Male breast cancer screening (mammogram) can effectively identify men who are at high risk of developing breast cancer, reveals a new study.
Screening mammography can detect men who are a higher risk of developing breast cancer, reports a new study. The findings of the study are published in the journal Radiology.// Selective mammography screening can provide potentially lifesaving early detection of breast cancer in men who are at high risk for the disease, according to a landmark study.

Breast cancer in men is a rare but often deadly disease. The American Cancer Society projects that 2,670 new cases of invasive breast cancer will be diagnosed in men in 2019, and about 500 men will die from it.Read More..
There are no formal screening guidelines for men in high-risk groups such as those who have a personal history of the disease, breast-cancer-associated genetic mutations or family members who had breast cancer. As a result, men diagnosed with breast cancer tend to have worse outcomes than women.
"Mammographic screening has helped improve the prognosis for women with breast cancer," said study lead author Yiming Gao, M.D., from the Department of Radiology at New York University Langone Medical Center in New York City. "But men don't have any formalized screening guidelines, so they are more likely to be diagnosed at a more advanced stage and often don't do as well as women."
There is anecdotal evidence that selective screening with mammography in men with identifiable risk factors is beneficial, but little is known as to how and to what extent breast imaging is used in this population.
In the first study of its kind, Dr. Gao and colleagues evaluated breast imaging utilization patterns and screening outcomes in 1,869 men, median age 55, who underwent mammography over a 12-year period.

"These results show that it is possible to detect male breast cancer early, and it appears that mammography is effective in targeted screening of high-risk men," Dr. Gao said. "We've shown that male breast cancer doesn't have to be diagnosed only when symptomatic."

Personal history of breast cancer was the most significant risk factor associated with breast cancer in men. Ashkenazi Jewish ancestry, genetic mutations, and first-degree family history of breast cancer were also significant factors.
Currently, the National Comprehensive Cancer Network (NCCN) does not support screening because of a lack of evidence, even in men with elevated risk. Earlier NCCN guidelines suggested consideration of baseline mammograms on an individual basis, an approach the new study results may support.
Moving forward, the researchers hope to see larger multi-institutional studies that have the statistical power to delineate more nuanced information based on different breast cancer risk factors in men.
"Rethinking our strategy toward male breast cancer diagnosis is necessary," Dr. Gao said. "We hope these results will provide a foundation for further investigations, and potentially help pave the way to standardizing screening for certain high-risk groups of men."
