Sorry to hear that. It can be shocking news. If the pathology report confirms basal cell carcinoma (BCC) then it is probably very treatable. Your doctor seemed pretty confident it was BCC. Is this is the first time you've had one?
The good news is that BCC is common enough that doctors know how to treat it.
Wikipedia has a
lengthy page on BCC. Don't be scared by reading it, it covers all forms from early to advanced metastatic stages. I offer that link because knowledge is power, but be warned that some of the photos may not go nicely with lunch.
Another piece of good news is that last winter a new drug,
Vismodegib (trade name Erivedge made by Genentech, Inc.) was approved by the FDA for cases of advanced metastatic BCC. It's the first drug that targets a biological signaling mechanism known to be involved in BCC. The clinical trials of this drug in BCC were very successful. If the pathology report confirms this is BCC and if this is your first one, you are very far, if ever, from needing this drug. I'm just letting you know there is some recent progress.
