Lung Cancer Treatment in Delhi NCR, India If you have early stage small cell lung cancer you are most likely to have chemotherapy and then radiotherapy to the lung. People who are fairly fit may have chemotherapy and radiotherapy at the same time (chemoradiation). It is quite common for this type of cancer to spread to the brain. So doctors often recommend radiotherapy to the brain for people whose lung cancer shrinks with chemotherapy treatment. It aims to try to kill any cancer cells that may have already spread to the brain but are too small to show up on scans. Doctors call this prophylactic cranial irradiation or PCI. For very early stage small cell lung cancer that has not spread to the lymph nodes in the centre of the chest (the mediastinal lymph nodes), you may have surgery to remove the part of the lung containing the tumour (a lobectomy). The surgery is followed by chemotherapy and sometimes radiotherapy. But usually the cancer has already spread at the time of diagnosis and surgery is not then possible. If you have small cell cancer that has spread to lymph nodes or other areas of the body you may have chemotherapy, radiotherapy or treatment to relieve symptoms. If chemotherapy works well to shrink the lung tumour down and you are fairly fit you may also have radiotherapy to the brain to kill any cancer cells that may have already spread there.
