Cancer Stage Determines Risk Of Spreading And Line Of Treatment
A cancer of the upper layers of the skin in the epidermis, SCC is the second most common form of skin cancer after basal cell carcinoma and affects an estimated 1 million new people every year in the United States alone. Cancer staging is done for SCC with the intention of categorizing the size of cancer and to judge how much it has grown. And theres a clear line of treatment and way forward for each stage.1
With skin cancers like basal cell carcinoma, the likelihood of cancer spreading to other parts of the body is very low and early diagnosis and treatment usually tackles the problem before it spreads. SCC, however, is a little trickier. While the risk of spreading is still quite small, there is a relatively higher chance of it progressing depending on what stage the cancer is at. For those with weakened immune systems, say, people whove had organ transplants or anyone infected with HIV, the risk is a little higher. Also, when the cancer is in the head and neck region, it may have a slightly higher risk of recurring or spreading.2
The actual stage of this form of cancer is determined based on the TNM protocol devised by the American Joint Commission on Cancer.3
- T : The size/extent of the tumor
- N : Whether it has spread to lymph nodes
- M : Whether it has spread to other parts of the body

What Stages Have To Do With Cancer Spread
Cancers are staged according to tumor size and how far it has spread at the time of diagnosis. Stages help doctors decide which treatments are most likely to work and give a general outlook.
There are different types of staging systems and some are specific to certain types of cancer. The following are the basic stages of cancer:
- In situ. Precancerous cells have been found, but they havent spread to surrounding tissue.
- Localized. Cancerous cells havent spread beyond where they started.
- Regional. Cancer has spread to nearby lymph nodes, tissues, or organs.
- Distant. Cancer has reached distant organs or tissues.
- Unknown. Theres not enough information to determine the stage.
- Stage 0 or CIS. Abnormal cells have been found but have not spread into surrounding tissue. This is also called precancer.
- Stages 1, 2, and 3. The diagnosis of cancer is confirmed. The numbers represent how large the primary tumor has grown and how far the cancer has spread.
- Stage 4. Cancer has metastasized to distant parts of the body.
Your pathology report may use the TNM staging system, which provides more detailed information as follows:
T: Size of primary tumor
- TX: primary tumor cant be measured
- T0: primary tumor cant be located
- T1, T2, T3, T4: describes the size of the primary tumor and how far it may have grown into surrounding tissue
N: Number of regional lymph nodes affected by cancer
M: Whether cancer has metastasized or not

Melanoma Is The Fastest Growing Cancer
We are in the midst of a skin cancer epidemic with no end in sight. While most skin cancers are not life threatening, they can necessitate extensive surgery and cause deformities that need surgical correction. Luckily, the North State enjoys a crack collection of dermatologists and surgeons skilled in these arts. However melanoma is a different story. While almost 100% curable if caught early, melanoma has a dismal survival rate once it spreads beyond the skin. There is no know cure.
In conclusion, I would encourage each of you to see a dermatologist for a full skin exam. You may say to yourself, My moles look fine. Nothing has changed. To which I would ask, Would you bet your life on it?

Melanoma usually curable if found and treated early. Image courtesy of anthony m rossi, md, faad. Skin cancer is one of the most common types of cancer. Melanoma skin cancer has a rapid growth rate, which is what makes it so dangerous Scc is generally faster growing than basal cell cancers.
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.

How Is Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.
Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.
Basal Cell And Squamous Cell Survival Rates
Because basal cell and squamous cell carcinomas are lower-risk skin cancers, theres little information on survival rates based on stage.
Both types of cancer have a very high cure rate. According to the Canadian Cancer Society, the five-year survival rate for basal cell carcinoma is 100 percent. The five-year survival rate for squamous cell carcinoma is 95 percent.

Basal Cell Carcinoma Signs And Symptoms
This type of cancer is usually found on sun-exposed areas of the skin like the scalp, forehead, face, nose, neck and back.
Basal cell carcinomas may bleed after a minor injury but then scab and heal. This can happen over and over for months or years with no visible growth, making it easy to mistake them for wounds or sores. They rarely cause pain in their earliest stages.
Appearance
In addition to the bleeding and healing, these are other possible signs of a basal cell cancer:
- A persistent open sore that does not heal and bleeds, crusts or oozes.
- A reddish patch or irritated area that may crust or itch.
- A shiny bump or nodule that is pearly or translucent and often pink, red or white. It can also be tan, black or brown, especially in dark-haired people, and easy to confuse with a mole.
- A pink growth with a slightly elevated, rolled border and a crusted indentation in the center. Tiny blood vessels may appear on the surface as the growth enlarges.
- A scar-like lesion in an area that you have not injured. It may be white, yellow or waxy, often with poorly defined borders. The skin seems shiny and tight sometimes this can be a sign of an aggressive tumor.
After Squamous Cell Cancer Of The Skin Has Been Diagnosed Tests Are Done To Find Out If Cancer Cells Have Spread Within The Skin Or To Other Parts Of The Body
The process used to find out if cancer has spread within the skin or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment for squamous cell carcinoma of the skin.
Basal cell carcinoma of the skin rarely spreads to other parts of the body. Staging tests to check whether basal cell carcinoma of the skin has spread are usually not needed.
The following tests and procedures may be used in the staging process for squamous cell carcinoma of the skin:

What Are The Signs Of Skin Cancer
The most common warning sign of skin cancer is a change on your skin, typically a new growth, or a change in an existing growth or mole. The signs and symptoms of common and less common types of skin cancers are described below.
Basal cell carcinoma
Basal cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. Basal cell cancer is the most common type of skin cancer in the world. In most people, its slow growing, usually doesnt spread to other parts of the body and is not life-threatening.
Signs and symptoms of basal cell carcinoma include:
- A small, smooth, pearly or waxy bump on the face, ears, and neck.
- A flat, pink/red- or brown-colored lesion on the trunk or arms and legs.
- Areas on the skin that look like scars.
- Sores that look crusty, have a depression in the middle or bleed often.
Squamous cell carcinoma
Squamous cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. This skin cancer can also form in areas such as mucus membranes and genitals.
Signs and symptoms of squamous cell carcinoma include:
- A firm pink or red nodule.
- A rough, scaly lesion that might itch, bleed and become crusty.
Melanoma
Signs and symptoms of melanoma include:
- A brown-pigmented patch or bump.
- A mole that changes in color, size or that bleeds.
What Happens If Merkel Cell Carcinoma Is Left Untreated
Merkel cell carcinoma is a rare but aggressive and potentially fatal form of skin cancer. It typically affects people above the age of 50 and those who have weakened immune systems. In most cases, Merkel cell carcinoma begins as a skin-toned growth that may bleed easily. The bumps or nodules may also have blue, purple, or red coloring. Because the Merkle cells are near nerve endings, this form of cancer has numerous health risks, and if left untreated, Merkle cell cancer may spread to the brain, lungs, or bones, becoming fatal.

Who Gets Skin Cancer
Skin cancer tends to affect people of light skin color because they’re born with the least amount of protective melanin in their skin. The odds are highest if you’re:
- Redheaded
- A blue-eyed blonde
- Someone with a pigment disorder, such as albinism
People with many freckles or moles, particularly odd-looking ones, may be vulnerable to melanoma. It’s possible for dark-skinned people to get skin cancer, but it’s rare and usually on lighter areas of their body, such as the soles of the feet or under fingernails or toenails.
Where you live also plays a role. Places with intense sunshine, such as Arizona and Hawaii, have a larger share of people with skin cancer. It’s more common in places where fair-skinned people moved from less sunny areas, like Australia, which was settled largely by fair-skinned people of Irish and English descent.
About 3 times more men than women get skin cancer. It’s more likely when you’re older. Most people diagnosed are between ages 45 and 54, although more younger people are now being affected. If you or any close relatives have had skin cancer, your chances go up.
Where Do Skin Cancers Start
Most skin cancers start in the top layer of skin, called the epidermis. There are 3 main types of cells in this layer:
- Squamous cells: These are flat cells in the upper part of the epidermis, which are constantly shed as new ones form. When these cells grow out of control, they can develop into squamous cell skin cancer .
- Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skins surface. As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells. Skin cancers that start in the basal cell layer are called basal cell skin cancers or basal cell carcinomas.
- Melanocytes: These cells make the brown pigment called melanin, which gives the skin its tan or brown color. Melanin acts as the bodys natural sunscreen, protecting the deeper layers of the skin from some of the harmful effects of the sun. Melanoma skin cancer starts in these cells.
The epidermis is separated from the deeper layers of skin by the basement membrane. When a skin cancer becomes more advanced, it generally grows through this barrier and into the deeper layers.

Treatment Of Basal Cell Carcinoma
-
Removal of the tumor
Doctors may remove the cancer in the office by scraping and burning it with an electric needle or by cutting it out. Doctors may destroy the cancer by using extreme cold .
Certain chemotherapy drugs may be applied to the skin. Photodynamic therapy , in which chemicals and a laser are applied to the skin, also may be used. Occasionally, radiation therapy is used.
A technique called Mohs microscopically controlled surgery may be required for some basal cell carcinomas that are large or regrow or occur in certain areas, such as around the nose and eyes.
People whose cancer has spread to nearby tissues or spread to other parts of the body and who are not candidates for surgery or radiation therapy may be given the drug vismodegib or sonidegib taken by mouth.
