Why personalized breast cancer screening is drawing more attention

ByBrian “Weence” Bateman

A large U.S. trial is putting risk-based breast cancer screening in the spotlight. The main takeaway for readers: it looks promising, but it has not replaced current screening guidance, and people should not change their schedule on their own.

Breast cancer screening is getting more personal. A large U.S. study published in JAMA and summarized by the National Institutes of Health found that screening based on a woman’s risk factors can find breast cancer about as well as the usual age-based approach.

That does not mean everyone should switch today. Current U.S. guidance still relies heavily on mammograms by age and risk, and people at higher risk may still need MRI plus mammography.

Why this study is getting attention now

The NIH says the WISDOM trial compared two approaches in about 28,000 women ages 40 to 74 over five years. One group had yearly mammograms. The other got screening recommendations based on personal risk, with follow-up that could include more frequent imaging, MRI, and counseling for risk reduction.

In plain language, the study tested whether screening could be matched more closely to a person’s chances of developing breast cancer instead of using age alone.

What the study found

According to the NIH summary, the personalized approach worked as well as yearly mammograms at finding breast cancer. The trial’s main result was that the risk-based approach was noninferior to the standard approach, meaning it did not perform worse by the study’s pre-set standard.

One important limitation for everyday readers: this was not a simple “less screening, same outcomes” story. The NIH summary says biopsy rates were not lower in the personalized group. So while the approach may reduce some unnecessary screening, it did not clearly reduce all follow-up testing.

The PubMed record for the trial identifies it as a randomized clinical trial, which is a strong study design, but it still needs to be interpreted alongside current guideline recommendations and each patient’s risk profile.

How this fits with current U.S. screening guidance

The CDC says mammograms are the best way for many women to find breast cancer early, before it causes symptoms. CDC also notes that screening is meant to find cancer before symptoms start, when treatment is often more effective.

MedlinePlus explains that MRI screening is generally reserved for people at high risk, and it may be used with a mammogram each year for those with a lifetime risk above about 20% to 25%. It also notes that MRI can find more cancers but can also create false alarms.

The American Cancer Society likewise says women at high risk should usually get both a breast MRI and a mammogram every year, typically starting at age 30. It also says MRI should be used in addition to, not instead of, mammography.

Who may benefit most from risk-based screening

Risk-based screening may be especially helpful for people whose risk is not well captured by age alone. That can include people with a strong family history, known BRCA1 or BRCA2 mutations, prior chest radiation at a young age, or certain inherited cancer syndromes.

For higher-risk people, the goal is not to do less care. It is to match the test to the risk, which may mean MRI plus mammography and more frequent follow-up.

What readers can do now

Do not change your breast cancer screening schedule on your own because of this study. If you are due for screening, keep that appointment unless your clinician tells you otherwise.

If you have questions, bring up your family history, prior biopsies, breast density, genetic testing history, and any cost or insurance concerns. A clinician can help estimate your risk and explain whether standard mammography or higher-risk screening may make more sense for you.

For now, the practical takeaway is simple: personalized screening looks promising, but current screening decisions still need to be made with a clinician and the guidance that already exists.
