Treatment for any cancer depends on the stage of cancer, age of patient, his general condition mainly. But mainly the treatment includes - Surgery. Surgeon removes affected part or sometimes a lobe or entire lung, depending on all the parameters of patient. Types of surgeries are- Wedge resection, Segmental resection, Lobectomy and Pneumonectomy. Doctors may also remove lymph nodes from chest to check for cancer. Doctor may suggest chemo or radiation therapy before surgery in order to shrink the cancer if it is a large. Also the same may be done in case recurrence is suspected. Radiation therapy It is also recommended in whom surgery is not recommended as the first line of treatment.. Chemotherapy Chemo along with adjuvant treatment to surgery also is given to relieve pain and other symptoms in advanced cancer.
