Discovery of how melanoma spreads to other organs in the body

Plazma Inferno!

In a landmark discovery, researchers at Tel Aviv University have unraveled the metastatic mechanism of melanoma, the most aggressive of all skin cancers.
According to a paper published today in the journal Nature Cell Biology, the scientists discovered that before spreading to other organs, a melanoma tumor sends out tiny vesicles containing molecules of microRNA. These induce morphological changes in the dermis in preparation for receiving and transporting the cancer cells. The researchers also found chemical substances that can stop the process and are therefore promising drug candidates.
Researchers say that the threat of melanoma is not in the initial tumor that appears on the skin, but rather in its metastasis -- in the tumor cells sent off to colonize in vital organs like the brain, lungs, liver and bones. The recent discovery of how the cancer spreads to distant organs will help us find ways to stop the process before the metastatic stage.
