Breast Cancer Screening Guidelines for Women Under 40: What You Need to Know

Young Women Urged to Be Aware of Breast Cancer Risk

While breast cancer is often associated with older women, recent data shows that it is becoming increasingly common among younger women. According to the Centers for Disease Control and Prevention (CDC), about 11% of all breast cancers occur in women under the age of 45, with an estimated 26,393 cases expected to be diagnosed this year alone.

Dr. Liva Andrejeva-Wright, a radiologist specializing in breast imaging at Yale Medicine, emphasizes that breast cancer can and does affect women in their 20s and 30s. “I have diagnosed women in their 20s with breast cancers,” she says, highlighting the importance of early detection and screening.

In light of these statistics, the U.S. Preventive Services Task Force (USPSTF) recently updated its guidelines on mammography screening, recommending biennial screening for women aged 40 to 74. However, the American Cancer Society (ACS) suggests optional annual screening for women in their 40s and annual screenings for those in their 50s and beyond.

Breast oncologist Dr. Andrea Silber notes that while most breast cancers are detected in women over 50, younger women should still be vigilant about their breast health. “Women under 40 are generally too young to begin screening unless they have specific risk factors or symptoms,” she explains.

With breast cancer being the most common cancer among women aged 15 to 39, it is crucial for young women to be aware of their risk and to prioritize regular breast self-exams and discussions with their healthcare providers. Early detection can significantly improve outcomes and save lives, regardless of age.
