Israeli researchers reach ‘breakthrough’ in fight against skin cancer
Melanoma may quietly build its own escape routes before it ever becomes dangerous, according to researchers at Tel Aviv University and Sheba Medical Center. They discovered that while the cancer is still confined to the skin’s outer layer, it releases tiny pigment-carrying vesicles called melanosomes that slip into the deeper dermis and coax lymph vessels to grow — essentially paving roads the tumor will later travel to spread. Because melanoma isn’t life-threatening until it leaves the skin, the team believes a vaccine could train the immune system to intercept those melanosomes first. With about 325,000 people diagnosed worldwide each year, this early-stage target could open a hopeful new chapter in shifting cancer treatment from reactive to preventive.
