According to the 2023 Cancer Registry data released by the Health Promotion Administration and the 2024 cause-of-death statistics from the Ministry of Health and Welfare, breast cancer ranks first in standardized incidence and second in mortality among women in Taiwan. To enhance early detection and reduce mortality risk, the Health Promotion Administration expanded eligibility for subsidized mammography screening in 2025, offering women aged 40 to 74 one free screening every two years.

Statistics show that 1.26 million women underwent breast cancer screening in 2025, an increase of 36.3% compared to previous years. Among them, approximately 326,000 women aged 40–44 and 70–74 were newly included, accounting for 25.9% of total screenings, indicating a significant rise in coverage following the policy expansion.

Mammography is currently the most evidence-based screening tool for breast cancer, capable of detecting microcalcifications and early-stage tumors before symptoms appear. The procedure is brief and involves low radiation exposure. Studies indicate that regular screening can reduce late-stage breast cancer incidence by 30% and mortality by 41%. When detected early and treated promptly, the five-year survival rate can exceed 99%. Registry data from 2023 show that 62.9% of cases identified through screening were at early stages (stage 0+1), compared with only 34.9% among those not screened.

The Health Promotion Administration encourages eligible women to schedule regular screenings and establish consistent preventive care habits to safeguard their health.
