What is an Acceptable Wait Time for Basal Cell Cancer Treatment on Ear?

While it would be ideal if the process was more streamlined and your Mohs surgeon wasn't booked out, this type of delay is not unusual. Basal cell skin cancers tend to be slow growing and this type of delay does not typically result in much change in garden variety skin cancer. If you notice any more rapid changes in your skin cancer, let your Mohs surgeon know.

While waiting 4 months to have your lesion treated is probably ok, it is not ideal.  And if you are a transplant patient or are immune suppressed, it should be done sooner.  As a patient, I wouldn't want to wait that long to have my cancer treated.  I would recommend taking the initiative and looking on the website for the American College of Mohs Surgery and you can simply type in your zip code and see which Mohs trained physicians are near you.  You might even go for a consultation or two prior to your surgery to see which doctor you like best so you can make an informed decision.   

Generally speaking basal cell cancers on the ear are treated by Mohs surgery as the first line therapy. Waiting 1-2 months is ok unless it is a very large tumor or there is something particularly aggressive about the basal cell cancer (ie aggressive pathology, rapid growth, etc). If you have a concern ask your Mohs surgeon if they can fit you in if someone cancels or if a sooner opening comes up.
