Transcript of Lung cancer
what is lung cancer
what are the cause of lung cancer
About 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke. Smoking is clearly the strongest risk factor for lung cancer, but it often interacts with other factors. Smokers exposed to other known risk factors such as radon and asbestos are at even higher risk.
the signs and symptoms of lung cancer
the signs and symptoms of lung cancer are
. A cough that does not go away or gets worse.
. Coughing up blood or rust-colored sputum (spit or phlegm)
. Chest pain that is often worse with deep breathing, coughing, or laughing.
. Weight loss and loss of appetite.
Shortness of breath.
Feeling tired or weak.
how lung cancer is diagnosed
A CT scan can reveal small lesions in your lungs that might not be detected on an X-ray. Sputum cytology. If you have a cough and are producing sputum, looking at the sputum under the microscope can sometimes reveal the presence of lung cancer cells
treatment for lung cancer
Small cell lung cancer is mostly treated with chemotherapy. Surgery is not usually suitable because this type of cancer has normally spread at the time of diagnosis. You may also have radiotherapy. Non small cell lung cancer can be treated with surgery, chemotherapy, radiotherapy or a combination of these.
