Is there such thing as a DIY biopsy?

Or you could just use one of these

Great but these aren't on the market yet are they

This is the kind of device that will get repressed by the medical authorities, its an existential threat to them.

I'm guessing blood blister underneath the more, I can see another one nearby.

How long has it been like that?
Was it getting irritated by what you wear?
What part of your chest is it?
How is your hygiene?

Have a close look at this mole, does it have a hair growing out of it, even if it is a tiny tiny one?

Moles with hair do not turn into malignant tumours such as cancer.

Nevertheless, I'd suggest to show it to an oncologist.

I've had the mole forever but it just got funny in the last few days, it's coming a bit down since the post though. It's right in the middle of my sternum on both axes. My hygeine is good but I should note my laptop battery sits right over the area for hours a day.

No hair, that's a really good one though I didn't know that.

Thanks a lot, I can't afford an oncologist so this is all especially appreciated.

I am glad the inflammation is less.
The mole must have got irritated from constant contact with the battery.

But better be safe than sorry. Go and see a professional.

Is there no state "provided" dermatologist where you live?

Otherwise, A.D.D.MEN idea seems doable, no?
