The organisation also said it no longer recommended clinical breast exams, in which doctors or nurses feel for lumps, for women of any age who have had no symptoms of abnormality in the breasts.Previously , the society recommended mammograms and clinical breast exams every year, starting at 40. The changes reflect increasing evidence that mammography is imperfect, that it is less useful in younger women, and that it has serious drawbacks, like false-positive results that lead to additional testing, including biopsies.
But the organisation's shift seems unlikely to settle the issue. Some other influential groups recommend earlier and more frequent screening than the cancer society now does, and some recommend less, lea ving women and their doctors to sort through the conflicting messages and to figure out what makes the most sense for their circumstances.
However, the American Cancer Society carefully tempered its language to leave plenty of room for women's preferences. Though it no longer recommends mammograms for women ages 40 to 44, it said that those women should still "have the opportunity" to have the test if they choose to, and that women 55 and older should be able to keep having mammograms once a year.
