> Yet despite what we know about prevention, skin cancer remains the most commonly diagnosed cancer in the United States.<p>> All of the active ingredients in the study noted above were absorbed in levels substantially higher than the 0.5 ng/mL threshold value cited in the proposed rule. However, without further testing, FDA does not know what levels of absorption can be considered safe.<p>Most common? It's also the easiest to see / identify. In addition, perhaps due to more and better testing, many types of cancer are increasing. Screenings aside, perhaps we have environmental issues (i.e., water, air, diet, etc.)?<p>To that point, do they not hear their own mixed signals? That is, "...despite what we know about prevention..." later followed by "...FDA does not know what levels of absorption can be considered safe."<p>Effectively: "Here stop skin cancer, but we have no idea what other harm(s) it might be doing."<p>Don't we have these Federal agencies to prevent such disconnects? Is this the same mindset that went into the Covid approvals and monitoring? It is the same agency, with the same history.
