Skin Cancer Of The Head And Neck Treatment
Many early-stage small basal cell cancers or squamous cell cancers can be removed by Mohs surgery, a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Tumors with nerve involvement, lymph node involvement or of a large size are not suitable for Mohs surgery. They require a multimodality approach to treatment, with formal surgical resection and adjuvant radiation or chemotherapy.
Melanoma is more likely to spread, and aggressive surgical resection with wide margins is required, in addition to radiation and/or chemotherapy.
How Is Melanoma Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Melanoma is diagnosed by the presence of abnormal melanocytes.
Melanoma of the skin is staged based on how deeply it invades the skin layers and whether or not it has spread. A superficial or shave biopsy will not provide the accurate staging information used to guide treatment. The depth of invasion determines the risk of spread to lymph nodes or other organs. Ulceration and microsatellitosis are additional diagnostic features that, when present, are associated with a higher risk of spread. In patients without clinically enlarged lymph nodes, sentinel lymph node biopsy is used to determine if microscopic spread to lymph nodes in the neck has occurred, and is used for all but very thin melanomas unless other high-risk features are present.
This information is used for staging, to guide prognosis and further treatment. Thick melanomas are associated with a higher risk of spread to other organs, which is evaluated by pretreatment imaging. When enlarged lymph nodes are detected on clinical exam, a fine needle aspiration biopsy is performed to determine whether melanoma is present in nodes.
Some subtypes of melanoma may be less likely to spread: lentigo maligna and desmoplastic melanoma. The role of sentinel node biopsy is controversial in these cases, and will be discussed with you by your treatment team.
What Are The Most Common Types Of Skin Cancer
When it comes to skin cancer, you’ll often hear dermatologists talk about “the big three.”
“The three most common forms of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma,”Anne Marie McNeill, a board-certified dermatologist in California and a spokesperson for the Skin Cancer Foundation , tells Allure. Here’s a visual guide to each type, though you should always see your dermatologist ASAP if you notice any new patches or spots on your skin.
Basal Cell Carcinoma
superficial basal cell carcinoma
Basal cell carcinoma is the most common form of skin cancer, according to the Skin Cancer Foundation. It estimates 3.6 million cases are diagnosed in the U.S. each year. Though it’s fairly common, relatively few people die from basal cell carcinomas the SCF estimates the annual number of deaths is around 3,000.
“Basal cells can look lots of different ways,” says Dr. McNeill. Most commonly, they’ll look like little red patches or open sores. Sometimes, these spots have a raised border with an indentation in the center, according to the Skin Cancer Foundation. But they can also look more unassuming like a flat scar, a patch of eczema, or a pearly pimple. “I often tell my patients if they have a spot that looks like a pimple or a sore , I want them to come in,” Dr. McNeil says. “It’s probably not a pimple if it hasn’t gone away after a month.”

The Ugly Duckling Sign Of Melanoma
The “ugly duckling” sign is a method for spotting changes in the skin commonly seen with melanoma. The aim is to check for moles that look significantly different from other moles in terms of their color, shape, or texture. These “ugly ducklings” warrant further investigation by a skin specialist known as a dermatologist.
What Is Melanoma Of The Head And Neck
Melanoma is a cancer that arises from melanocytes, the cells that give skin its pigment or color. Melanoma most commonly occurs in skin cells, but can rarely also occur in mucous membranes of the respiratory, gastrointestinal, genital or urinary organs. Melanoma arising in skin cells is caused by ultraviolet radiation from exposure to the sun and tanning beds.
Melanoma is the least common form of skin cancer, but it is responsible for more deaths per year than all other skin cancers combined. Melanoma is also more likely than other skin cancers to spread, and may be harder to control. However, approximately 75% of melanomas are found before they have spread, and can be cured with treatment. Mucosal melanomas make up 1% of all melanomas, and are more likely to spread to other sites

Diagnosis Of Scalp Cancer
To diagnose skin cancer on your scalp, your health care provider may:
- Examine the skin on your scalp to find out whether the changes in your skin are likely due to cancer
- Perform a skin biopsy where they remove a small sample of the suspicious skin and send it to a lab for testing
If you have scalp cancer, your health care provider may recommend additional testing to determine the stage of skin cancer, especially for melanoma and squamous cell cancer. Additional tests may include imaging studies to examine nearby lymph nodes for any signs of carcinoma or a biopsy of a lymph node .
What Are The Causes And Risk Factors For Skin Cancer On The Scalp
The main cause of skin cancer is UV radiation. This can occur from exposure to the sun or tanning beds.
Other risk factors include:
- prior radiation therapy to the head
- lighter skin color, although skin cancer on the scalp can occur with any skin color
- a history of multiple sunburns or excessive UV exposure

Who Is Most At Risk For Skin Cancer
Although anyone can develop skin cancer, youre at increased risk if you:
- Spend a considerable amount of time working or playing in the sun.
- Get easily sunburned have a history of sunburns.
- Live in a sunny or high-altitude climate.
- Tan or use tanning beds.
- Have light-colored eyes, blond or red hair and fair or freckled skin.
- Have many moles or irregular-shaped moles.
- Have actinic keratosis .
- Have a family history of skin cancer.
- Have had an organ transplant.
- Take medications that suppress or weaken your immune system.
- Have been exposed to ultraviolet light therapy for treating skin conditions such as eczema or psoriasis.

Where Does Bcc Develop
As the above pictures show, this skin cancer tends to develop on skin that has had lots of sun exposure, such as the face or ears. Its also common on the bald scalp and hands. Other common areas for BCC include, the shoulders, back, arms, and legs.
While rare, BCC can also form on parts of the body that get little or no sun exposure, such as the genitals.
What Is Squamous Cell Skin Cancer Of The Head And Neck
Skin malignancies are the most common cancer in the United States, responsible for more than half of all new cancer cases. These can be broken down into melanoma and non-melanoma malignancies, which are squamous cell cancer and basal cell cancer. These skin malignancies are caused by ultraviolet radiation from exposure to the sun and tanning beds.
Squamous cell cancer is the second most common form of skin cancer. It is more aggressive and may require extensive surgery depending on location and nerve involvement. Radiation, chemotherapy and immunotherapy are used in advanced cases.

How Is Skin Cancer Treated
Treatment depends upon the stage of cancer. Stages of skin cancer range from stage 0 to stage IV. The higher the number, the more cancer has spread.
Sometimes a biopsy alone can remove all the cancer tissue if the cancer is small and limited to your skins surface only. Other common skin cancer treatments, used alone or in combination, include:
Cryotherapy uses liquid nitrogen to freeze skin cancer. The dead cells slough off after treatment. Precancerous skin lesions, called actinic keratosis, and other small, early cancers limited to the skins top layer can be treated with this method.
Excisional surgery
This surgery involves removing the tumor and some surrounding healthy skin to be sure all cancer has been removed.
Mohs surgery
With this procedure, the visible, raised area of the tumor is removed first. Then your surgeon uses a scalpel to remove a thin layer of skin cancer cells. The layer is examined under a microscope immediately after removal. Additional layers of tissue continue to be removed, one layer at a time, until no more cancer cells are seen under the microscope.
Mohs surgery removes only diseased tissue, saving as much surrounding normal tissue as possible. Its most often used to treat basal cell and squamous cell cancers and near sensitive or cosmetically important areas, such as eyelids, ears, lips, forehead, scalp, fingers or genital area.
Curettage and electrodesiccation
Chemotherapy and immunotherapy
What Are The Symptoms Of Basal Cell Cancer Of The Head And Neck
Basal cell cancers usually present as an abnormal growth on the skin. The growth may have the appearance of a wart, crusty spot, reddish patch, mole, nodule or bump, or a sore that does not heal. It may or may not bleed and can sometimes be painful. These are usually slow-growing tumors that begin as small spots on sun-exposed areas of the face. Because they can have such a range of appearances, any new persistent skin lesion should be evaluated.

Who Gets Skin Cancer And Why
Sun exposure is the biggest cause of skin cancer. But it doesn’t explain skin cancers that develop on skin not ordinarily exposed to sunlight. Exposure to environmental hazards, radiation treatment, and even heredity may play a role. Although anyone can get skin cancer, the risk is greatest for people who have:
- Fair skin or light-colored eyes
- An abundance of large and irregularly-shaped moles
- A family history of skin cancer
- A history of excessive sun exposure or blistering sunburns
- Lived at high altitudes or with year-round sunshine
- Received radiation treatments
What Is Scalp Melanoma
Melanoma is a serious and potentially deadly form of skin cancer. It is more likely to spread locally as well as metastasize , and it accounts for more skin cancer-related deaths than basal and squamous cell carcinomas combined. Melanoma takes its name from melanocytes, the skins pigment-producing cells, where this condition originates. All types of melanoma are more likely to spread to lymph nodes and other tissues, but on the scalp, there are numerous blood vessels and other tissues that can quickly be impacted by melanoma cells.
According to Dr. Walker, The good news is that scalp melanoma is one of the rarest forms of this cancer, accounting for less than 5% of melanoma cases. The bad news is that scalp melanoma tends to be a more severe prognosis than other forms of melanoma. However, research indicates that this is largely because of how late in development its typically diagnosed. Simply put, people are more likely to overlook this condition until its very advanced, making it more difficult to treat.

What Are The Symptoms Of Skin Cancer Of The Head And Neck
Skin cancers usually present as an abnormal growth on the skin. The growth may have the appearance of a wart, crusty spot, ulcer, mole or sore. It may or may not bleed and can be painful. If you have a preexisting mole, any change in the characteristics of this spot – such as a raised or an irregular border, irregular shape, change in color, increase in size, itching or bleeding – are warning signs of melanoma. Sometimes the first sign of melanoma or squamous cell cancer is an enlarged lymph node.
Basal Cell And Squamous Cell Carcinomasigns And Symptoms
The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore that doesn’t heal. The cancer may start as a small, smooth, shiny, pale or waxy lump. It also may appear as a firm red lump. Sometimes, the lump bleeds or develops a crust.
Both basal and squamous cell cancers are found mainly on areas of the skin that are exposed to the sun the head, face, neck, hands and arms. But skin cancer can occur anywhere.
An early warning sign of skin cancer is the development of an actinic keratosis, a precancerous skin lesion caused by chronic sun exposure. These lesions are typically pink or red in color and rough or scaly to the touch. They occur on sun-exposed areas of the skin such as the face, scalp, ears, backs of hands or forearms.
Actinic keratoses may start as small, red, flat spots but grow larger and become scaly or thick, if untreated. Sometimes they’re easier to feel than to see. There may be multiple lesions next to each other.
Early treatment of actinic keratoses may prevent them from developing into cancer. These precancerous lesions affect more than 10 million Americans. People with one actinic keratosis usually develop more. Up to 1 percent of these lesions can develop into a squamous cell cancer.
Basal cell carcinoma is the most commonly diagnosed skin cancer. In recent years, there has been an upturn in the diagnoses among young women and the rise is blamed on sunbathing and tanning salons.

What Is Skin Cancer
Skin cancer happens when skin cells grow and multiply in an uncontrolled, unorderly way.
Normally, new skin cells form when cells grow old and die or when they become damaged. When this process doesnt work as it should, a rapid growth of cells results. This collection of cells may be noncancerous , which dont spread or cause harm, or cancerous, which may spread to nearby tissue or other areas in your body if not caught early and treated.
Skin cancer is often caused by ultraviolet light exposure from the sun.
There are three main types of skin cancer:
Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer and are sometimes called non-melanoma skin cancer.
Melanoma is not as common as basal cell or squamous cell carcinomas but is the most dangerous form of skin cancer. If left untreated or caught in a late-stage, melanomas are more likely to spread to organs beyond the skin, making them difficult to treat and potentially life-limiting.
Fortunately, if skin cancer is identified and treated early, most are cured. This is why it is important to take a few safeguards and to talk with your healthcare provider if you think you have any signs of skin cancer.
Disparities In Mortality Risk
People of Color have a lower likelihood of developing skin cancers but are more likely to die from them compared with white people. According to a 2017 article, Hispanic, American Indian, and Black people in the U.S. have a two- to threefold higher risk of mortality from malignant melanoma compared with white people.
There is a higher incidence of malignant melanoma appearing under nail beds and on areas of skin not exposed to the sun among People of Color.
People of Color also have a disproportionately
Generally, healthcare professionals such as dermatologists diagnose skin cancer on the scalp through a physical exam and a biopsy. They may recommend additional tests to determine the cancer stage.
There are of skin biopsy:
- a shave biopsy, which involves shaving off the growth
- a punch biopsy, which involves using a special tool to remove a circular sample from the growth
- an incisional biopsy, which involves using a scalpel to remove a portion of the growth
- an excisional biopsy, which involves using a scalpel to remove all of the growth
Sometimes, such as in the case of melanoma, a regular biopsy may not be enough to determine the stage of cancer. In such cases, healthcare professionals may conduct a
