Scientists who examine and investigate ethnic biology of cancer stated on Monday that a gene based characteristic shields many women of Latin American Descent from breast cancer.
If the trait is fully confirmed, it may pave the way for better genetic testing for females at the risk by helping to decide that which individual needs to be the most careful and must take appropriate measures to prevent the same. Breast cancer being the most popular cause of cancer in females, this holds importance to the researchers.
Normally, lesser Hispanic females have breast cancer and even lesser of them die from the cancer when in comparison women having African-American or European ancestry, according to the medical stats. An international team led by scientists from the University of California in San Francisco on Monday stated that they know the reason behind it.
One single difference in one out of the 3 billion letters biochemical code of DNA that comprises our traits in makes Latinas who have about 40 percent lesser risk of developing breast cancer, according to the medical geneticist Laura Fejerman and her fellow colleagues who stated it in Nature Communications.
If women got the variation from both maternal and paternal side of her family, they are twice as much, which is 80 percent less likely to develop breast cancer.
“It is strongly protective,” said cancer specialist Elad Ziv at the UCSF Helen Diller Family Comprehensive Cancer Center, who helped conduct the study funded by the National Cancer Institute. “We really need to do more experiments to nail it down and understand what it is doing.”
