Cancer develops when normal cells from any tissue of the body become mutated, allowing for uncontrolled cell growth and the development of tumors. One cancer treatment uses chemotherapy drugs that halt cell growth and trigger cell death, thus...
Lung cancer can affect the airways or the air sacs deep within the lungs. Patients with cancerous growth in the lungs develop a number of symptoms of tumor growth, such as difficulty breathing, shortness of breath, persistent coughing and coughing...

A normal, healthy body detects and removes cancerous cells before they spread and cause disease. Mutations in genes that control normal cancer surveillance or that allow abnormal cells to evade it can increase a person's risk for developing...
Chemotherapy uses drugs to destroy cancer cells in the body. A cancer patient generally receives chemotherapy for a specific amount of time, after which the cancer is re-evaluated to determine whether it has been successfully destroyed or whether...
