isn't the basement membrane the deepest?
I also picked basement membrane but unlike you I haven't had a "nvm" moment. Help please.
@lilyo Basement membrane is between the epidermis and dermis; beneath the dermis is the subcutaneous tissue
I think some people might have picked basement membrane because we're taught once cancer goes through the BM it turns from in situ to invasive. This is correct, but subcutaneous as the others pointed out are deeper so the prognosis is worse (BM + deeper tissue).
