Because substances in tobacco are such strong carcinogens, avoiding smoking can significantly decrease one's chance of developing cancer. Smoking causes many kinds of cancer, not just lung cancer. Cancer of the mouth, larynx, esophagus, kidney, bladder, pancreas, and uterine cervix all have in common cigarette smoking as a major cause.
Research also continues to be done on ways to help people stop smoking.
Smoking is addictive and can be very difficult to quit once you have started. It has been shown over and over that finding cancers early saves lives. If a tumor is located early when it is smaller and has not spread, the prognosis for the person with the cancer is better. Researchers are looking for new ways to increase the precision, accuracy and scope of imaging techniques to find cancers earlier. These advances are very exciting and may soon impact treatment decisions.
