Tel Aviv University researchers claim to have made a massive breakthrough in skin cancer research.

Until now, a big question faced by cancer researchers has been: How and why does melanoma, or skin cancer, become aggressive and deadly?

Dr. Carmit Levy of the department of Human Molecular Genetics and Biochemistry at Tel Aviv University’s Sackler School of Medicine explains that fat cells play a big role in the progression of the disease.

Questions remain, but the new findings and therapies tested are a basis for the development of improved drugs to halt the spread of melanoma.
