Lung cancer is a type of cancer that develops from epithelial cells. It begins with an uncontrollable growth of abnormal cells in the tissue that line the inner or outer surface of the lung tissues. The abnormal cells start to divide rapidly to form a lump which is known as a tumor. As tumors become more numerous and larger, they weaken the ability of the lungs to provide oxygen to the bloodstreams. A tumor can either be benign or malignant, benign tumor remains in one place and does not appear to spread at all. However, it can cause illness in various parts of the body while, malignant tumor spreads to the other part of the body through the bloodstreams. Once a tumor is developed in the blood vessels, its cells …show more content…
Short-term effects are generally unpleasant and may give a headache, sore throat, cough or may even cause dizziness. Long-term effects lead to the development of chronic obstructive pulmonary disease, which causes breathing difficulties. Children that are being exposed to tobacco smoke are likely to encounter a number of serious conditions such as asthma, middle ear infections, bronchitis and pneumonia because tobacco smoke contains a large amount of harmful and addictive chemicals. (6) Passive smoke can be reduced by making homes free of smoke, not allowing smoke in any enclosed place where non-smokers spend time, stopping children from going to places where people smoke and also making sure cars are always smoke-free. …show more content…
THE GRAPH BELOW SHOWS HOW THE RATE OF SURVIVAL HAS GRADULLY FALLEN BEYOND FIVE YEARS OF DIAGNOSIS. GIVEN THAT MEN HAVE 30% OF SURVIVAL RATE FOR ONE YEAR, AND THIS PREDICTION FELL TO 8% OF SURVIVAL IN FIVE YEARS AND LOWER IN 10 YEARS. SURVIVAL FOR WOMEN IS SLIGHTLY HIGHER WITH 35% FOR ONE YEAR,12% IN FIVE YEARS AND 7% IN TEN YEARS.

Lung cancer is treated depending on its type, the treatment of non-small cell lung cancer is different from that of small cell lung cancer. Small cell lung cancer is mostly treated with chemotherapy. Non-small cell lung cancer is treated with surgery, biological therapies, chemotherapy, radiotherapy or even a combination of all, depending on the stage of cancer. However, an experiment was carried out on 16th may 2015 which a combination of stem cells and gene therapy could increase the rate of survival for lung cancer.
