Lung Cancer a Woman's Disease (Science/Technology, 6 articles)
|
The test looks for raised levels of a chemical called prostate specific antigen (PSA), which can be sign of cancer. However, the test is far from infallible, and now University of Texas researchers have found obesity is associated with lower PSA levels. A new study suggests that a man's weight might affect the accuracy of a common test to detect prostate cancer, leading researchers to warn that doctors could be missing the dangerous cancer in obese men. What many don't realize is that lung cancer is the leading cancer killer of women, responsible for 27 percent of all cancer deaths, ahead of breast and colorectal cancer, according to the latest federal statistics. And women may be more susceptible to the disease than men, research suggests, a fact many women and their doctors may not realize. Eating lots of fruit and vegetables and limited amounts of red meat and sugary foods is the way to protect against cancer, say researchers. Since earlier research suggests that the same natural plant substances might also help prevent the development of prostate cancer, scientists say that more studies are needed on green tea's ability to fight this common cancer.
