Content Summary :
What You Need To Know About TM Lung Cancer. Cancer Cells Cancer begins in cells, the building blocks that make up tissues. Tissues make up the organs of the body. Normal, healthy cells grow and divide to form new cells as the body needs them. When normal cells growold or get damaged, they die. New cells take theirplace. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and oldor damaged cells do not die as they should. The build-up of extra cells often forms a mass of tissue called agrowth or tumor. Tumor cells can be benign (not cancer) or malignant (cancer). Benign tumor cells are usually not as harmfulas malignant tumor cells: • Benign lung tumors —are rarely a threat to life —usually do not need to be removed —do not invade the tissues around them —do not spread to other parts of the body • Malignant lung tumors —may be a threat to life —may grow back after being removed —can invade nearby tissues and organs —can spread to other parts of the body
