Researchers decipher the mechanism that enables skin cancer to metastasize to the brain - and inhibited its spread by 80%

Tel Aviv University researchers discovered that skin cancer cells interact with astrocytes in the brain, promoting metastasis. By inhibiting this interaction using existing treatments, they delayed the spread of melanoma to the brain by 60-80%. This breakthrough has implications for treating advanced-stage melanoma.
