DAMAGE PATROL: ENZYME MAY REVEAL CANCER SUSCEPTIBILITY Nathan Seppa (Science News, September 2003) Breaks in a person's DNA underlie the cancer-causing effects of cigarette smoke. Such DNA damage can lead to mutations that bring about the aberrant cell growth of cancer. But since not all smokers get lung cancer, scientists have assumed that some people mend their damaged DNA strands better than others do. With this in mind, researchers have been searching for enzymes that orchestrate DNA repair and mitigate cancer risk. Now, scientists report that people with lung cancer are shortchanged when it comes to at least one type of DNA
