The skin changes
In general, a basal cell carcinoma results in characteristic skin changes, which, however, only become apparent over a longer period of time, as this tumour usually grows rather slowly. In the initial stage, at the site where the basal cell carcinoma later becomes visible, there is often simply a circumscribed hardening (induration) of the skin or an initially inconspicuous small, often greyish nodule. There are, however, different types of basal cell carcinoma, which can sometimes look very different.
