Squamous Cell Cancerthe Insidious Cutaneous Carcinoma
Your clinical day begins with Mr. Frederick Michael. Fred has a slow-growing crusty lesion on his cheek under his right eye. He states it has been growing for a few months and hurts when he gently presses it. The lesion has not bled. It is a 9 mm irregular patch with yellow scale. On close examination, you see a pink border. When you press it, he complains of discomfort. Fred states that he has had some strange twitching in the area of the lesion. He does not associate it with the spot. The skin of your patient is a Fitzpatrick two and he has fair eyes. You know his eye color is associated with pheomelanin, and he has had extensive sun exposure with a history of multiple sunburns.
You take an extensive history and find that he has an immune suppressant for a kidney transplant. He is 85 years old and is a heavy smoker, and he drinks alcohol times 4 per night. You decide to perform a shave biopsy of the lesion and find squamous cell cancer. Due to his age , immune suppression and other risk factors including alcohol and smoking thus, you decide to refer the patient for Mohs surgery. You also let Fred know that twitching can be due to a squamous cell cancer of the skin.
The MOHS surgeon calls back and lets you know that the lesion was removed with one stage and was a Castle one. The provider tells you that you had wisely managed this patient. Another good day at workright?

Do You Need Chemotherapy For Squamous Cell Carcinoma
Because just about all squamous cell carcinoma is usually localized it is typically not treated with chemotherapy. Chemotherapy is used for widespread cancer cell eradication, not localized growths. Chemotherapy could be used for a very small percentage of these cases, typically if the cancer has spread.
About 95 percent of squamous cell carcinomas are detected early, and this makes them easy to treat. All treatment options are highly successful, but Mohs micrographic surgery is the most successful while taking the least amount of healthy skin.
Squamous Cell Carcinoma Causes
Exposure to ultraviolet rays, like the ones from the sun or a tanning bed, affects the cells in the middle and outer layers of your skin and can cause them to make too many cells and not die off as they should. This can lead to out-of-control growth of these cells, which can lead to squamous cell carcinoma.
Other things can contribute to this kind of overgrowth, too, like conditions that affect your immune system.

The Clinical Course Of Squamous Cell Carcinoma
Although most patients who develop SCCs have localized disease that can be cured, tumor recurrence, tumor spread to other parts of the body, and death occasionally occurs.
Larger tumors may cause disfigurement as they may penetrate into the underlying tissues causing nerve or muscle damage. SCCs that have spread into the underlying tissue have been resistant to previous therapy or have reoccurred are considered advanced SCCs.
Squamous Cell Lung Carcinoma Outlook
The outlook for non-small cell lung cancers, such as squamous cell carcinoma, is better than for small cell lung carcinomas. Its also better when its caught and treated early. In fact, it can even be cured if caught early enough.
The outlook for people with cancer is measured by 5-year survival rates. This indicates the percentage of people who have a specific type of cancer who are alive 5 years or more after getting a diagnosis.
The American Cancer Society uses data from the National Cancer Institute to track the average 5-year survival rates for non-small cell lung cancers. It does this based on if and how cancer has spread:
- Localized: This is non-small cell lung cancer that hasnt spread outside of the lung. The 5-year survival rate is 63 percent.
- Regional: This is non-small cell lung cancer that has spread to the lymph nodes and other nearby organs in the chest. The 5-year survival rate is 35 percent.
- Distant: This is when non-small cell lung cancer has spread to more distant organs of the body, such as the liver, brain, or bones. The 5-year survival rate is 7 percent.
Its important to remember that these percentages are only a guide based on averages. Everyone is different. The percentages show that the key to having the best outlook is early detection and treatment before cancer spreads.

Surgery For Basal And Squamous Cell Skin Cancers
Surgery is a common treatment for basal cell and squamous cell skin cancers. Different surgical techniques can be used. The options depend on the type of skin cancer, how large the cancer is, where it is on the body, and other factors. Most often the surgery can be done in a doctors office or hospital clinic using a local anesthetic . For skin cancers with a high risk of spreading, surgery sometimes will be followed by other treatments, such as radiation or chemotherapy.
Signs And Symptoms Of Squamous Cell Carcinoma
It is important to see your dermatologist whenever you notice a change in a mole or area of your skin. Squamous cell carcinoma symptoms include:
- A sore that won’t heal, or that heals and then regrows
- An elevated growth on the skin that feels rough
- A reddish, scaly patch that grows slowly
If you have a sore or scab for more than two months without healing, or a flat patch of scaly skin that won’t go away, make an appointment to see your dermatologist.

Squamous Cell Carcinoma Remedies
Just diagnosed with SCC. Have extensive swelling in neck and arm. Biopsy was done showing SCC but could not pinpoint the primary source of the cancer. Did PET scan which showed the source being in the sinuses and the femor of left leg. Was told that there is no cure, the only option is Radiation and Chemo treatments which can shrink the multiple tumors and if it works would only give me more time and this would have to be repeated as the tumors start growing again. Started the radiation treatments last week and they will continue for several weeks and then chemo for several weeks. They say the most I can even hope for is a max of 18 months. Is there anything that I can do? Please help, willing to try anything.
How Is Squamous Cell Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Squamous cell cancers are staged by size and extent of growth. Squamous cell cancers can metastasize to nearby lymph nodes or other organs, and can invade both small and large nerves and local structures.
Biopsy can help determine if the squamous cell cancer is a low-risk tumor or a high-risk tumor that requires more aggressive treatment. Low-risk tumors are less than 10 millimeters in size, less than or equal to 5 millimeters deep and do not involve structures beyond the surrounding fat. High-risk tumors in the head and neck are those that involve the central face, nose and eye area, as well as those tumors that are greater than or equal to 10 millimeters on the cheeks, scalp and neck, tumors that are more than 5 millimeters thick or involve adjacent structures, tumors that invade nerves, tumors that are recurrent or arising from previously radiated tissue, and tumors arising in patients who are immunosuppressed.

How To Treat Squamous Cell Carcinoma
Squamous cell carcinoma is not life-threatening, but it is important to not delay treatment following diagnosis, as Squamous cell carcinomas that have reached a more advanced stage can become more difficult to treat and may pose the risk of spreading. There are several options for how to treat Squamous cell carcinoma, including Mohs surgery and radiation delivered via Image Guided Superficial Radiotherapy . However, the methods available to each patient may vary depending on the location, size, and depth of the Squamous cell carcinoma, as well as the patients age and overall health condition.
GentleCure believes you should feel empowered and well-informed when making a treatment decision. In the guide below, we provide more details on available options so you can feel confident in your choice.
How Is Squamous Cell Skin Cancer Treated
Although squamous cell cancers usually grow slowly, it is important to see a dermatologist quickly. “The sooner you see your doctor and the cancer is diagnosed and treated, the less complicated the surgery to remove it will be, and the faster you will make a complete recovery, Dr. Leffell explains. The treatment for squamous cell cancer varies according to the size and location of the lesion. The surgical options are the same as those for basal cell cancer:
- Surgical excision: Removing a squamous cell lesion is a simple procedure that typically takes place in the dermatologist’s office. After numbing the cancer and the area around it with a local anesthetic, the doctor uses a scalpel to remove the tumor and some of the surrounding skin to make sure all cancer is eliminated. Estimating how much to take requires skill and expertise, Dr. Leffell notes. The risk of taking too little tissue is that some cancer remains taking too much leaves a larger scar than is necessary. Shaped like a football, the wound is stitched together, using plastic surgery techniques. If dissolvable stitches are used, they will disappear on their own as the area heals. Though the procedure leaves some redness and a small scar, it tends to become less noticeable over time. “The cure rate for this type of excision is typically about 90 to 93 percent,” says Dr. Leffell. But, of course, this is dependent on the skill and experience of the doctor.”

Scc Is Mainly Caused By Cumulative Uv Exposure Over The Course Of A Lifetime
If youve had a basal cell carcinoma you may be more likely to develop a squamous cell skin carcinoma, as is anyone with an inherited, highly UV-sensitive condition such as xeroderma pigmentosum.
Chronic infections, skin inflammation, HIV and other immune deficiency diseases, chemotherapy, anti-rejection drugs used in organ transplantation, and excessive sun exposure can all lead to a risk of squamous cell carcinoma.
Occasionally, squamous cell carcinomas arise spontaneously on what appears to be normal, healthy skin. Some researchers believe the tendency to develop these cancers can be inherited.
SCCs may occur on all areas of the body including the mucous membranes and genitals, but are most common in areas frequently exposed to the sun:
- Previous BCC or SCC
- Chronic inflammatory skin conditions or chronic infections
But anyone with a history of substantial sun exposure is at increased risk. Those whose occupations require long hours outside or who spend their leisure time in the sun are also at risk.
What Are The Symptoms Of Squamous Cell Skin Cancer
Squamous cell cancers are usually raised growths, ranging from the size of a pea to the size of a chestnut. They may appear as scaly red patches, open sores or protruding growths with a dented center, or they may look like a wart. Most are found in areas of the body that are frequently exposed to the sun, such as the ears, lips, face, balding scalp, neck, hands, arms, and legs. Less commonly, they may appear on mucous membranes and genitals. Regardless of what form the bumps take, they do not heal or go away on their own.

Treatments For Squamous Cell Carcinoma
The following are treatment options for squamous cell carcinoma of the skin. Your healthcare team will suggest treatments based on the . They will work with you to develop a treatment plan.
SCC is most often treated with local therapy. This means that only the cancer on the skin and the area around it are treated.
But if SCC has spread to other parts of the body, systemic therapy may be used. Systemic therapy travels through the bloodstream to reach and destroy cancer cells all over the body.
What Is Aggressive Squamous Cell Carcinoma
- Larger than 2 centimeters
- Deeper than 2 millimeters
- Near the lip and ear
- Located in a scar or other injured skin
- Spread into a nerve
- Poorly differentiated
Having a weakened immune system due to medications or infections increases the risk of aggressive SCC. History of radiation exposure or use of psoralen UVA treatment are other risk factors for aggressive SCC.9

Diagnosing Squamous Cell Carcinoma
The main way to diagnose squamous cell carcinoma is with a biopsy. This involves having a small piece of tissue removed from the suspicious area and examined in a laboratory.
In the laboratory, a pathologist will examine the tissue under a microscope to determine if it is a skin cancer. He or she will also stage the cancer by the number of abnormal cells, their thickness, and the depth of penetration into the skin. The higher the stage of the tumor, the greater the chance it could spread to other parts of the body.
Squamous cell carcinoma on sun-exposed areas of skin usually does not spread. However, squamous cell carcinoma of the lip, vulva, and penis are more likely to spread. Contact your doctor about any sore in these areas that does not go away after several weeks.
What Are The Treatments For Squamous Cell Carcinoma
Your doctor will help you to decide on the best type of treatment. Factors in the decision include your overall health and age, the location of the cancer, and how invasive the cancer is.
Treatment options include:
- Scratching off with a curette, an instrument that may end in a ring or a spoon, and then burning with a special electric needle. This method is called electrodessication and curettage.
- Surgical removal:
- Mohs surgery: This is a specialized technique. The doctor first removes the visible cancer and then begins cutting around the edges. The tissues are examined during the surgery until no more cancer cells are found in tissues around the wound. If necessary, a skin graft or flap might be applied to help the wound heal.
- Excisional surgery: The growth and a bit of surrounding skin is removed with a scalpel.
If you have some type of advanced or very invasive SCC, you might find that it returns or metastasizes . There are several medications which have been approved to treat locally advanced cancers that cannot be simply treated or those that have spread to other areas of the body.

Staging Of Squamous Cell Carcinoma
Staging of squamous cell carcinomas is used to determine if, or how far, the cancer has spread. Treatment plans are determined by the stage or extent of the disease.
Factors that determine the stage of an SCC include:
- the size of the tumor
- the depth of growth into the skin
- whether the tumor has spread to lymph nodes or other parts of the body
Cancer staging helps determine treatment plans and provides information about survival.
Squamous cell carcinoma staging is based on the American Joint Committee on Cancer TNM system.
T Primary Tumor: Determined by tumor size and thickness, high-risk features, and level of invasion.
N Regional Lymph Nodes: Based on the location and number of lymph nodes with cancer cells, and the size of the metastatic tumor.
M Metastasis: Whether the tumor has spread to other parts of the body.
Once the detailed TNM stage is obtained, a simpler five-level stage is determined. The lower the stage, the better the prognosis.
Thinking About Taking Part In A Clinical Trial
Clinical trials are carefully controlled research studies that are done to get a closer look at promising new treatments or procedures. Clinical trials are one way to get state-of-the art cancer treatment. In some cases they may be the only way to get access to newer treatments. They are also the best way for doctors to learn better methods to treat cancer. Still, they’re not right for everyone.
If you would like to learn more about clinical trials that might be right for you, start by asking your doctor if your clinic or hospital conducts clinical trials.

Treating Squamous Cell Carcinoma Of The Skin
Treatment options for squamous cell skin cancer depend on the risk of the cancer coming back, which is based on factors like the size and location of the tumor and how the cancer cells look under a microscope, as well as if a person has a weakened immune system.
Most squamous cell skin cancers are found and treated at an early stage, when they can be removed or destroyed with local treatment methods. Small squamous cell cancers can usually be cured with these treatments. Larger squamous cell cancers are harder to treat, and fast-growing cancers have a higher risk of coming back.
In rare cases, squamous cell cancers can spread to lymph nodes or distant parts of the body. If this happens, treatments such as radiation therapy, immunotherapy, and/or chemotherapy may be needed.
Staging For Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin Depends On Where The Cancer Formed
Staging for basal cell carcinoma and squamous cell carcinoma of the eyelid is different from staging for basal cell carcinoma and squamous cell carcinoma found on other areas of the head or neck. There is no staging system for basal cell carcinoma or squamous cell carcinoma that is not found on the head or neck.
Surgery to remove the primary tumor and abnormal lymph nodes is done so that tissue samples can be studied under a microscope. This is called pathologic staging and the findings are used for staging as described below. If staging is done before surgery to remove the tumor, it is called clinical staging. The clinical stage may be different from the pathologic stage.
