The description of your fact check is accurate and summarized your source well, but it would be better and more concise if the title matches your claim. Your claim title seemed to be completely opposite from the source's main idea, since the fact is that "microwaves do not cause cancer because the radiation they emit is non-ionizing". The source is reliable, it's not only published from the National Library of Medicine, but also written by professionals in the health and science area relating to radiations.
