Roswell Park-led study finds vitamin D influences racial differences in breast cancer risk
- Posted: April 6, 2012
American women of African ancestry are more likely than European Americans to have estrogen-receptor-negative (ER-negative) breast cancer. There continues to be discussion about the role of low levels of vitamin D in the development of breast cancer for these women. New research by a team from Roswell Park Cancer Institute (RPCI) and four other institutions has shown that specific genetic variations in the vitamin D receptor (VDR) and in CYP24A1 (responsible for deactivating vitamin D) are associated with an increase in breast cancer risk — particularly for ER-negative breast cancer — for African-American women.
Among the research institutions NCI funds across the United States, it currently designates 66 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
