As a preface, this isn't a comprehensive answer for everything. As MattDMo points out, some of the original answer was poor in it's presentation. In my update there's some supporting information to some expert testimonial, but this is mainly targeted at adult cases rather than pediatric cases, i.e. why would cardiac cancer be rare in an adult with no prior ...

Since your questions seems to be motivated by personal health protection, consider an alternate view, which is that not only is the sun's damage to the skin not "sufficient to warrant protection anytime I go outside or just for extended periods", but that lack of sufficient unblocked exposure to the sun may be, overall, even more harmful--not only for the ...

Because the website you link speaks of cancer, they probably go by the rule that a single exposure and even a single photon of UV may be sufficient to cause that one mutation in that one skin cell that will eventually lead to cancer. In the end, they are right, because mutagens (UV, cigarettes, radiation) do not follow typical toxicological rules. There is ...

Cancer cells generally lack the "safety mechanisms" or "check points" that prevent normal cells from replicating, and some of these mechanisms are also involved in ensuring that DNA replication proceeds without serious errors. Inactivating these safety mechanisms lets cancer to cells divide rapidly, but at the same time also causes their genome replication ...

Great question and in part, you are correct. However, you must also remember that this greatly depends on what genes have undergone mutation. In the case of cancer, it's usually either a gene that regulates cell proliferation rates, induces programmed cell death or helps to repair damaged DNA. When one (or all) of these genes is mutated, the cell ...

This is a good question and it gets to the most basic foundations of immunology. Your immune system is made to be flexible - able to adapt to almost any challenge. However, with so much flexibility comes the potential to generate immune cells that react against the 'self'. So, at the other extreme, the immune system needs to be limited. In order to meet ...

This study has received next to no media coverage. With RFR impacting so many people it makes me wonder, is this study valid? Well first of all, lets be clear: that is not a study. Its a review article, basically a paper that summarizes a series of studies published. The review itself isn't valid or invalid necessarily, it simply takes a series of ...
