The common sunscreen ingredient benzophenone-3, also known as oxybenzone or BP-3, can play a role in the development of mammary gland tumors, according to new research in mice.
“Our set of results suggest caution in using BP-3 and the need to dig deeper to understand what it can do in mammary glands and tumorigenesis,” says Richard Schwartz, professor in the microbiology and molecular genetics department at Michigan State University, who has been researching the interaction of diet and cancer cell growth and proliferation for more than 12 years.
