I know that humans are weird and different, and all of us have weird lumps and spots that show up on a scan. My proposal is to just track each spot and keep an eye on them over a period of months or years. We already do this with mole mapping, and MRI scans allow us to do "mole mapping" for our entire body.
From an interview about mole mapping [1]:
> Dr. Curtis: So, generally, what I tell patients is if they have a lot of moles, they should get mole mapped, or if they even have a lot of funny looking moles to them. They might not have a ton, but at the same time, they still might have enough that they are curious about them and they're hard to track, if they're hard to know if they're new or changing.
> Interviewer: Let's talk about the benefits of having this procedure done because there are a lot of them. First and foremost, it can save lives.
> Dr. Curtis: Yes, it can. It can save lives in the way that we can find melanoma earlier and thinner when it is the absolute most survivable.
> Interviewer: And what are some of the other benefits as well?
> Dr. Curtis: So you can catch new moles that could be just benign, not changing, that are not melanoma, which are important to know about. You can also tell if your moles are going away. As you get older some of your moles do go away and it can track that. So it gives you peace of mind. And it can reduce the number of biopsies as well on patients.
