Missing Your First Mammogram May Raise Risk of Breast Cancer Death, Study Finds

Women who skip their first <span>breast cancer screening</span> may face a 40% greater risk of dying from the disease over the long term, according to a new study. The research, published in September in The BMJ, followed more than 400,000 women in Sweden over a span of up to 25 years.

<h2>When Should Women Begin Breast Cancer Screening?</h2>

The study raises important questions: at what age should women start screening, why does missing the first appointment increase long-term risk, and what other tests or self-checks might help? Dr. Leana Wen, an emergency physician and adjunct associate professor at George Washington University, weighed in on these points.

As per CNN, Wen explained that in the United States, breast cancer is the second most common cancer among women and the second leading cause of cancer death. In 2022, over 279,000 new cases were reported in women, and more than 42,000 women died from the disease in 2023.

Globally, a report from February, as per CNN, indicated that 1 in 20 women will develop breast cancer in their lifetime. Researchers estimate that by 2050, annual diagnoses could reach 3.2 million, with 1.1 million deaths worldwide.

When breast cancer is found and treated in its earliest stage, the five-year survival rate exceeds 99%, according to the American Cancer Society. Once cancer spreads to other organs, the survival rate drops to around 32%.

<h2>When Should Women Start Screening For Breast Cancer?</h2>

Last year, the U.S. Preventive Services Task Force recommended that most women begin mammograms at age 40 and continue every two years until age 74. Women over 75 should decide in consultation with their primary care provider.

For women at higher risk, screening may need to start earlier or occur more frequently. High-risk factors include prior chest radiation, certain genetic mutations, and having a first-degree relative, such as a mother or sister, with breast cancer.

The Swedish study tracked 432,775 women over up to 25 years. Nearly one-third of women invited for their first <span>mammogram</span> did not participate. Those who skipped the first screening were also less likely to attend future screenings and more likely to be diagnosed at advanced stages.

The study found that women who missed the initial mammogram were 1.5 times more likely to be diagnosed with stage 3 cancer and 3.6 times more likely for stage 4, compared to those who attended. After 25 years, death rates from breast cancer were significantly higher among the initial nonparticipants.

Researchers noted that while the findings reflect Sweden’s healthcare system, the principle that missing initial screenings increases long-term risk likely applies worldwide. An editorial in the same journal emphasized that attending the first mammogram is a long-term health investment, not just a routine check.

<h2>Why Does Delaying First Breast Cancer Screening Increase Long-Term Risk?</h2>

Wen highlighted that women who skip the first screening often continue to miss subsequent exams. Factors such as lack of awareness, access challenges, fear, and cultural influences may contribute. Late-stage diagnosis leads to lower survival rates and higher mortality.

Mammograms remain the standard screening tool for women at average risk. Higher-risk women may benefit from additional tests, such as genetic testing, breast MRI, or ultrasound. Women with dense breast tissue should discuss supplemental tests with their healthcare provider, as mammograms are less effective for detecting cancer in dense tissue.

Self-exams are not a replacement for mammograms but can help women notice changes in their breasts. If a lump or other unusual symptoms appear—such as nipple discharge, pain, swelling, color changes, inward-turning nipple, enlarged lymph nodes, or skin changes—women should consult a healthcare provider immediately.

<h2>How Can Women Reduce Their Risk Of Breast Cancer?</h2>

Lifestyle factors play a major role. Smoking, excessive alcohol consumption, and obesity increase risk. Maintaining a healthy weight, staying physically active, eating a nutritious diet, quitting smoking, and moderating alcohol intake can all lower the risk and improve overall health.
