BCC or SCC - What's the difference?
When patients come to me holding a pathology report, the word “cancer” has already triggered fear. At that stage, most of them don’t really read what’s written - they just see the word and stop.
So let’s talk about the two most common types of tumors I operate on: BCC and SCC.
Yes - both are skin cancers.
No - they are not the same.
First: BCC — Basal Cell Carcinoma
This is by far the most common tumor. About 8 out of 10 cases I see are BCC.It is a slow‑growing tumor. It almost never spreads to other organs.
But - it does invade deeply.
A small BCC on the nose can, over years, reach the cartilage.
On the eyelid - it can extend into the eye socket and even into nerves.In some cases, this tumor can infiltrate surrounding tissue with almost no external sign other than a slight change in skin color or texture.
Classic sign: A shiny pink sore that keeps returning, bleeds, doesn’t heal, and slowly grows.
Sometimes it can be brown or black in parts, and it often appears in places where the patient assumes it came from trauma (glasses, scratches, etc.).
Second: SCC — Squamous Cell Carcinoma
This tumor is less common and behaves differently.
SCC can spread - to lymph nodes, and in rare cases to distant organs.Not always, not with high probability, but this is a major difference from BCC.
In some cases, this tumor is dangerous and even life‑threatening.
There are several subtypes - some more aggressive, some less, some deep, some superficial.
Classic sign: A rough, scaly lesion - sometimes ulcerated, sometimes fleshy and nodular - usually on sun‑exposed areas: face, ears, lips, hands.
Why Mohs Surgery Is the Preferred Treatment for Both?
Because in Mohs surgery, unlike standard excision, we examine all tumor margins immediately under the microscope.
We don’t take “wide margins” as a safety measure - we take exactly what is needed, confirm that everything is clear, and then close.
Result: Maximum cure rates with minimal damage to healthy tissue.
Bottom Line
For BCC - it’s important to treat, maybe slightly less urgent, but we do not wait.
For SCC - we definitely do not wait. Treatment should be done promptly and thoroughly.
If you received a report with one of these names - contact us.
We’ll explain exactly what’s going on and what the next step is.
