New Data Reveals Breast Cancer Trends and Risk Factors in Israel

New data released by the National Cancer Society in Israel indicates that approximately 5,870 women are expected to be diagnosed with breast cancer by the end of 2026. This translates to about 113 new cases weekly and an estimated 1,100 deaths annually from the disease. Breast cancer currently accounts for one-third of all new cancer cases among women, predominantly affecting those over 50. However, the society emphasizes that early detection significantly improves outcomes, with cure rates reaching 90% or higher.

To enhance early detection, women aged 50 to 74 are advised to undergo mammograms every two years as part of the national health basket. Women identified as high-risk are encouraged to start screenings as early as age 40. Additionally, healthy women of Ashkenazi or Ethiopian descent are recommended to take a free blood test at their health fund to screen for genetic mutations in the BRCA1 and BRCA2 genes. Appropriate monitoring for carriers of these mutations can prevent an estimated 280 breast and ovarian cancer cases each year.

Alongside screenings, maintaining a healthy lifestyle, including avoiding alcohol and maintaining a healthy weight, is crucial for risk reduction. Recent international research is shedding further light on risk factors and prevention. A Finnish study found that among women aged 50 and above, working more than three consecutive night shifts was linked to a 64% increase in breast cancer risk. Conversely, an American study suggested that using GLP-1 weight-loss medications was associated with a 30% lower risk of diagnosis, likely due to weight loss and metabolic improvements.

Furthermore, a Norwegian study indicates that engaging in at least six hours of vigorous physical activity per week reduces breast cancer risk by approximately 28%. The researchers highlighted that even starting such exercise routines after age 50 contributes to this risk reduction.
