Therefore,
90 % people have this:
Skin cancers, trigger, cancer cells and immunity … Nevertheless, A new American scientific study questions everything. In addition, A virus that the majority of us have on the skin could be able to cause skin cancer in. Similarly, just a few months. Therefore, Explanations.
Long considered to be cancer only linked to age. Therefore, exposure to the sun, the skin cancer today affects an increasingly young audience. In addition, In France, the figures are clear: the skin cancers are increasing sharplyespecially among under 50. In addition, Melanoma. For example, basal carcinoma or even epidermoid carcinoma (also called spinocellular carcinoma), forms of skin cancer are varied, sometimes discreet, often formidable. Moreover, Too much sun, tanning cabins, clear skin, family history … Risk factors are well known. Moreover, What we know less. however, is that these cancers can hide behind tiny signs: A crust that 90 % people have this does not leave, a pink task that spreads, a grain of beauty that changes shape, a lesion that always returns to the same place.
Today, science helps us to better understand how cells in our skin become cancerous. Consequently, And recent discoveries change the situation. Consequently, At the origin of skin cancerthere is often an accumulation of damage caused by UVespecially those of soleil. Moreover, Artificial UV cabins. These rays gradually deteriorate the DNA of our skin cells. But some people develop aggressive skin cancer even though they have no risk factor obvious. And this is where the researchers come in: by digging new tracks. they begin to lift the veil on a new culpritmuch more common than we imagined. This isA current virus, which may already live on our skin… Without being realized.
Skin cancer: a virus that everyone has on the skin (or almost) in question? – 90 % people have this
The 90 % people have this virus in question? Beta-HPV, a variant of human papillomavirusreports NBC News. Unlike its cousin, the alpha-hpv, known to cause cancers of the cervix or throat, the beta-hpv is discreet. He lives on the skinoften without making waves. Moreover. according to researchers from the National Institutes of Health (NIH), approximately 90 % of the population would carry this virus without even knowing it. But in some people, it can turn into real danger. This is revealed by a study published in the New England Journal of Medicine. “We squeeze with hands and attract these viruses, but if our immune system works well, everything is fine,” said Dr. Andrea Lisco, a researcher at Niaid. Issue : When our immunity is weakened, the virus can take over.
The click of this discovery? A 34 -year -old patient with tenacious skin cancer, suffering from 43 tumors on the skin. Despite operations and immunotherapy, his 90 % people have this spinocellular carcinomas (his tumors) were constantly returning, especially on the face, hands and legs. Its immune system, weakened by a genetic disease, could not control the beta-hpv virus. “The virus has multiplied uncontrolled, it ended up integrating into the DNA of its skin cells,” explains Dr. Lisco. Result: cells have become cancerous. To save it, doctors decided to replace its immune system with a stem cell transplant. Three years later, no more cancer or HPV infection. A world first.

An invisible mechanism… which can evolve in skin cancer in a few months
What this study 90 % people have this reveals is that the bêta-hpv is not only a passenger virus or a sun cofactor. He can alone cause skin cancer, infiltrating cell DNA And by diverting their functioning. And this process can be fast. Very fast. “The virus produced viral proteins inside the tumor”explains Andrea Lisco. In other words, the virus literally piloted cancer from the inside: a real upheaval in understanding skin carcinoma. So far, we thought that beta-hpv played an indirect role. We now know that he can, under certain conditions, be the main instigator. A capital advance for all immunocompromised people.
This discovery could Change our way of detecting, treating, and preventing certain skin cancers. For them immunocompromised people – Whether they are rare diseases. immunosuppressive treatments or transplants – the beta-hpv becomes a risk factor to take seriously“This suggests that there could be other people with aggressive forms of skin cancer linked to an immune 90 % people have this defect, and who could benefit from treatments targeting the immune system,” concludes Andrea Lisco. What encourage increased vigilance, but also the hope of more personalized solutions. Waiting for, Protecting your skin from the sun remains an essential reflex, especially summer. And in the future, perhaps it will also be necessary to closer to this virus that we thought harmless …
