A Really Important Melanoma Breakthrough Just Rocked the Science World:
"A major scientific discovery has been made that will affect future treatment options for melanoma — the most aggressive of all skin cancers.
Researchers from Tel Aviv University have determined that a melanoma tumor sends out vesicles, small structures enclosed by a membrane, that contain molecules that cause changes in the dermis — the inner layer of the skin — and allow the cancer to spread to other vital organs, including the brain, lungs, liver, and bones.
Understanding this process means that investigators can finally begin to stop the cancer before it reaches the metastatic stage.
For years, scientists have understood that melanoma forms in the epidermis, the outer layer of the skin.
At this stage, the cancer is unable to enter the bloodstream because it doesn’t have access to blood vessels.
Yet it somehow can find a way to break the barrier to connect with the numerous blood vessels running through the dermis..."
