US cancer group advises later start to mammograms

The American Cancer Society now says women should start mammograms later in life and get fewer of them, a stance that puts the trusted group closer to an influential government task force’s advice.
In new guidelines released on Tuesday, the cancer society recommends that most women should begin annual screening for breast cancer at age 45 instead of 40, and switch to every other year at 55. The task force advises screening every other year starting at age 50.
It is not a one-size-fits-all recommendation; both groups say women’s preferences for when to be scanned should be considered.

The advice is for women at average risk for breast cancer. Doctors generally recommend more intensive screening for higher-risk women, including those with specific genetic mutations.
“The most important message of all is that a mammogram is the most effective thing that a woman can do to reduce her chance of dying from breast cancer,” said Richard Wender, the cancer society’s cancer control chief.

“It’s not that mammograms are ineffective in younger women,” he said, but at age 40, breast cancer is uncommon and false alarms are more likely.
“Therefore, you’d have to do a lot more mammograms to prevent one death,” compared with older women, Wender said.
Concern about false alarms — which lead to worry and more testing — contributed to the cancer society’s new guidance.
The guidelines were developed by experts who reviewed dozens of studies including research published since 1997 — the year the cancer group recommended yearly mammograms starting at age 40, and since 2003, when it stopped recommending monthly breast self-exams.
The update recommends that women continue getting screened as long as they are in good health and have a life expectancy of at least 10 years. The old guidelines did not include an age limit.
The cancer group also dropped a recommendation for routine physical breast exams by doctors, saying there is no evidence that these save lives.
The new guidelines say switching to every other year at age 55 makes sense because tumors in women after menopause tend to grow more slowly.
Older women’s breasts are also usually less dense so cancer is more visible on mammograms, said Kevin Oeffinger, chairman of the society’s breast cancer guideline panel and director of the cancer survivorship center at Memorial Sloan Kettering Cancer Center in New York.
The guidelines were published in the Journal of the American Medical Association.
