medical debt can be ignored for years

cancer can't

even if you can't afford it, it'll cost so much more to ignore it, if it really is cancer. i have no good answers for you except maybe try to get hooked up with a mutual aid group or start a crowd fund or talk to some extended family

if nothing else, go to a general practitioner and have them look at all the shit on your skin. in a mayo country theyll likely be pretty practiced at telling whether any of them need a dermatologists eye or whether theyre just the weird skin shit everyone has. there might also be free skin-check clinics around you. and getting a small surface lesion that hasnt invaded deeply cut off will not be cheap but wont be lifetime-of-debt territory

and if it is something more serious, there are clinical trials running all the time, and a lot of them are in practice more like access programs for established treatments (but with something new thrown on top) than they are guinea pig shit (theyre the sort of thing pretty much everyone with bad cancer should consider regardless of money)

UK here, out of interest as I don't really have perspective or experience on this, how much are they?
