Breast Cancer Awareness Month Highlights Early Detection and New Research

As October marks Breast Cancer Awareness Month, the Cancer Society of Israel is releasing updated statistics and research findings. The organization estimates that by the end of 2026, approximately 5,870 women in Israel will be diagnosed with breast cancer, and about 1,100 are expected to die from the disease. Breast cancer is the most common cancer among Israeli women, accounting for one-third of new cancer cases annually, primarily affecting women over 50.

Early detection is emphasized as crucial for improving recovery rates. Moshe Bar-Chaim, CEO of the Cancer Society, stated that early diagnosis can increase cure rates to 90% or more. The national early detection program recommends mammograms every two years for women aged 50 and older. Women aged 45 and above can consult their doctor about starting screenings earlier.

Recent studies are exploring potential links between lifestyle factors and breast cancer risk. One study in Finland found that while overall night shift work showed no clear connection, women aged 50 and above who worked more than three consecutive night shifts had a 64% higher risk of breast cancer. Evening shifts were associated with a 28% increased risk. However, researchers caution that these are observational studies and further research is needed to establish causality.

Another study examined the use of GLP-1 medications, often prescribed for obesity and diabetes. In a U.S. study of overweight or obese women, GLP-1 use was linked to a 30% lower chance of breast cancer diagnosis. The researchers noted this could be related to weight loss or improved metabolic factors, not necessarily the medication itself. The Cancer Society advises against using these drugs solely for cancer prevention.

Furthermore, a large study on physical activity indicated that maintaining high activity levels throughout life reduced breast cancer risk by 8%. Women engaging in six or more hours of high-intensity exercise weekly had a 28% lower risk. Importantly, starting exercise even after age 50 was associated with a reduced risk, suggesting it's never too late to begin.

The Cancer Society also reminds eligible women, particularly those of Ashkenazi Jewish or Ethiopian descent, about free BRCA gene mutation testing available through the national health basket. Carriers of BRCA1 or BRCA2 mutations have a significantly increased risk of breast and ovarian cancers, but regular screening and preventive measures can lower this risk and enable early detection. Additionally, the organization reiterates the recommendation for biennial mammograms for women aged 50-74, with personalized recommendations for those at higher risk.
