|What is Lung Cancer Treatment?|
Lung cancer is the cells in lungs start to grow in an uncontrolled way and form tumor. Tumors are lumps of tissue made up of abnormal cells. Besides interfering with how the lung functions, cancer cells can spread from the tumor into bloodstream or lymphatic system where they can spread to other organ. The treatment of lung cancer depends on the type of lung cancer and its stage. People with lung cancer may have surgery, chemotherapy, radiation therapy, targeted therapy or a combination treatment.
Surgery for lung cancer removes the tissue that contains the tumor. The surgeon can remove part of the lung or the entire lung. Other than that, removal of a small part of the lung is a wedge resection, removal of a lobe of the lung is a lobectomy and a pneumonectomy is removal of the entire lung. Nearby lymph nodes also removed. Operation may be done by open surgery where the surgeon will make a large cut in your chest or video-assisted thoracic surgery. This is when the surgeon makes a small cut in your chest and uses a camera to guide the operation. If you have stage 1 or 2 non-small cell lung cancer, surgery may be the best option for you. You will not be given chemotherapy before surgery unless have chosen to take part in a clinical trial.
- Radiation Therapy
Radiation Therapy uses high energy rays to kill cancer cells. It affects cells in the treated area. External radiation is the most common type of radiation therapy for lung cancer. Treatments are usually 5 days a week for several weeks. Besides that, the side affect for radiation is depend on the type of radiation therapy, the dose of radiation, and the part of your body that is treated.
Chemotherapy is given in cycles. It uses drugs to kill cancer cells. The drugs then enter the bloodstream and can affect cancer cells all over the body. At this time, the patient is in a rest period after each treatment period. If you have limited small cell lung cancer, chemotherapy is the most important treatment and should be given to you radiotherapy. Besides, if you have stage 3B or 4 non-small cell lung cancer, chemotherapy may be considered with a medicine containing platinum. The side effects depend mainly on which drugs are given and how much. Other than that, the drugs can harm normal cells that divide rapidly.
- Targeted Therapy
Targeted Therapy is one of the treatment uses drugs to block the growth and spread of cancer cells. These drugs target, or alter, a specific molecule or pathway needed for the cancer cells growth Some patient with non-small cell lung cancer that has spread receive a targeted therapy.
