"Just seven years ago, the same group, the United States Preventive Services Task Force, with different members, recommended that women have mammograms every one to two years starting at age 40. It found too little evidence to take a stand on breast self-examinations.
The group’s new guidelines, which are different from those of some professional and advocacy organizations, are published online in The Annals of Internal Medicine They are likely to touch off yet another round of controversy over the benefits of screening for breast cancer."
