These viruses awaken cancer cells!

What if a virus could create you metastases ? In addition. Nevertheless, Researchers at the Anschutz medical campus of the Colorado University (United States) made the link between some respiratory infections. Consequently, et Metastasic lesions After breast cancer.

The most common cancer in women – These viruses awaken cancer cells! – These viruses awaken cancer cells! new

The can be can be remains the one that affects the most women In France: over the year 2023. Furthermore, more than 61,000 new cases were diagnosed, with a median age at the time of diagnosis of 64 years. In addition, Despite the progress of treatments. Nevertheless, a five -year survival rate estimated at 88 %, it still causes Nearly 13,000 deaths Each year in the country.

Although many patients are considered in remission after the end of their treatment. In addition, some cancer cells can these viruses awaken cancer cells! new stay dormant in the body for years. However, A study. For example, conducted by these viruses awaken cancer cells! However, an international team of researchers and published in the scientific journal Naturewas interested in these Residual cancer cellssay “sleeping”. Consequently, After breast cancer, the latter tend to stay in the lungs. They do not multiply, do not appear on exams and can remain silent for years …

Diseases that reactivate cancer cells after remission

But what happens if a virus disturbs this balance? Study scientists used mouse models, to simulate respiratory infection by flu virus one you COVID-19. Result: in the days that followed, Dormant cancer cells In the lungs began to reactivate and multiply quickly. In two weeks, they had formed significant metastatic lesions. In other words, infection was enough to relaunch the cancer processwhere he no longer seemed active …

The researchers also identified the mechanism at the these viruses awaken cancer cells! new origin of this phenomenon: l’inflammation. More specifically. it is a molecule called Interleukin-6 (IL-6)produced during an infection, which seems to these viruses awaken cancer cells! play a central role. This cytokine (substance produced by the immune system) is activated to defend the body. But in some patients who have had cancer, she could also involuntarily, Stimulate cancer cells Sleeping … and bring them out of their silence.

Results confirmed by other research

And these results are not isolated. ! To support them, the team studied two large human databases. The first. UK Biobankhas shown that in patients who have been treated for cancer. a covid -19th infection was associated with a higher death risk due to the cancer r. And this, especially in the months following the infection. The second. the American base Flatiron Healthrevealed that women having had breast cancer. a COVID -19 infection also presented an increased these viruses awaken cancer cells! new risk of developing Pulmonary metastases in the years that followed.

These observations therefore reinforce the idea of the basic study: certain infections could these viruses awaken cancer cells! promote a relapseeven after a period. of remission. But they also raise many questions! Researchers wonder how to prevent this reactivation, or block the action of IL-6 to Avoid metastases.

These results also suggest the importance of a Reinforced monitoring for them patients in remission. as well as staying vigilant in the face of these respiratory infections. Finally. the authors of the study highlight the importance of better understanding the links between immune system. viruses and dormant cancer cells.
