Here is the report from the recent meeting in the USA:
March 23, 2012 (San Diego, California) — Contrary to expectations, a reduction in dietary fat was not associated with a decreased risk for skin cancer, researchers reported here at the American Academy of Dermatology 70th Annual Meeting.
“Our findings were unexpected as they contradicted our hypothesis that a low-fat diet would decrease the risk of nonmelanoma skin cancer [NMSC] and melanoma, which we did not see in the overall analysis,” presenter Christina Gamba, a fourth-year medical student at Stanford University School of Medicine in Palo Alto, California, told Medscape Medical News.
However, a subanalysis of the findings suggests that an even lower fat intake than was studied might indeed be protective.
“We did see a small signal in the women with a healthier baseline diet who were assigned to a low-fat diet,” she said.
