Lung cancer stages are when a doctor learns the extent of the disease if a diagnosis is found to be lung cancer. Lung cancer therapy would vary depending on how fast the cancer cells are spreading and how big the tumor is. Staging is performed to find out if the cancer has spread as well as, in that case, to what parts of the body. Cancer of the lung is famous for spreading to the brain or bones, as well as learning how far it has advanced will help the doctor organize the best advantageous treatment. A few exams used to determine whether the cancer has spread include CAT (or CT) scan, MRI, bone scan, mediastinoscopy/mediastinotomy.
Small Cell Lung Cancer
Limited, extensive, or recurrent are the three stages for small cell lung cancer.
Limited Stage: The cancer is present in the nearby lymph nodes and in the lung. The following treatments could be employed : Chemotherapy as well as radiation therapy to the upper body/chest, chemotherapy with or without prophylactic cranial irradiation, a surgical procedure with chemotherapy with or without prophylactic cranial irradiation, medical tests testing new drugs and also new treatment options.
Extensive Stage: Cancer has spread away from the lung to other tissues and organs in the chest and other parts of the body. Treatment method generally is one of the following: Chemotherapy and radiation therapy to the upper body/chest, radiation therapy to areas in the body in which the cancer has spread, medical tests testing new drugs and new treatments.
Recurrent Stage:A cancer that has returned appearing in the lungs or in another part of the body. Cure for reoccurrence can include be one of the following: Radiation treatment, chemotherapy, laser remedy, radiation therapy or even surgical implant of devices to be able to keep the airways open, medical trial testing of new drugs.
Non-Small Cell Lung Cancer:
Non-small cell lung cancer works with a standard staging system. Non-small cell lung cancer tumors may have many stages because they develop slower than small cell lung cancer.
Occult Stage:No tumor can be detected in the lung at this stage but cancer cells are found in the sputum. Lung cancer found at this early on is frequently treated by surgical procedures.
Stage 0: The cancer could be found in just a local area of the lung where only few cancerous cells present. Remedy may well be surgery or photodynamic therapy, as it has not yet grown through the top lining of the lung.
Stage I: Cancer is found only in the lung and is surrounded by normal tissue. Treatment might consist of one of the following: Surgical treatments, radiation therapy, clinical trials of chemotherapy, clinical trials of chemo-prevention, clinical trials of photodynamic therapy.
Stage II: Cancer has increased to include the nearby lymph nodes. Therapy may consist of: A surgical procedure to remove the tumor and lymph nodes, radiation therapy, surgical procedures and/or radiation therapy with or without chemotherapy.
Stage 3A: The cancer has already spread to the chest wall or diaphragm from the lung. It could have spread to the lymph nodes isolating both lungs or in the lymph nodes opposed to this of the chest or in the neck. Remedy for stage IIIA are treated with surgery, but will often incorporate the following: Surgical procedures, chemotherapy as well as other treatment options, surgical procedures and radiation cure, radiation cure alone, laser therapy and/or internal radiation cure.
Stage 3B: Cancer cells have spread into the wall of the chest and probably in the diaphragm nearby the lung. It may also have spread to the lymph nodes in the area separating the two lungs and to the lymph nodes on the other side of the chest or in the neck. Stage IIIB cancer is commonly inoperable. Treatment method may be one of the following: Radiation treatment method alone, chemotherapy plus radiation treatment method, chemotherapy plus radiation treatment followed by surgical procedures, chemotherapy alone.
Stage 4: Cancer cells have already spread to other body parts. Remedy often includes the following: Radiation remedy, chemotherapy, chemotherapy and radiation remedy, laser therapy and/or internal radiation remedy.
Recurrent: Cancer has returned after previous therapy. Cure can include the following: Radiation therapy to control symptoms from the cancer, chemotherapy, chemotherapy with radiation cure, surgery treatment to remove the tumor, laser therapy or internal radiation remedy, radio-surgery.
A brief guide for non-small cell lung cancer survival by stage based primarily on a 5-year survival rate: Stage 1 is 47%, Stage II is 26%, Stage III is 8%, and Stage IV is 2%. All these 5-year rates are generally based mostly on patients diagnosed and originally taken care of greater than 5yrs ago, so the survival rate at present will be much more guaranteeing. – lung cancer stages
