Skin Cancer Treatments

The choice of skin cancer treatment is based on your preferences, and your specific circumstances. Once you receive a skin cancer diagnosis the choice of treatments will depend on the type of cancer, the size, location on the body and depth of the tumor and your preferences. Other considerations are your age, health, and the effect of the treatment on your appearance. All treatments can be performed in our state-of-the-art facility Tucson, Arizona dermatology office under local anesthesia.

Surgical skin cancer treatments

Surgery is a common treatment for skin cancers. There are various procedures available for non-melanoma skin cancers, and special options for melanoma skin cancer.

Excisions

A surgical excision is the surgical removal of a skin lesion and a margin of healthy tissue around the tumor–reword. Under local anesthesia, the tumor is removed with a surgical knife along with a wide margin of healthy skin, and the wound is closed with stitches. The excised tissue is examined at a lab by a pathologist to assure that all cancerous cells have been removed. If the lab reports that cancer cells still exist, a second procedure will be necessary to reduce the risk of recurrence. Cure rates are close to 95%,. Mohs surgery is a better option for skin cancers located in places like the face where it is important to save as much healthy tissue as possible.

Curettage and Electrodessication

Curettage and electrodessication are a good treatment for small superficial basal cell and squamous cell tumors. Under local anesthesia, the growth is scraped off and then burned with an electrocautery needle to destroy any remaining cancer cells. It will leave a circular whitish scar slightly larger than the size of the lesion.

Mohs micrographic surgery

Mohs micographic surgery is recommended for the removal of melanoma and non-melanoma skin cancers. Mohs surgery reduces the risk of recurrence. Mohs surgery is recommended when:

  • there is a significant risk the cancer can spread or reoccur
  • it is difficult to determine the extent of the cancer
  • when the tumor is an area where excision can cause disfiguration, and
  • when the goal is to save as much healthy skin as possible such as when the tumor is on the face, eyes, lips and nose.

The procedure involves the removal of thin layers of the tumor. Each layer is examined under a microscope by Dr. Farhang to see if any cancer cells remain. This is repeated until a sample is free of cancer cells. While Mohs surgery can take several hours, the result is the preservation of healthy skin, the smallest scar achievable, reconstructive surgery when needed and the best cure rate possible.

Mohs surgery requires specialized training. Dr. Sheila Farhang is a board-certified dermatologist and fellowship trained Mohs surgeon.

Nonsurgical treatments

Local treatments are designed to destroy very superficial tumors but have lower cure rates. Dr. Farhang will always give options and her best recommendations.

Cryotherapy

Cryotherapy involves freezing the tumor when it is localized and has not spread. It is also commonly used for precancerous conditions like actinic keratosis. Depending on the patient, the type of skin cancer, and how early it is diagnosed, cryotherapy can also be used to treat very superficial non-melanoma cancer.

The tumor is frozen using liquid nitrogen which kills the cancer cells. Repeated freezing may be necessary. 20-50% of patients experience side effects including pain, blisters, and the potential for hypo-pigmentation and scarring. An additional disadvantage is the inability to assure that all cancerous tissues have been removed.

Topical chemotherapy

Topical therapies are reserved for low-risk superficial tumors that donโ€™t extend deep into the skin. The advantages of PDT and topical drugs are that they do not cause scarring and can treat wide areas of superficial skin cancer.

A significant disadvantage of these topical treatments is the inability to assure that all cancerous cells have been removed, because these treatments are limited in that they cannot reach deep in the skin. In addition, topical photodynamic therapy (PDT) causes pain during the procedure and inflammation including redness, erosions, pustules and crusts that last for 1-2 weeks.

Radiation

When the tumor is unable to be removed surgically, the tumor is large or in an area difficult to reach, or the patient has other medical problems and cannot undergo surgery, radiation therapy may be recommended. Radiation therapy can cure small tumors. It may be combined with surgery to assure that all cancer cells have been killed.

Melanoma Treatment

Lymph node dissection

Melanoma first spreads to nearby lymph nodes. Lymph node dissection is a surgical procedure to remove lymph nodes near a melanoma that are abnormal.

Other melanoma treatments include Immunotherapy, targeted drug therapy, chemotherapy and radiation. If a melanoma is deep or metastasized Dr. Farhang will coordinate with your oncologists for optimal patient care.

When you have been diagnosed with skin cancer, you want a surgeon who will assure you receive the best treatment possible for you. Dr. Farhang is a board-certified dermatologist and Mohs surgeon. Dr. Farhang is considered a skin cancer expert having written a text book chapter on the topic as well as sub-investigator researcher in a skin cancer chemo clinic trial.
