Basal Cell Carcinoma

Your biopsy showed a basal cell carcinoma.  A basal cell carcinoma is a very common type of skin cancer, but it usually is not very aggressive.  It may grow locally but it almost never spreads inside the body.  If left untreated, it will grow larger and deeper over time.  This can cause pain, bleeding, and tissue destruction.  Therefore, it needs to be removed.

When possible, basal cell carcinoma is usually treated with surgical removal. If you have an early basal cell carcinoma, this can often be performed in your dermatologist’s office while you remain awake. The following explains the types of surgical removal used to treat basal cell carcinoma, along with other treatment options.

Surgical removal: Three types of surgical removal are used to treat basal cell carcinoma. The type of surgical removal you receive depends largely on the type of basal cell carcinoma you have, where it’s located, and how deep it goes.

Here’s what involved with each type of surgical removal:


In an excision, the area around the skin cancer is numbed like in a skin biopsy with an injection of local anesthesia.

Then, a margin of normal-appearing skin around the area is cut out and the wound is closed with stitches.

In all cases, the tissue removed will be sent to the pathology lab and analyzed to make sure the margins are clear and the spot has been removed.

There is generally little to no wound care required at home.  Stitches usually stay in between 10-14 days on the trunk and extremities, depending on the site of the surgery.

Activity like vigorous exercise, tennis, or golf may be limited during that time until stitches come out.  In addition, there can be no underwater submersion until the stitches have been removed.  This means no swimming or baths until then.  Showering after the pressure bandage has been removed, 48 hours after surgery, is fine.

The risks of the procedure are small, but include bleeding, low risk of infection, further required surgery, cancer recurrence, and a scar.  The recurrence rate is about 8% for skin cancer excisions.

Mohs Surgery

On some areas of the body, such as an eyelid or your nose, removing an area of normal-looking skin along with the cancer would cause problems. There’s not enough skin in these areas.

Mohs surgery eliminates the need to remove an area of normal-looking skin. This is possible because the surgeon can see where the cancer stops during the surgery.

Electrodesiccation and Curettage:

In an electrodessication and curettage, or destruction, the wound is basically numbed like a biopsy with an injection of local anesthesia. This surgery is usually performed only when basal cell carcinoma develops on the trunk, an arm, or a leg.

A tool called a curette is used to scrape off the cancer. An electric current in a device called a hyfrecator is used to cauterize the base. The wound heals on its own in four to twelve weeks, depending on the location. For example, it may take about four weeks to heal on the arm and three months on the lower leg, although it may be sooner.  The wound heals with a circular pink to white scar.

There is nothing further sent to the laboratory. The area is monitored for recurrence by the doctor.

Activity under water, like in the pool or ocean, is not recommended during the extended healing time. The procedure requires daily wound care and dressings at home. The risks of the procedure are small and include bleeding, low risk of infection, scar, and recurrence of the skin cancer.  The recurrence rate is about 10% for this procedure.

Other options at times include radiation therapy, which is generally not recommended as first-line therapy, or uncommonly topical therapy for specific cases of superficial basal cell carcinoma in select cases. Superficial radiation therapy (SRT) is not recommended by us at Florida Dermatology Specialists.
