I think there's a bit of confusion here. A biopsy usually means removal of a small sample of whatever the suspect lump, growth etc is e.g. a small section of the mole or a small sample of tissue from a growth in the body. It's the doctor/surgeon who takes the biopsy then the pathologist examines the biopsied tissue microscopically.
What I was saying was that I had never had a biopsy done, the entire mole was removed in order to be examined by the pathologist, rather than a small biopsied section. I wasn't suggesting for a minute that anyone could make a diagnosis simply by looking at a mole.
