The researchers found that Chinese women are more likely to be diagnosed with early stages of cancer.
“Research has long suggested minority groups are among the least likely to be screened for breast cancer, impacting their survival rates and outcomes,” said Ophira Ginsburg, scientist at Women’s College Research Institute in Canada.
“For many reasons, including ethno-cultural factors, women in these groups are not receiving the screening they need, when they need it most. Our findings suggest, we have to find better ways to educate and screen these groups so that they can live longer and healthier lives,” Ginsburg noted.
The researchers compared breast cancer stage at diagnosis between Chinese women and the general population (women with breast cancer in Ontario, who were not identified as either Chinese or South Asian) and between South Asian women and the general population.
From an analysis of more than 41,000 patients diagnosed with breast cancer between 2005 and 2010, the researchers found that South Asian women were more likely to be diagnosed with breast cancer at stages II to IV compared to the general population.
Chinese women were more likely to be diagnosed at stage I and were less likely to be diagnosed with a higher stage of cancer than the general population.
Fewer South Asian women had a history of breast cancer screening in the past three years, prior to diagnosis, the findings showed.
“Cultural factors, cancer fears and stigma may pose barriers for these women when seeking care for breast problems,” Ginsburg said.
The study was published in the journal Current Oncology.
