Washington, DC: Indian and Pakistani women are diagnosed with breast cancer, including more aggressive forms, at a younger age, according to a study that provides an insight into understanding the risk factors influencing the disease.
The study, published in the International Journal of Cancer, examined the characteristics of breast cancer among Indian and Pakistani-American and non-Hispanic white women in the US using data from the National Cancer Institute’s Surveillance, Epidemiology and End Results Program.
Both, Indian and Pakistani women are diagnosed with more aggressive forms of the disease, at a younger age, according to the researchers.
The researchers, who are part of the Rutgers School of Public Health and Rutgers Cancer Institute of New Jersey, reviewed incidence data among Indian and Pakistani women between 1990 and 2014.
“Our results provide an insight into breast cancer in Indian and Pakistani women, suggesting several hypotheses to guide future scientific studies to better understand the risk factors influencing disease aetiology and prognosis,” said Jaya M Satagopan, lead author and director of the Center for South Asian Quantitative Health and Education at the Rutgers School of Public Health.
South Asians are the fastest-growing major ethnic group in the United States with breast cancer rates increasing within the population, but little is known about the disease in this socio-culturally unique population, according to the study.
The researchers also reviewed the disease characteristics, treatment and survival data between 2000 and 2016 for 4,900 Indian and Pakistani women and 482,250 non-Hispanic white women with breast cancer.
They found that the occurrence of breast cancer in Indian and Pakistani women was lower than in non-Hispanic white women, however, the number of Indian and Pakistani women diagnosed with breast cancer increased over the years.
While the researchers found that Indian and Pakistani women were less likely to die of breast cancer than their non-Hispanic white counterparts, their health was tracked for a shorter time.
Prior cancer research has shown that fewer Indian and Pakistani women participate in scientific studies and that several socio-cultural factors may delay their seeking health care.
Research also has shown poor mammogram screening rates in Indian and Pakistani women, which is linked to a lack of family support, lack of transportation, modesty, fear, beliefs that cancer is divine punishment for past deeds, having lived in the United States for less than 10 years, low English proficiency and a lack of faith in the health system.
