A large Swedish study shows that women who skip their first breast cancer screening could face a 40% higher risk of dying from the disease in the long run. This research, published in The BMJ, followed over 400,000 women for up to 25 years.
Breast cancer is the second most common cancer and cause of cancer death among women in the U.S. Early detection is key. When found early, breast cancer’s five-year survival rate exceeds 99%. But the rate drops sharply if the cancer spreads.
The U.S. Preventive Services Task Force now recommends women start mammogram screenings at age 40 and continue every two years until age 74. Women at higher risk, including those with genetic mutations or family history, should discuss earlier and more frequent screenings with their doctors.
The study found that nearly one-third of women did not attend their first invited screening. These women were also less likely to attend future screenings and more often had advanced stages of cancer when diagnosed. Their risk of being diagnosed with stage 3 or 4 breast cancer was significantly higher, leading to more deaths over 25 years.
Experts say missing the first screening often leads to missing later ones. Barriers include lack of awareness, fear, and cultural factors. Besides mammograms, high-risk women may benefit from additional tests like breast MRI or ultrasound. Breast self-exams are not a replacement for mammograms but can help women notice changes that require medical attention.
To lower breast cancer risk, experts advise quitting smoking, reducing alcohol, maintaining a healthy weight, being physically active, and eating a nutritious diet.
