At the West Dermatology & Skin Cancer Center, we specialize in screening, diagnosing, and treating skin cancer. We know that this type of cancer raises a lot of questions and concerns, so we are dedicated to treating and helping you resume a normal life by offering the most advanced treatments possible in San Diego.
Skin cancer is the most common form of cancer in the U.S., and although it can be effectively treated when caught early, you should not ignore mysterious skin imperfections, bumps, lesions, and discolorations that develop. The causes and symptoms vary, so a true evaluation of any skin irregularity especially one that is changing must be done by a board certified dermatologist, especially one who specializes in skin cancer.
Causes and Risk Factors of Skin Cancer
Skin cancer results from an accumulation of damage from the sun’s ultraviolet (UV) radiation. Additional factors that can contribute to the disease include a compromised immune system or exposure to harmful substances such as toxins or radiation.
Other risks include:
- Skin cancer history in the family
- Numerous sunburns
- Fair skin
- Moles or precancerous skin lesions (e.g., actinic keratosis)
- Climates that are sunny
- High-altitude locations
- Recreational outdoor activities
- Professional outdoor activities
More Than One Type of Skin Cancer
Skin cancer develops due to a mutation of skin cell DNA in the epidermis or the top layer of the skin.
There are three major types to be aware of:
Squamous cell carcinoma (SCC)
This develops in the squamous cells just under the surface of the skin, particularly in areas commonly exposed to the sun, such as the face, arms, hands, legs or ears. SCC is distinguished by a flat, crusted lesion or a scaly, firm reddish skin nodule that may bleed.
Basal cell carcinoma (BCC)
This is the most common type, which develops in the basal cell layer just beneath the squamous cells. BCC usually forms in areas prone to sun exposure such as the face, neck, nose, or ears, and it often appears as a bump with a waxy appearance or a flat lesion with a scar-like appearance which may ulcerate.
The deadliest type, it forms in cells called melanocytes, which are found in the bottom layer of the epidermis. A melanoma is different from the other two cancers because it usually forms in areas that don’t see the sun. It manifests as a multi-colored black, blue, red, tan and/or brown spot, a mole that bleeds, a change in color or an abnormally-shaped lesion.
Skin Cancer Screening and Diagnosis
The National Cancer Institute states that 20 percent of Americans and over 59% who live in the Southern USA—regardless of skin color, skin type, ethnicity, or race—will have skin cancer at some point. For those with symptoms, a skin cancer screening by a medical professional at our Skin Cancer Center can detect the disease early enough for an easy successful treatment.
In fact, a screening is useful for those lacking symptoms yet, due to risk factors such as frequent sun exposure, are at a higher risk of skin cancer.
Skin Cancer Treatment Options
Once skin cancer has been diagnosed, various types of treatments are available, but which treatment is chosen depends on both cancer type and the patient’s overall health.
Common treatment options include the following:
Mohs surgery – A precise procedure known as Mohs micrographic surgery has been in practice for decades and remains the most common treatment method because the cure rate is very high.
Excision – The targeted growth is removed with a sharp surgical razor in one of two ways: excisional biopsy (full removal) and shave excision (a less invasive method for removal of superficial lesions).
Cryotherapy – Super-cooled liquid nitrogen, between -346° F and -320° F, is used to destroy diseased cells without damaging the adjacent tissue.
Electrodesiccation with curettage – An older treatment that is particularly effective for small squamous cell carcinoma or basal cell carcinoma on the chest or back. In this procedure, a curette is used to scrape off cancerous tissue. Then the wound is closed with the superheating properties of electrodescication.
Topical medications – Effective topical treatments include 5-fluorouracil (5-FU), an at-home treatment that destroys superficial cancerous cells, and Imiquimod (IMQ), a new type of medication that triggers the immune system into destroying the malignant tissue. Picato™ can also be used for superficial skin cancer treatment as well as photodynamic therapy (see below).
Actinic Keratosis and Photodynamic Therapy
Actinic keratosis is a pre-cancerous skin lesion resulting from direct sun exposure. It commonly appears on the face, ears, back of the hands, and other sun-kissed areas of the body. It resembles an age spot but is scaly, reddish and feels rough to the touch. In fact, it is often felt before it is seen. It commonly starts out pink before darkening into a reddish-brown.
Actinic keratosis, left untreated, increases the risk of skin cancer. At Cosmetic Laser Dermatology, it is treated and removed with the innovative, non-invasive photodynamic therapy (PDT), in which a photo-sensitizing topical agent called ALA is applied to the targeted area. Multiple lights of a specific wavelength is then aimed at the targeted area to activate a photo-chemical reaction that destroys the cancerous lesion(s).
Mohs Surgery: Precision Cancer Treatment
One specialty of the West Dermatology & Skin Cancer Center is Mohs surgery. Several experienced, board-certified skin cancer surgeons under the direction of Shane Hamman, MD , including skin cancer expert Dr. Stacy D. Tompkins and dermapathologist Dr. Brook Brouha, are on staff to perform this procedure, which is backed by several decades of documented success in treating both squamous cell carcinoma, basal cell carcinoma and malignant melanoma. It has the highest cure rate of any skin cancer treatment and spares normal tissue.
Briefly, outpatient Mohs surgery skin cancer treatment is performed under local anesthetic as the dermatologist removes diseased tissue one layer at a time, which is immediately analyzed to determine whether or not more tissue must be removed. The process allows full removal of the malignant tissue in a single session—with very little damage to the surrounding healthy tissue.
