely on the lesion. Over time, most lesions slowly decrease in size and dissolve. The exposure is brief and only the tissue being treated receives a significant radiation dose, while the surrounding tissue remains unharmed. With the Gamma Knife®, a surgical incision is not required; the attendant risks of open neurosurgical procedures (hemorrhage, infection, cerebrospinal fluid leakage, etc.) are therefore avoided.
