I don't immediately see Asian American women being exposed to additional regional air pollution, asbestos, coal soot, or radon more than others.
There could be a race-linked genetic factor, but I'm not aware of Asian women that are non-American having a higher rate. So I don't see why it would be something like... aspirated cooking oils fumes or natural gas fumes while cooking. Do Asian American households have a significantly higher likelihood of natural gas stoves? Do they have cultural histories of certain kinds of make-up or body treatments like talc?
