FRIDAY, April 14, 2017 (HealthDay News) — Breast cancer rates amongst Asian-Americans are steadily increasing in contrast to other racial/ethnic groups, a new study suggests.
Researchers from the Cancer Prevention Institute of California reviewed information from 1988 to 2013 on breast cancer among women in California from seven Asian ethnic groups. These included Chinese, Japanese, Koreans, Filipinos, Vietnamese, South Asians (Asian Indians and Pakistanis), and Southeast Asians (Cambodians, Laotians, Hmong, Thai).
For the duration of the study period, all of these groups — except Japanese females — had an general boost in breast cancer incidence. The largest increases were among Koreans, South Asians and Southeast Asians, the study authors said.
“These patterns warrant added consideration to public wellness prioritization to target disparities in access to care, as properly as additional analysis in identifying relevant breast cancer danger factors for specific breast cancer subtypes,” lead researcher Scarlett Lin Gomez mentioned in an institute news release.
Among women over age 50, there were increases in all Asian-American ethnic groups. In girls beneath 50, there were large increases among Vietnamese and other Southeast Asian groups.
Breast cancer rates amongst Asian-American women as a complete have been lower than among white ladies. But the prices among Japanese and Filipino women younger than 50 had been similar to prices for white females of the very same age.
The researchers also found that HER2 breast cancer was much more widespread among Korean, Filipino, Vietnamese and Chinese women than amongst white females. HER2 (human epidermal development factor receptor two) is a gene that plays a role in the improvement of breast cancer. The study authors noted this kind of cancer tends to develop far more swiftly and spread a lot more aggressively.
Gomez recommended that future investigation into breast cancer danger aspects in Asian women may well look at early life exposures and achievable genetic susceptibility.
The study was published in the journal Breast Cancer Study and Therapy.
