Surgery in oncology treatment means the removal of cancer affected parts from the body. This is mainly done by specialist oncologists using regional or general anesthesia. Surgeries can be open or minimally invasive. Other types of cancer surgery that do not involve cuts or wounds include the following:
In this surgery, supercooled liquid nitrogen or argon gas is applied to destroy cancer tissues. This is applicable for treating initial stage skin cancer, precancerous growths in the cervix or skin and retinoblastoma.
Powerful laser beams are used to remove the specific tissue especially the inner linings of the organs. Because of the highly focused nature of the laser beam, the surgery can be very precise without affecting other areas. It is also applied to destroy or shrink tumors that may turn cancerous. Laser surgery is applied to treat cervical, esophageal, vaginal and non-small cell lung cancer.
