Basal cell skin cancers vary in their growth rates - typically no faster than 2-3 mm over 2-3 months. Local destruction and invasion is what we worry about with BCC, as metastasis of this tumor is very rare. It is common for patients to present with these growths that appear to have been present for years, apparently unchanged. The visible portion of the tumor, however, does not always give an accurate picture of the entire size of the tumor. It may be the "tip of the iceberg" so to speak. Sounds like you are getting the appropriate skin-sparing procedure, Mohs surgery.
