For me?

If I could have daily full 3d body scans, and time lapse healing, track injury progress, visualize and correlate food and exercise.

And all I have to do is chill out about known benign cysts and tumors.

Yes I think it will help. I would take that trade off.

I already can feel a few cysts that have been with me for a long time, docs said I was fine, so I've already been through the stressful initiation of benign lumps.

You won’t know they are benign unless you plan on a biopsy or surgery for every finding. It’s exactly this reason why we only regularly scan people that have say, known cancer.

They'll know whether they're getting bigger or not. Pretty much the same for if you have a lump just under your skin that you can see and feel but this would allow you to see the ones further inside. So you just have to take the same attitude and advice towards them that a doctor would give you about the surface level lumps. What's the difference?

And for what? Is it just morbid curiosity or is there something you plan to do with that information.

It’s right there in their second line

But from what this says, it's not accurate enough to determine benign vs cancerous lumps
