Breast cancer incidence has been steadily increasing over the past few decades in Asia, according to data from the Institute for Health Metrics and Evaluation (IHME), due to various environmental, demographic, and reproductive factors. It ranks as the most common malignancy in females in most countries. The lifetime risk of breast cancer is as high as 1 in 8 in the US.
In Thailand, breast cancer incidence has increased over the past 20 years and is now the number one female cancer with an age-standardised rate of 28.5 cases per 100,000 person-years.
