Is breast cancer biologically different in East Asian women?
There appears to be more going on than adopting a Western lifestyle, researchers say
Patterns of breast cancer incidence appear to be different in women of European origin and East Asian women, a study shows.
Taiwanese researchers estimated age-specific breast cancer incidence rates using registry data extracted from close to one million East Asian women and more than 645,000 Americans.
“The age-specific incidences of breast cancer among East Asian women aged 59 years [or younger] increased disproportionally over recent decades relative to rates in US contemporaries,” the authors report in the Journal of the National Cancer Institute.
Between 2010 and 2014, the estimated age-specific probability of estrogen receptor (ER) positivity increased with age in American patients, the researchers note.
