Detailed explanation-1: -Lung cancer is a disease caused by uncontrolled cell division in your lungs. Your cells divide and make more copies of themselves as a part of their normal function. But sometimes, they get changes (mutations) that cause them to keep making more of themselves when they shouldn’t.

Detailed explanation-2: -Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.

Detailed explanation-3: -Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body (malignancy), and even result in death.

Detailed explanation-4: -Lung cancer develops when normal lung cells change, or mutate, in a way that alters their natural growth and death cycle, resulting in unregulated cell division that produces too many cells. The rapidly dividing cells do not carry out the functions of normal lung cells or develop into healthy lung tissue.

Detailed explanation-5: -Lung cancer is a disease in which cells mutate (change) and begin to grow in an abnormal and uncontrolled way in the lungs. These cells are unable to function like healthy lung cells and as they grow they can form tumors and interfere with lung function.
