Growth rate of BCC

Bryan K. Chen, MD answers: How fast does basal cell carcinoma grow?

From what I have read, basal cell carcinoma (BCC) tends to be slow growing. What exactly does that mean? I am 43 years old and have a BCC located just below my nose and scheduled for Mohs surgery on Tuesday. I have had the BCC for at least 5 years, probably longer.

My surgeon tells me that there is no way to know how much tissue will be removed until surgery. Immediately following the Mohs surgery, I will see a plastic surgeon to repair the wound. My bcc is pink slightly elevated with a rolled border and a crusted indentation in the center. When i went to the dermatologist, he knew right away just from looking at it that it was a BCC, biopsy confirmed. Do they grow at a certain rate? I just want to be prepared. Any information will be helpful.

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.
