Lung cancer is cancer in some of the cells in any parts of your lungs. it mainly starts in cells lining an organ called carcinoma. I quote; " the tissue that forms the base of the skin and the lining of the body’s inner surfaces"
There are different types of lung caner, the two main/common ones are called small cell carcinomas and non-small cell carcinomas. Lung cancer can vary depending on what cell is affected.
Small cell carcinomas:
Small cell carcinomas are also known as oat cell carcinomas because of it's shape. They are the cause of 15% of Lung Cancers. The cause of this particular Lung cancer is strongly because of cigarette smoking. Sadly, it spreads early and causes symptoms i quote: "so it's often already spread at the time of diagnosis."
Non-small cell carcinomas
Cells are 'building blocks' of our body, humans are made out of millions of cells which make up organs in our body. Different cells are made for different functions and there are many of them.
There is a part called the 'chest cavity' (thorax) found below the neck and shoulders, it is an area enclosed by the ribs. In the lower part there is the diaphragm, a wide, thin, dome of muscle found above the waist. Below that is the abdomen. I quote: "Non-small cell carcinomas include squamous cell carcinoma, adenocarcinoma large cell carcinoma, and bronchiolo-alveolar cell carcinoma." Squamous cell carcinomas usually damage cells that line the bronchi.
Causes of lung cancer.
It is estimated that around 90% of lung cancer is caused. Lung cancer mainly occurs in adults with ages 40-70years who would've probably smoked around 20 years. Some may have even started when they were teenagers.
Passive smoking, which is breathing in someone else's smoke. Eg. If you walk past a smoker or lives with someone who smokes daily in your main environment and breathe in their smoke, can also cause lung cancer and other diseases, as well as children and babies if their parents smoke around them near by.
i quote: "More than 2,300 Victorians are diagnosed with lung cancer each year." Lung cancer is the most common death in Australia for men and 2nd for woman.
