Re “Breast cancer test guidelines change” (Page 1A, Oct. 21): The American Cancer Society now says that women do not need mammograms until age 45, instead of 40. The ACS says that the medical literature shows that mammograms can result in false positives, do not reduce the likelihood of death, and can result in women being overtreated.
I strongly disagree with their conclusion. Most women would prefer a false positive over cancer. Breast cancer is more aggressive in premenopausal women than in postmenopausal women. By pushing mammograms back to 45, younger women may not even be screened.
