From what I've heard, a tumor looks/feels different from normal tissue. Dr. Sandra Lee (aka Dr Pimple Popper) has a few videos on lipomas (a non-cancerous tumor) and I believe at least one has an explanation.
I don't know the answer to your question regarding skin cancers, with the exception of melanoma, which is a cancer of the pigment-producing cells in your skin. This makes it very easy to differentiate on lighter-skinned folks as it is physically darker than the surrounding normal skin.
