The melanin that is present in higher concentrations in ethnic skin tones provides a degree of natural protection from the sun. While the most serious type of skin cancer - melanoma - is less likely to occur in African Americans and other individuals with dark complexions, it is most often fatal when it does develop in these populations.
Now, a team of researchers at Penn State College of Medicine have developed a topical treatment which they believe could be effective at preventing melanoma.
The ointment, called ISC-4, works by inhibiting a certain protein that has been associated with the development of serious skin cancers.
The "addition of agents such as ISC-4 to sunscreens, body lotions or creams could have a profound impact on this market for preventing melanoma," said lead researcher Gavin Robertson, Ph.D.
While the study authors report that further research on ISC-4 is needed before it can be marketed and sold, they said that natural compounds found in cruciferous vegetables - like broccoli and Brussels sprouts - also help to inhibit the cancer-causing protein.
In the meantime, African Americans should be sure to wear skin care products for black women that contain sunscreen.
