But some experts believe the panel overstated the harms of more frequent screenings. The appropriate schedule for screenings can vary from doctor to doctor, and patient to patient, and has become quite confusing.
“Many women may not even be aware of the guidelines, or that there may be any downside to mammography, and that they have the option to begin screening at age 45 or 50,” Dr. Jennifer L. Marti, an assistant professor of surgery at Weill Cornell Medicine who led the new study, said in an interview. “In almost every other country, women start at 50.”
While many women might assume that “the pros of breast cancer screening outweigh the harms,” Dr. Marti said, that is not always the case for women who aren’t at elevated risk.
Dr. Marti and her co-authors, Mark Lee and Neal Patel, two Weill Cornell researchers, decided to examine the recommendations posted on the websites of some 606 breast cancer centers in the United States. They found that 376 centers — over half — made recommendations that differed from those of the U.S. task force, saying women at average risk for breast cancer should start imaging at age 40.
And 347 centers said women should not only start at 40, but continue annually.
More rigorous screening may be appropriate for some high risk groups, like Ashkenazi Jewish women, who are more likely to carry mutations that put them at risk for breast and ovarian cancer, and Black women, who were likely underrepresented in mammography screening trials, Dr. Marti said.
Women who want help assessing their individual risk to make screening decisions can use an online tool developed by Dr. Margaret Polaneczky, a gynecologist from Weill Cornell Medicine, and Elena Elkin, a research scientist at Memorial Sloan Kettering Cancer Center, Dr. Marti suggested.
As for myself, I’ve been on a two-year plan for a while. I do regular breast self-examinations, and have clinical breast exams too. So even though I felt a smidgen of irrational guilt after receiving the text messages, I politely asked a receptionist to please stop calling. I promised I’d be in touch.
