Cancer screening has come under stricter review recently. After a government expert panel recommended in October that people stop getting the prostate-specific antigen blood test for prostate cancer since it does not save lives, wrought iron manufacturers. New research on colonoscopy's limitations - it is not a randomized clinical trial, but some experts say it is well done and helps answer questions about the procedure's effectiveness. "Not all adenomas turn into cancers and not all cancers lead to death," said Ann Sakai, the study's main author and a statistician at Sloan Kettering. But, she said, "in many cases we are getting those with the potential to go on and cause cancer deaths." "This study puts this argument to rest," said Dr. David Rothenberger, professor and vice chairman of surgery at the University of Minnesota Masonic Cancer Center. He was not involved in the study. Even if intestinal cancer has been established, it can still be cured if detected and treated early. Intestinal tumors are one of the leading causes of cancer death in the U.S., and one of the few cancers that can be prevented and screened. This year, more than 143,000 new cases and 51,000 deaths are expected. The incidence and mortality rate have fallen for about 20 years, possibly due to increased use of screening tests and better treatment. But only about six out of ten adults have been screened for intestinal cancer thus far, according to federal budgets. Researchers reported Wednesday in the New England Journal of Medicine that after tracking patients for up to 20 years, the mortality rate from intestinal cancer was cut by 53% among those whose doctors called precancerous growths, adenomatous polyps, during these trials. The examination inspects the small intestine with a camera-tipped tube. Earlier studies have shown that removing precancerous polyps can significantly reduce the incidence of intestinal cancer. But a major question remains: Does clearing polyps really save lives? Theoretically, it is possible that if doctors find growths, patients will not die or miss people who might die. Robert Smith, senior director of cancer control at the American Cancer Society, said, "This is a big question." A research team led by Sidney Winawer, gastrointestinal memorial Sloan-Kettering Cancer Center in New York City, removed 2602 cases of adenomatous polyps during colonoscopies between 1980 and 1990. Doctors compared their colorectal cancer mortality rates with the general population, where 25.4 deaths from the disease were expected in a group of the same size. However, in the polyp group, a total of 12 people died of colorectal cancer, which would reduce the mortality rate by 53%. Although doctors differ on the best methods, they all agree that it is important to think through the various types of tests, usually starting at age 50. Screening is worthwhile because colorectal cancer is one of the few cancers (cervical cancer and skin cancer precancerous lesions, etc.) and a disease that can be prevented if those growths are detected and cut off. Studies show that not every polyp turns into cancer, but almost every large tumor starts as an adenomatous polyp. A new study provides the best evidence from independent research, colonoscopy - perhaps the most beloved screening test - prevents death. Although many believe that colonoscopy must save lives because it is often recommended, there has always been a lack of strong evidence until now.

Tests outside of colonoscopy look for blood in the stool or use different techniques to inspect the small intestine. All tests are unpleasant, www.mystseo.com, and people often refuse them. (Jieyang station promotion www.wji.cc) "For any cancer screening test, reducing cancer-related mortality is the holy grail," said Dr. Gina Vacarro from the Knight Cancer Institute at Oregon Health & Science University, who was not involved in the study. "This study shows that mortality is reduced if polyps are removed, and 53% is a very strong reduction."
