Melanoma and Non-melanoma Skin Cancers

Skin cancer is the most common cancer in the United States, with an estimated 1 in 5 Americans diagnosed in their lifetime. It begins when cells in the outermost layer of the skin grow uncontrollably, often due to DNA damage from too much sun exposure. Over time, these damaged cells can develop into cancer.

At SCRI Oncology Partners in Nashville, our experienced skin cancer team specializes in the diagnosis and treatment of melanoma and non-melanoma skin cancers, including rare subtypes of melanoma. We provide patients with personalized skin cancer treatment plans, providing access to emerging therapies through clinical trials. Our team is here to help you through each step in your cancer journey.

What are the signs and symptoms of skin cancer?

Getting familiar with your skin and any changes you notice is one of the best ways to identify skin cancer at an early stage.

Non-melanoma skin cancers can appear in a few different ways.

  • Basal cell carcinoma may appear like an open sore, a red patch, a pink growth, a shiny bump, or a scar
  • Squamous cell carcinoma may present as a scaly red patch, an open sore, a wart, or an elevated growth with a central depression

These spots typically develop on areas of the skin that receive frequent sun exposure, such as the face, neck, ears, and hands.

Melanoma often appears as:

  • Changes in the size, shape, or color of existing moles
  • Refer to the acronym ABCDE
    • A -Asymmetry between sides,
    • B – Irregular border
    • C – Variation in color across the mole
    • D – Diameter >5mm
    • E – A lesion that is evolving or changing

The spots can appear anywhere on the body. It can appear in areas that don’t get sun exposure, such as the bottom of the feet or palms of your hands.

Regularly checking your skin can help you notice any unusual changes. If anything looks suspicious, it’s important to make an appointment with your healthcare provider or a dermatologist right away. The earlier skin cancer is identified and diagnosed, the easier it is to treat.

If you have a personal or family history of melanoma, a history of blistering sunburns, a history or current use of tanning beds, or have a large number of moles on your body, it’s advisable to see a dermatologist for an annual full-body skin cancer screening. Even if you don’t have any of these risk factors, scheduling annual screening appointments can help with the early detection of skin cancer.

During a skin cancer screening, the dermatologist will thoroughly examine your skin from head to toe. If any spots appear cancerous or precancerous, they will likely perform a biopsy for further evaluation.

How is skin cancer diagnosed?

Typically, skin cancer is diagnosed by a dermatologist or primary care provider (PCP) after removing a suspicious spot on the skin. Looking at the cells under a microscope allows a pathologist to see whether cancer cells are present. This is the only definitive method for diagnosing skin cancer.

Skin biopsies are usually performed in the provider’s office or as an outpatient procedure in a clinic or a hospital under local anesthesia.

In some cases, removing the spot for biopsy may be the only treatment needed. However, if cancer cells are confirmed, the provider may refer you to an oncologist for additional treatment.

Types of skin cancer

Skin cancer is categorized into two main types: non-melanoma and melanoma. Identifying the specific type is important, as it influences the recommended treatment approach.

Non-melanoma skin cancers

The two most common types of non-melanoma skin cancer are basal cell carcinoma and squamous cell carcinoma. When found early, most non-melanoma skin cancers require only surgery. However, radiation and medications are offered when the cancer appears to be growing aggressively, has spread to lymph nodes, or can’t be operated on.

Basal cell carcinoma
Basal cell carcinoma is the most common form of skin cancer that originates in the basal cells, which are found in the lower part of the epidermis, the outermost layer of the skin. This type of skin cancer typically develops on areas of the skin that are frequently exposed to the sun, such as the face, neck, and arms. However, it can also occur in less exposed areas. Unlike melanoma, basal cell carcinoma rarely spreads (metastasizes) to other parts of the body, but it can cause significant local damage if left untreated.
Squamous cell carcinoma
Squamous cell carcinoma is a common type of skin cancer that arises from the squamous cells, which make up the middle and outer layers of the skin. It’s most frequently found on sun-exposed areas of the body, such as the face, ears, neck, lips, and backs of the hands, but it can also develop in other areas, including the mouth, esophagus, and other internal organs. Unlike basal cell carcinoma, squamous cell carcinoma is more likely to spread (metastasize) to other parts of the body if not treated promptly.

Melanoma

Melanoma is a type of skin cancer that affects the cells in our skin that produce melanin, the pigment that gives our skin its color. While very rare, accounting for about 1% of all skin cancer diagnoses, it’s the most aggressive type.

Melanoma can develop in other areas of the body, such as the eye (referred to as uveal, choroidal, or conjunctival melanoma), and in mucous membranes, such as the gastrointestinal and genitourinary tracts or the sinuses (known as mucosal melanoma). Additionally, it can appear on the palms of the hands, soles of the feet, or fingers and toes, which is called acral melanoma.

The SCRI Oncology Partners team is experienced in caring for patients with these less common types of melanoma and can offer clinical trials when one is available for your type of cancer. If you need more information, please contact us.

Other rare skin cancers

Merkel cell carcinoma (MCC)
Merkel cell carcinoma is a rare, aggressive skin cancer that primarily occurs on skin that is more likely to be areas exposed to the sun, including the head, neck, arms, legs, and torso. MCC usually appears as a firm, pink, red, or purple lump on the skin. Typically, these lumps are painless. Because MCC is a fast-growing cancer, it can be hard to treat if it spreads to areas beyond the skin. If you notice anything irregular or abnormal, it is critical to connect with a skin cancer specialist.
Kaposi sarcoma
A type of cancer that develops from the cells that line lymph or blood vessels. It can appear on the skin as a darkish/purple-colored tumor (or lesion) or on the inside of the mouth.
Lymphoma of the skin
Lymphoma is a cancer that starts in the lymphocytes–white blood cells that are vitally important in the functioning of the immune system. While lymphoma commonly involves the lymph nodes, it can also begin in other lymphoid tissues, such as the spleen, bone marrow, and skin.

The two main types of lymphomas are Hodgkin lymphoma and non-Hodgkin lymphoma. Lymphomas that originate only in the skin are called cutaneous lymphoma (or lymphoma of the skin). In addition to some of the typical skin cancer treatments, such as photodynamic therapies, chemotherapy, and targeted therapies, cutaneous lymphoma may also be treated by stem cell transplants, immunotherapy treatments, and clinical trials.

Staging skin cancer

Cancer staging refers to the process of determining the extent of cancer in the body, including the size of the tumor and whether it has spread to other areas. Understanding the stage of cancer is crucial for doctors, as it helps them assess the severity of the disease, plan the most effective treatment, and identify suitable clinical trials that could serve as potential treatment options.

Non-melanoma staging

Stage 0

 

The abnormal cells are localized to the top layer of skin (carcinoma in situ).

 

Stage I

 

The tumor is 2 centimeters wide (three-quarters of an inch) or smaller.

 

Stage II

 

The tumor is larger than 2 centimeters wide.

 

Stage III

 

The tumor is >4cm wide, has spread along a nerve, or invades deep structures. Stage III also includes spread to nearby lymph nodes. It has not spread to other areas of the body.

 

Stage IV

 

The cancer has spread to lymph nodes with extranodal extension, regional lymph nodes, or metastasized to other parts of the body.

 

Melanoma staging

Stage 0

 

Melanoma cells are found only in the outer layer of skin cells and have not invaded deeper tissues.

     

    Stage I

     

    Melanoma in stage I is thin:

    • The tumor is no more than 1 millimeter (1/25 inch) thick. The outer layer (epidermis) of skin may appear scraped (ulceration).
    • Or, the tumor is between 1 and 2 millimeters (1/12 inch) thick. There is no ulceration. The melanoma cells have not spread to nearby lymph nodes.

     

    Stage II

     

    The tumor is at least 1 millimeter thick:

    • The tumor is between 1 and 2 millimeters thick. There is ulceration.
    • Or, the thickness of the tumor is more than 2 millimeters. There may be ulceration. The melanoma cells have not spread to nearby lymph nodes.

     

    Stage III

     

    Melanoma cells have spread to nearby tissues:

    • The melanoma cells have spread to one or more nearby lymph nodes.
    • Or, the melanoma cells have spread to tissues just outside the original tumor but not to any lymph nodes.

     

    Stage IV

     

    Melanoma cells have spread to other organs, lymph nodes, or distant skin areas from the original tumor.

     

    How is skin cancer treated?

    The treatment for skin cancer varies depending on its stage and type. 

    Localized Therapies

    Surgery

    Surgery is often the primary treatment for both non-melanoma skin cancers and melanoma. Various surgical techniques may be used, including wide local excision (WLE), Mohs surgery, and electrodesiccation and curettage. After surgery, a skin graft may be necessary to close the wound. Most surgical procedures can be performed in the doctor’s office. If surgery is not possible due to the lesion’s location, other treatments will be used to destroy the cancer cells.

    Radiation Therapy

    Radiation therapy may be recommended for skin cancer, especially in areas where surgery could be complicated or could leave significant scarring, such as on the eyelids, ears, top of the head, or nose. It can also be used post-surgery to eliminate any remaining cancer cells.

    Topical Chemotherapy

    For non-melanoma skin cancers, topical chemotherapy is often applied directly to the skin as a cream or lotion.

    Systemic Treatments for Skin Cancer

    Immunotherapy

    Immunotherapy is a common treatment approach for melanoma. These treatments include interferon and interleukin-2 (IL-2), which can slow tumor growth and boost the immune response by enhancing lymphocyte activity. Additionally, tumor necrosis factor (TNF) therapy, a protein produced by white blood cells, is often used alongside other melanoma treatments to kill cancer cells.

    Targeted Therapy

    Targeted therapy focuses on specific cancer cells with specific genetic changes. The choice of targeted therapies depends on the type of skin cancer. For melanoma, common targeted therapies include BRAF inhibitors, MEK inhibitors, and C-KIT inhibitors. In cases of basal cell carcinoma, treatments known as Hedgehog pathway inhibitors may be used.

    Chemotherapy

    For melanoma, chemotherapy is administered through an IV to target cancer cells throughout the body. In some cases, chemotherapy may be delivered directly to the affected area, known as regional chemotherapy.

    SCRI Oncology Partners offers these treatments, and new therapies being studied in clinical trials at our cancer center in Nashville.
