Lung cancer was chosen since majority of lung cancers is caused by cigarette smoke which contains harmful chemicals that can cause gene mutations which lead to cancer. Smoking causes the majority of lung cancers — both in smokers and in people exposed to second-hand smoke. But lung cancer also occurs in people who never smoked. Smoking causes lung cancer by damaging the cells that line the lungs. When you inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), this causes changes in the lung tissue to begin almost immediately. At first your body may be able to repair this damage, but with each repeated exposure, normal cells that line your lungs are increasingly damaged. Over time, the damage causes cells to reproduce abnormally and eventually cancer may develop. The cancerous cells can quickly grow into large tumors that can rapidly spread to the brain, liver, bones, and other parts of the body. Some monoclonal antibodies trigger the immune system to attack and kill cancer cells. Although cancer cells are abnormal, they develop from normal cells so they can be difficult for the immune system to spot so monoclonal antibodies simply attach themselves to cancer cells, making them easier for the cells of the immune system to find them.

Majority of people eat chicken eggs but what most people do not know is that duck eggs are superior to chicken eggs. Duck eggs have twice the nutritional value of a chicken egg and stay fresh longer due to their thicker shell.
