Skin Cancer Atlanta

Skin cancer is the most common form of human cancers, affecting more than one million Americans every year. One in five

Americans will develop skin cancer at some point in their lives. Skin cancers are generally curable if caught early. However, people who have had skin cancer are at a higher risk of developing a new skin cancer, which is why regular self-examination and doctor visits are imperative.

The vast majority of skin cancers are composed of three different types: Basal cell carcinoma, Squamous cell carcinoma and Melanoma.

Below is a summary of the various types of skin cancer. You can also find valuable information at http://www.skincancer.org/

Basal Cell Carcinoma

This is the most common form of skin cancer. Basal cells reside in the deepest layer of the epidermis, along with hair follicles and sweat ducts. When a person is overexposed to UVB radiation, it damages the body's natural repair system, which causes basal cell carcinomas to grow. These tend to be slow-growing tumors and rarely metastasize (spread). Basal cell carcinomas can present in a number of different ways:

  • raised pink or pearly white bump with a pearly edge and small, visible blood vessels
  • pigmented bumps that look like moles with a pearly edge
  • a sore that continuously heals and re-opens
  • flat scaly scar with a waxy appearance and blurred edges

Despite the different appearances of the cancer, they all tend to bleed with little or no cause. Eighty-five percent of Basal cell carcinomas occur on the face and neck since these are areas that are most exposed to the sun.

Risk factors for basal cell carcinoma include having fair skin, sun exposure, age (most skin cancers occur after age 50), exposure to ultraviolet radiation (as in tanning beds) and therapeutic radiation given to treat an unrelated health issue.

Diagnosing Basal cell carcinoma requires a biopsy — either excisional, where the entire tumor is removed along with some of the surrounding tissue, or incisional, where only a part of the tumor is removed (used primarily for large lesions).

Treatments for Basal cell carcinoma include:

  • Mohs Micrographic Surgery — The preferred method for tumors that are high-risk or in cosmetically sensitive locations, Mohs Micrographic Surgery combines removal of cancerous tissue with microscopic review while the surgery takes place. By mapping the diseased tissue layer by layer, less healthy skin is damaged when removing the tumor. At the same time, Mohs provides the highest cure rate of all methods, nearly 100% in most cases. Read More...
  • Curettage and Desiccation — This treatment involves using a small metal instrument called a curette to scrape out the tumor, along with the application of electric cautery to kill off any remaining cancer cells. It is used for low-risk, non-aggressive types of skin cancer. The cure rate is not as high as surgery or radiation.
  • Surgical Excision — With this  treatment  the tumor is surgically excised with appropriate margins onf normal skin, depending on the aggressiveness of the tumor. The specimen is sent to pathology to ensure the tumor has been completely removed.
  • Radiation Therapy — Radiation therapy is  a nonsurgical treatment that offers good cure rates. It requires multiple visits to a radiation oncologist over the period of a couple weeks. Radiation is used as second-line when surgery is not a good option. 

Squamous Cell Carcinoma

Squamous cells are found in the upper layer (the surface) of the epidermis. They look like fish scales under a microscope and present as a crusted or scaly patch of skin with an inflamed, red base. They are often tender to the touch. It is estimated that 250,000 new cases of squamous cell carcinoma are diagnosed annually, and that 2,500 of them result in death.

Squamous cell carcinoma can develop anywhere, including inside the mouth and on the genitalia. It most frequently appears on the scalp, face, ears and back of hands. Squamous cell carcinoma tends to develop among fair-skinned, middle-aged and elderly people who have a history of sun exposure. In some cases, it evolves from actinic keratoses, dry scaly lesions that can be flesh-colored, reddish-brown or yellow black, and which appear on skin that is rough or leathery. Actinic keratoses spots are considered to be precancerous.

Like Basal cell carcinoma, Squamous cell carcinoma is diagnosed via a biopsy

Treatments for Squamous cell carcinoma include:

  • Mohs Micrographic Surgery — The preferred method for tumors that are high-risk or in cosmetically sensitive locations, Mohs Micrographic Surgery combines removal of cancerous tissue with microscopic review while the surgery takes place. By mapping the diseased tissue layer by layer, less healthy skin is damaged when removing the tumor. At the same time, Mohs provides the highest cure rate of all methods, nearly 100% in most cases. Read More...

  • Radiation Therapy — Radiation therapy is  a nonsurgical treatment that offers good cure rates. It requires multiple visits to a radiation oncologist over the period of a couple weeks. Radiation is used as second-line when surgery is not a good option.

Melanoma

While Melanoma is the least common type of skin cancer, it is by far the most virulent. It is the most common form of cancer among young adults age 25 to 29. Melanocytes are cells found in the bottom layer of the epidermis. These cells produce melanin, the substance responsible for skin pigmentation. That is why Melanomas often present as dark brown or black spots on the skin. Melanomas spread rapidly to internal organs and the lymph system, making them quite dangerous. Early detection is critical for curing this skin cancer.

Melanomas look like moles and often do grow inside existing moles. That is why it is important for people to conduct regular self-examinations of their skin in order to detect any potential skin cancer early, when it is treatable. Most Melanomas are caused by overexposure to the sun beginning in childhood. This cancer also runs in families.

Melanoma is diagnosed via a biopsy. Melanoma is treated by wide surgical excision and close follow up care.

What to Look For

The key to detecting skin cancers is to notice changes in your skin. Look for:

  • Large brown spots with darker speckles located anywhere on the body.
  • Dark lesions on the palms of the hands and soles of the feet, fingertips toes, mouth, nose or genitalia.
  • Translucent pearly and dome-shaped growths.
  • Existing moles that begin to grow, itch or bleed.
  • Brown or black streaks under the nails.
  • A sore that repeatedly heals and re-opens.
  • Clusters of slow-growing scaly lesions that are pink or red.

The American Academy of Dermatology has developed the following ABCDE guide for assessing whether or not a mole or other lesion may be becoming cancerous.

Asymmetry: Half the mole does not match the other half in size, shape or color.

Border: The edges of the mole are irregular or blurred.

Color: The mole is not the same color throughout.

Diameter: The mole is larger than one-quarter inch in size.

Evolution: The mole changes in any way.

If any of these conditions occur, please make an appointment to see one of our dermatologists right away. The doctor may do a biopsy of the mole to determine if it is or isn't cancerous.

Prevention

Roughly 90% of nonmelanoma cancers are attributable to ultraviolet radiation from the sun. That is why prevention involves:

  • Staying out of the sun during peak hours (between 10 a.m. and 4 p.m.).
  • Covering up the arms and legs with protective clothing.
  • Wearing a wide-brimmed hat and sunglasses.
  • Using sunscreens year round with a SPF of 15 or greater and sunblocks that work on both UVA and UVB rays. Look for products that use the term "broad spectrum."
  • Checking your skin monthly and contacting your dermatologist if you notice any changes.
  • Getting regular skin examinations. It is advised that adults over 40 get an annual exam with a Dermatologist.
