Breast Cancer Screenings: Why Doctors Say Earlier Detection Matters

More than 322-thousand new cases of invasive breast cancer are expected to be diagnosed in women across the United States in 2026 alone, according to health experts. While breast cancer is more commonly diagnosed in middle-aged and older women, doctors say they are also seeing a slight increase in cases among younger women. Recent data shows new breast cancer cases in women under 50 have increased by about 1.4 percent — raising concerns among physicians about awareness and screening practices.

One issue experts point to is confusion surrounding mammogram recommendations. “There is a different recommendation out there depending upon what literature you’re citing,” said Dr. Alyssa Cubbison. Doctors rely on national guidelines to determine when women should begin routine screenings, but those recommendations can vary between organizations. The U.S. Preventive Services Task Force currently recommends women begin mammograms at age 40 and continue screening every other year.

Meanwhile, the American Cancer Society says women at average risk can choose to start annual mammograms at age 40, should begin yearly screenings at age 45, and can transition to every other year at age 55 or continue annual screenings if they choose. According to American College of Radiology and the Society of Breast Imaging, annual screenings beginning at age 40 remain the preferred recommendation. “Based on our guidelines for the American College of Radiology and the Society of Breast Imaging, we recommend starting at age 40 every year,” Cubbison said.

Doctors worry conflicting guidance may cause some women to delay mammograms, potentially leading to cancers being discovered at a later stage when treatment can become more difficult. Experts also stress that family history is not the only risk factor. “Most women that are diagnosed with breast cancer have no attributable family history of breast cancer,” Cubbison explained. Because of that, physicians encourage women to discuss their personal risk factors with a doctor early in adulthood. Cubbison recommends women complete a breast cancer risk assessment survey around age 25. “Knowing this can help know at what age it’s most appropriate to start screening,” she said. Health experts say understanding personal risk and staying informed about screening guidelines can play a critical role in early detection and improving outcomes.
