...order, she wanted the rest of her to be checked out. Her doctor acquiesced and ordered a chest x-ray, screening blood work (both of which were fine) and a colonoscopy. During the colonoscopy, the gastroenterologist located a golf ball-sized tumor which required surgery. Subsequent pathology identified the cancer as malignant. Now in the midst of chemotherapy, Margaret and her oncologist are confident that this will take care of the cancer and that she is extremely lucky to have been diagnosed when she did. Margaret says she gets teary every time she thinks about...
...study associating drinking fluoridated water with osteosarcoma, a rare malignant bone tumor, was published last Wednesday on “Cancer Causes and Control”, an online peer-review journal of Harvard University. Elise B. Bassin, a clinical instructor in Oral Health Policy and Epidemiology, who led the study, wrote in an e-mail that she found a significant relationship between fluoride and cancer—contradicting the findings of her dissertation adviser Chester Douglass, the chair of the Oral Health Policy and Epidemiology Department at the Harvard School of Dental Medicine. “We found an association...
...bladder has been successfully grown and accepted by a patient. In the past, similar transplants were done using tissue samples from other organs or through organ donors. Building a bladder from other tissue has often resulted in numerous complications, including rejection of the organ, bone loss, and even cancer. Scientists believe that the widespread use of lab-grown organs may ease the massive shortage of requests for organ transplants, which currently stands at nearly 92,000, according to the United Network for Organ Sharing. Organ requests outpace donations by nearly a two to one margin. In the study, seven children...
...others pray for them, according to a 2004 survey conducted by the National Center for Health Statistics. Terri Cisse, a graduate student at the Harvard Divinity School, questioned the validity of the study. “I’ve seen firsthand from working at the Dana-Farber Cancer Institute how people are consoled by prayer. Prayer is so transcendent and metaphysical that it can’t be measured scientifically,” she said. “There are different rubrics for evaluating science and religion.” Critics of the study, including Dr. Mitchell Krucoff...
...trials that are the gold standard of science. Epidemiological studies are very good at identifying possible trends and associations, but they are not designed to prove cause and effect. That's not necessarily a problem. No one has ever done a randomized trial of smoking, yet it clearly causes cancer. On the other hand, it was on the basis of good epidemiological evidence that doctors believed for years that long-term use of estrogen and progestin would significantly protect women from heart disease. When the theory was put to the test with a randomized, controlled trial, however, it turned...
