Not sure about the validity of the source but it does suggest that second hand smoke could be related. "What’s behind this rise in lung cancer in women who have never smoked compared with men, and particularly in Asian American women? One possibility: While Chinese American women may never smoke themselves, they frequently live with partners or family members who do. (About 28% of Chinese American men smoke heavily, Dr. Li said.) “We think secondhand smoke might be one of the key risk factors, because they’re living with people who smoke,” Dr. Li said."

I could see a possible scenario where a first generation (i.e. immigrant, English as a second language) Asian father/husband smoking at home in the 1990-2010 timeframe and not getting the second hand smoking messages/ads (that were primarily in English as quickly) as the rest of Americans and it's is just now that the statistics are showing up.
