Rethinking: Ideal Screening Age for Breast Cancer in Developing Countries

Area of Science:

• Oncology
• Public Health
• Epidemiology

Background:

• Breast cancer incidence varies globally, with distinct patterns observed in developing countries.
• Traditional Western screening guidelines may not be optimal for all populations.

Purpose of the Study:

• To determine the optimal age for breast cancer screening in developing nations.
• To identify appropriate early detection methods tailored to community readiness and patient age.

Main Methods:

• A 30-year retrospective review of breast cancer patient records (1984-2014) at King Fahd Hospital of the University, Saudi Arabia.
• Analysis of demographic data, age at diagnosis, and presentation time.
• Review of radiological and histopathological records for diagnostic confirmation.

Main Results:

• Out of 235,339 females, 1,832 (0.8%) were diagnosed with breast cancer.
• 35% of patients were diagnosed before age 40, challenging the notion of higher predilection in older women.
• Mammography was highly effective (100%) for women over 40, while ultrasonography was primarily used for those under 40 (43%).

Conclusions:

• A significant proportion of breast cancer cases in developing countries occur in women under 40.
• Western-based screening strategies require cultural adaptation and community-specific tailoring.
• Lowering the screening age by a decade could enhance early detection and improve outcomes in developing countries.
