The article is reliable and trustworthy due to its use of multiple sources from peer-reviewed journals and reputable organizations such as the National Cancer Institute and the European Molecular Biology Organization (EMBO). The article also provides citations for each source used, which adds to its credibility. Additionally, the article does not appear to be biased or one-sided; it presents both sides of the argument equally by exploring counterarguments and providing evidence for claims made. Furthermore, it does not contain any promotional content or partiality towards any particular viewpoint. However, there are some missing points of consideration that could have been explored further such as potential risks associated with immunosenescence and how it affects cancer development. Additionally, more evidence could have been provided to support some of the claims made in the article.
