Physician here. As others have said, Usually through scans and different tools but visually, youre right, its often a "lump" the architecture of tumours are almost always off from normal tissue. Its just rapidly dividing cells going any which way so more often its just a lump. There is often tumour spreading away from that lump too which is harder to see so they cant just go by that of course.

A common skin cancer is melanoma, and those are made specifically from the pigment producing cells in the skin, so they would be hyper pigmented and often dark. Squamous cell and basal cell skin cancers can be any colour really.

Because those other categories have been well studied already and it doesnt work there either.

Funding is required to be listed by law... it takes no digging... no conflicts of interest and no further funding source listed means its funded internally by the university... your claims are totally made up from the fact that the author once did a study on a trial drug for that pharm company at some point in the past. You are aware trial funding gives zero money ti the researcher and its all to fund the trial costs as well. And that data is incredibly well documented to be for that specific trial alone. The only worry is if that trial is bias because the funders decide what studies are being done to some degree and can look at specific things which are more favourable to them (although thats harder to do in medicine with more restrictions in place).

Also if you think the director of the niaid directly decides who receives noh grants you also have no idea how these insittutions run.

You obviously have no clue on how medical research is conducted

If caught early possibly but thats absolutely not true once it gets going. I have type 2 diabetic patients admitted to hospital and literally not eating any food for days due to multiple factors. They still need insulin. That is the vast majority of type 2 diabetics i see.

In their heads, anyone who died of covid was misdiagnosed and died of something else... and anyone who died of anything else they say died of the vaccine. Its an easy lie to continue if you already assume the entire healthcare community is lying to you.

Ypu go to work i presume.. and other people srent like you amd spend time with people and get sick and infect you.

If you were really isolated you would never get sick.
