...skin cancer discovered on President Clinton is the most common and easily curable form of the disease. Most cases of this cancer, known as basal cell carcinoma, are caused by exposure to UV radiation, primarily from the sun, and can be cleanly removed with surgery. The lesions, which were found during the President's annual physical on Friday, enlarge over a period of months and even years, and are distinguished by their shiny, firm appearance and ivory-colored borders. Some growths bleed and heal repeatedly, making it easy to mistake them for sores instead of tumors...
...most common treatment for basal cell carcinoma, and the one used by Clinton's doctors, involves scraping away the cancerous cells layer by layer and zapping surrounding tissue with an electric needle. This can be done in an office with local anesthesia. Recurrence of small tumors treated this way is about 5 percent. For larger tumors, more invasive surgery, lasers, directly applied chemotherapy agents, or liquid nitrogen are used to kill the cancer cells...
KIDNEY CONCERN Here's a powerful reason to keep your weight--and blood pressure--under control. Folks who are obese have twice the risk of renal-cell carcinoma, the most common form of kidney cancer. High blood pressure also increases the risk of developing the cancer, with the odds doubling when readings exceed 160/110. Exactly why is unclear, but it is known that hypertension can damage the kidneys, which may make them vulnerable to carcinogens...
...hedgehog--they have been able to awaken hair follicles from a resting state and force them into an active one. Alas, that's just in mice. Whether the therapy works on human pates remains to be seen. One potential problem: the Sonic hedgehog gene is linked to basal-cell carcinoma, a common, treatable skin cancer...
...consider hormone-replacement therapy but fear that the estrogen in HRT will increase their risk of breast cancer. The jury is still out, but here's some reassurance. A study of 37,000 women found little evidence that estrogen is linked to common types of cancers such as ductal carcinoma in situ (a cancer confined to a duct). It may, however, increase some uncommon forms--but they are slow growing and may be easily treatable...
