Plus the rate of false positives is high, as is false negatives. agreed (I'm not sure I agree with "high"). But, so? If we expect people to take care of themselves then we can also ask them to be aware of false negatives. False positives can only lead to unnecessary, maiming, surgery if doctors are trigger-happy. > A.A. Environmental causes of breast cancer are unclear. If heredity were the only factor, it would be pretty hopeless. Some cases of breast cancer are, quite simply, pretty hopeless. Some (apparently) require (in the US, anyway) the prophylactic removal of the ovaries and womb. > A.A. Presumably therefore you are investigating the reasons behind falling and getting >injured? Behind my falling? No. There's no continuing cause of falling as there are no continuing falls. (But I have had a brain scan for other reasons: all clear. My muscles are now a little weak but were then strong. My balance, well, then I could do the yoga stands.) Irene, you might just as well insist that I look into the reasons why my mother was in the car crash that caused her neck arthritis. > >I've never heard that osteoarthritis is caused by falls. > >Arthritis, not osteoarthritis, is caused by injury to joints (I think we agree you were wrong when you said "arthritis, not osteoarthritis") osteoarthritis can be caused by injury/injuries and falls can cause injuries. >Doctors can hand out pills to supposedly reduce inflammation, >which ultimately backfires and makes the situaion worse, or they can do surgery. to me, you mean? My knee surgeon's very good. He prefers not to operate for the condition. He sent me to a physio. (My hand surgeon, who found osteophytes in my neck, takes a similar view.) And I walk -- I haven't got a car, so I walked anyway. IOW, doctors can do more than operate or suggest medication. > I suppose Tony Snow is one of the statistics regarding the futility of testing Many people with cancer are testimony to its non-futility, as are many with diabetes. You might want to distinguish between mass screening of the asymptomatic, and diagnostic testing of the sick.
