I am not sure what you mean by has it spread. If SCC or a BCC is not treated it will spread either downward or length.

That is why surgeries like MOHS does a incision to see if they have removed and signs of cancer below and around the skin cancer. If not they come back and remove more tissue either under the area or expand the incision width or length.

Does this answer your question?

Do you have a good dermatologist. If you can't find your answers on MCC (and remember we are not medical professionals) you should make sure you asked your doctors who are treating you.
