Routine mammograms for screening breast cancer after the age of 75 years should be based on a woman’s personal choice, her health and other illnesses that she might be facing, and not on age, a new study suggested.

A team of researchers led by Dr. Cindy Lee, a professor at UC-San Francisco, analyzed nearly 7 million mammograms over a period of seven years, and concluded that the benefit of the screenings continues with increasing age up until 90.

Sharing findings of the new study, Dr. Lee said, “The continuing increase of cancer detection rate and positive predictive values in women between the ages of 75 and 90 does not provide evidence for age-based mammography cessation.”

Until now, women 75 and over weren’t encouraged to get routine mammograms to screen for the potentially deadly disease of breast cancer. Previous guidelines of the 2016 U.S. Preventive Services Task Force would suggest women between age 50 and 74 to go for a mammogram once every two years.

Mammograms provide a better look at breast tissue by using X-Ray imaging. However, the technology has been controversial, particularly over the question of whether or not it saves people’s lives.

The findings were presented at the Radiological Society of North America’s most recent annual conference in Chicago. It may be noted here that a study presented at a medical meeting is viewed as preliminary until it is published in a peer-reviewed journal.
