Squamous Cell Carcinoma Treatments

Most squamous cell carcinomas may be treated by one of the following methods. More healthy tissue around the lesion is removed than for basal cell carcinomas because of the potential of squamous cell carcinomas to spread. Nearby lymph nodes are also examined carefully. The choice of treatment is influenced by:

* size, location, grade, and type of tumour
* whether the tumour is primary or is recurring
* person’s age and health
* people with organ transplants are at a high risk of aggressive squamous cell carcinoma, which is considered in their treatment plan
* availability of the treatment

Surgery (Wide Excision)

# used for:
- most small lesions that are less than 2 cm
- superficial or SCC that has not spread
- verrucous carcinomas (slow growing and less aggressive)
- tumours that have previously been treated with radiation therapy
- lesions on the eyelid, forehead, scalp, lip, penis, vulva and anus

Mohs Micrographic Surgery

* used for all types of squamous cell cancer
* commonly used for:
- areas that are at high risk of recurrence (eyelids, nose, ears, forehead, scalp), as well as areas that have - already recurred
- areas where it is important to keep function and appearance
- lesions that are larger than 2 cm, and lesions with poorly defined borders
- aggressive tumours, and invasive lesions that have spread to nerves, cartilage or bone
- tumours that have been left untreated for a long time
- lesions that had not been completely removed with prior surgery it involves a meticulous study of tissues removed by a  pathologist at the time of surgery

Radiation Therapy

* used after surgery for:
- elderly individuals
- ensuring cancer free margins
- treatment of involved lymph nodes
- squamous cell carcinoma that has recurred after surgery
- to relieve or control the symptoms of very large tumours
- for people who are unwilling or unable to undergo surgery
- tumours on the eyelid, cheek, earlobe and nose not used for verrucous carcinomas (slow growing and less aggressive)

Chemotherapy

* systemic chemotherapy is used for squamous cell cancer that has spread to other parts of the body
* drugs used most often in chemotherapy:
- cisplatin
- doxorubicin
- bleomycin

Curettage And Electrodesiccation (C & E)

used for
- small areas that are less than 2 cm
- lesions that haven’t spread
- squamous cell carcinoma with distinct margins in Actinic Keratosis should not be used for:

- larger lesions that are greater than 2 cm
- recurrent tumours
- aggressive squamous cell carcinoma
- lesions with poorly defined borders
- hairy areas like the underarms, scalp, and the pubic area
- areas where it is important to keep function and appearance uncommonly used

Skin Tags and Seborrheic Keratoses

Nuisances You don’t have to put up with. As time goes on, we all acquire tiny bits of extra skin called skin tags. These can range in size from 1-10 mm, and are flesh colored or brown.

Skin tags can be found on any part of the body, but are most common on the eyelids and neck, and in the armpits and groin, and under the breasts.  While skin tags are benign they can be annoying if they become irritating or rub on sporting equipment, and skin tags can interfere with shaving and can detract from one’s appearance and self-image.

Fortunately, we don’t have to put up with skin tags. These little annoyances can be easily removed in an office visit with little or no discomfort. Skin tags can almost always be removed without needing stitches, and the treated areas usually have healed completely in a week or two.

The cost of removing skin tags is quite reasonable - ranging from about $80 for a few tiny ones to about $200 for a larger number scattered over several areas.

Seborrheic keratoses are firm flat or raised, sometimes scaly or crusty flesh-colored, brown or black “barnacles” which accumulate (usually on the face and trunk) as time goes on. Some people start to develop seborrheic keratoses in their thirties, and most people have at least a few by the time they are sixty.

Seborrheic keratoses are usually just a nuisance, but - like skin tags — they can rub on clothing and equipment, and their appearance can sometimes be so distressing that they interfere with choice of clothing, sports like swimming, and intimacy.  Because seborrheic keratoses grow above the skin (but not down into the skin) they can be easily scraped off, and the treated areas heal up nicely within a few weeks. Sometimes the healed area remains pink for a few months after the seborrheic keratosis is removed.

The cost of removing seborrheic keratoses is similar to that for removal of skin tags: about $80 for one or two, with the cost gradually increasing depending on the number and size of seborrheic keratoses to be removed.

The cost of removing skin tags and seborrheic keratoses is a tax-deductible medical expense, just like things like dental bills.  So, if you are annoyed by skin tags or seborrheic keratoses you can be confident that it is simple and inexpensive to rid yourself of these nuisances.
