Timing of Mammograms May Be Crucial in Tumor Detection

Results of a Canadian study suggest that performing a mammogram in the first half of a woman’s menstrual cycle may make the procedure both more comfortable and more accurate. The study revealed that there was an 11 percent greater risk that a tumor would not be detected when a mammogram was performed in the second half of the menstrual cycle. American Cancer Society epidemiologist and mammography expert Robert Smith said that the findings are not significant enough to warrant an official recommendation on the timing of mammograms. However, the study does suggest that the menstrual cycle can influence breast cancer diagnosis and treatment.
