Lung Cancer

By: Jacob Henderson


About 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke. So it is an environmental cause. Lung cancer is caused in non-smokers by second hand smoke, exposure to radon, air pollution, and other factors.

Symptoms and Diagnosis

Some symptoms of lung cancer can be: a cough that doesn't go away or gets worse, weight loss and loss of appetite, feeling tired or weak, coughing up blood or rust colored spit, and shortness of breath.

The diagnosis for lung cancer is getting a CT scan, by getting a CT scan it can reveal small lesions that might not be detected on an x-ray. You can also have a doctor look at your sputum, or spit, under a microscope and sometimes it can reveal the presence of lung cancer cells.

Body Region Affected

The part of your body that lung cancer affects is your lungs, when you get lung cancer and the cells form a cancerous tumor in your lungs the cancer cells begin to destroy and damage your lung tissue. Which also means that the tumor could block your airways and make you not be able to breathe.

Current Treatments and Research

Some current treatments for lung cancer are; surgery, chemotherapy, radiation therapy, targeted drug therapy, clinical trials, and palliative care. Also scientists are researching new ways to help lung cancer patients and are finding new ways to hopefully cure it in the future. They say that the best thing right now that shows the most results is clinical trials. Also they say that biopsies can help with identifying the cancer they had and which treatment would've best benefited it.
