Sunlight reduces the risk of breast cancer, according to a new study by scientists at the University of Buffalo and the University of Puerto Rico in the United States.
The researchers used a chromometer for a comparative study of factors controlling skin pigmentation in sunlight and non-sun conditions. The general concept of exposure to sunlight is based on differences in skin pigmentation. The study, conducted in Puerto Rico, was published in the Journal of Cancer Epidemiology, Biomarkers and Prevention.
Professor Joe L. of the Department of Epidemiology and Environmental Health at the University of Buffalo. “Puerto Rico gets a lot of sunlight throughout the year and people have a lot of skin color,” Frodenheim said. He added that some evidence suggests that exposure to the sun reduces the risk of breast cancer.
Frodenheim further explained that one phase of this is associated with the internal production of vitamin D in the body under sunlight. He said that sunlight is helpful for the body in many ways. These include inflammation, obesity and its effect on the circadian system, i.e. the body’s internal clock. In recent times, it has been advised to avoid sunlight to prevent skin cancer, but it is beneficial to protect yourself from the sun and to sit in the sun.
What did the study find?
Previous studies on sunlight and breast cancer were conducted in places where the change in ultraviolet radiation according to the season was minimal. But in Puerto Rico, people who go outdoors are exposed to high levels of ultraviolet radiation.
Cruz M., professor of epidemiology at the University of Puerto Rico and the first author of the research. Nazarios said the study found similar results on different parameters. He added that women who spend more time in the sun have a lower risk of breast cancer. Similarly, participants whose skin color was darker had less exposure to the estrogen receptor.
