A new study has shown that there is a lower risk of breast cancer with greater exposure to the sun. That is, the star what of light to Earth, rich in vitamin D, makes the body less likely to get breast cancer.
This is reflected in the research carried out by scientists from the University of Buffalo (United States) and the University of Puerto Rico.
The article has been published in the journal ‘Cancer Epidemiology, Biomarkers & Prevention’. During the research, a stopwatch has been used for its development to compare skin pigmentation in women exposed to the sun and in those who were not exposed to the sun. Carrying out a total of 307 cases and 328 controls.
«This study has been unique because it was of Puerto Rican women. This allowed us to see this association in a population with a wide range of skin colors and high exposure to sol throughout the year”.
This has been commented by the study’s lead author, Jo Freudenheim. She is a professor in the Department of Epidemiology and Environmental Health at the College of Public Health and Health Professions at the University at Buffalo.
Sun exposure has effects on inflammation, obesity, and circadian rhythms
The evidence exists, although the author acknowledges, that it is inconsistent. However, it has explained that exposure to sol it has effects on inflammation, obesity, and circadian rhythms.
Previous studies on this issue have been conducted in locations that experience seasonal variations in UV radiation, including periods of low or no exposure. In the case of Puerto Rico, there is no significant seasonal fluctuation.
«The risk of breast cancer was lower for women with higher cumulative sun exposure. Similarly, the risk was lower regardless of estrogen receptor status. It was even lower among the participants with a darker skin color, ”said the researcher, Cruz Nazario.
