Among the many difficult decisions women face after receiving a diagnosis of breast cancer is whether to undergo mastectomy, not only of the breast with cancer but, as a preventive measure, of the unaffected breast as well. Cancer detected in one breast has a tendency to spread to the other, healthy breast, and an increasing number of women are choosing to excise the unaffected breast, just to be safe.

For the majority of women diagnosed with the disease, the drastic and deforming surgery is more than they need, the study concludes. (See the top 10 medical breakthroughs...
...Bedrosian's study, however, which involved 107,000 women undergoing mastectomy for breast cancer, most women did not obtain a survival benefit from preventive surgery in the unaffected breast. Only a specific group of patients - women under age 50 who had early-stage cancer (I or II) and tumors that were negative for the estrogen receptor - saw an increase in their chances of surviving to five years. That increase was small, just 4.8%, compared with women who did not have preventive mastectomy. Further, less than 10% of the breast-cancer population fits these criteria...

A Scottish judge freed al-Megrahi on compassionate grounds, saying he was almost certain to die of cancer within three months. Saturday marked the six-month anniversary of al-Megrahi's homecoming, which unleashed huge rejoicing among Libyans and condemnation from Washington. A U.S. trade mission was slated for last November but was scrapped when White House officials intervened, saying the feelings over al-Megrahi were still too raw, according...
