Melanoma is the cause of most deaths related to skin cancer , being the most aggressive and whose incidence continues to increase. Now, a new study by scientists at the University of California, Los Angeles (USA) has shown that melanoma cells spread faster through the body like a tide of tiny spiders, due to ultraviolet rays. . The results of the study have been published in the journal Nature .
According to the researchers, this journey of cancer cells through the body also occurs outside the body , without ever entering the bloodstream, thanks to the effect produced by ultraviolet light on our skin.
This process was observed in a study with laboratory mice that had been genetically modified to develop melanoma. The researchers discovered that mice exposed to ultraviolet radiation suffered an acceleration of the expansion process of cancer cells , as well as the appearance of metastases in the lung. Mice not exposed to UV light did not undergo any changes.
The researchers affirm that the confirmation of this study can help the scientific community to find a solution that interferes with this process , since the danger of a manageable chronic disease such as skin cancer can become a disease with death sentence due to this extravascular migratory metastasis of cancer cells.
