...unsettling enough that ABC anchorman Peter Jennings died of lung cancer just four months after announcing his diagnosis. Perhaps more distressing to the 90 million--plus smokers and former smokers out there was that Jennings swore off tobacco 20 years ago and was struck by the disease all the same. It's true that he had resumed smoking after the terrorist attacks in 2001, but he quit again. Can that first puff years ago start a fatal cascade of lung damage that can never be reversed? The answer...
...point of no return, at which it doesn't matter whether you quit. Their conclusion, published in BMJ (formerly the British Medical Journal) last year: timing is everything. The sooner you quit, the more damage you undo. A smoker who quits at age 50 reduces the risk of lung disease by half. Quitting by age 30 eliminates nearly all the smoking-related risk...
...Survival rates for all lung cancer: in the first year, six out of 10 people will be dead. By the second year, eight out of 10 people will be dead. By five years, only 15% of people will survive...
...When you talk about cancer in general, there are good screening programs, like mammograms for breast cancer or colonoscopies for colon cancer. With lung cancer, there is no generally accepted screening test today. We have 100 million former or current smokers in the United States right now and a lot of them, obviously, are considered at risk for lung cancer. But we haven't agreed on a way to screen all these people. We haven't come up with a reliable program. CT scans are too expensive. And should everyone be exposed to CT scans? That's still being figured...
...quickly growing population of people with lung cancer appears to be nonsmoking women. While men still have a greater number of overall lung cancer cases, nonsmoking women are much more likely than nonsmoking men to develop cancer. We don't know why that is, but we think it might have to do with changes in hormones. Women may be more likely to develop cancer because of hormonal changes. In terms of environmental exposure, if radon is in fact a culprit in the home and more women are at home than men, that could be part of the answer...
