From The Harvard Health Letter May 2006
Summers the season for fun in the sunbut also for skin cancer. Of the three main types of skin cancer, melanoma is most deadly, and basal cell, most common. Squamous cell cancer falls in between. Its three times as common as melanoma . Though not as common as basal cell , squamous cell is more serious because it is likely to spread . Treated early, the cure rate is over 90%, but metastases occur in 1%5% of cases. After it has metastasized, its very difficult to treat.
Basal Cell Nevus Syndrome
In this rare congenital condition, people develop many basal cell cancers over their lifetime. People with this syndrome may also have abnormalities of the jaw , eyes, and nervous tissue.
Most of the time this condition is inherited from a parent. In families with this syndrome, those affected often start to develop basal cell cancers as children or teens. Exposure to UV rays can increase the number of tumors these people get.
What Does Most Dangerous Skin Cancer Look Like
Skin cancer typically stands out as being different to surrounding skin. If a spot strikes you as being a bit odd, take it seriously it is worth getting it had a look at.
Skin cancer mainly looks like a new and uncommon looking spot. It may likewise look like an existing spot that has actually altered in color, size or shape.
Here are some different types of skin cancers :

Treating Advanced Squamous Cell Cancers
Lymph node dissection:Removing regional lymph nodes might be recommended for some squamous cell cancers that are very large or have grown deeply into the skin, as well as if the lymph nodes feel enlarged and/or hard. The removed lymph nodes are looked at under a microscope to see if they contain cancer cells. Sometimes, radiation therapy might be recommended after surgery.
Immunotherapy: For advanced squamous cell cancers that cant be cured with surgery or radiation therapy, one option might be using an immunotherapy drug such as cemiplimab or pembrolizumab . However, these drugs havent been studied in people with weakened immune systems, such as people who take medicines for autoimmune diseases or who have had an organ transplant, so the balance between benefits and risks for these people isnt clear.
Systemic chemotherapy and/or targeted therapy:Chemotherapy and targeted therapy drugs might be other options for patients with squamous cell cancer that has spread to lymph nodes or distant organs. These types of treatment might be combined or used separately.

What Is Skin Cancer
Cancer can start any place in the body. Skin cancer starts when cells in the skin grow out of control.
Skin cancer cells can sometimes spread to other parts of the body, but this is not common. When cancer cells do this, its called metastasis. To doctors, the cancer cells in the new place look just like the ones from the skin.
Cancer is always named based on the place where it starts. So if skin cancer spreads to another part of the body, its still called skin cancer.

Symptoms Of Squamous Cell Carcinoma Of The Skin
Its important to get anything that looks suspicious checked out. Left untreated, squamous cell carcinomas can invade further into the skin and spread to other parts of the body.
They can grow extremely quickly and be very dangerous, said Dr. Amy McMichael, chair of the dermatology department at Wake Forest Baptist Health in North Carolina and a member of the American Academy of Dermatology. Sometimes if we wait a month, they are too big to remove in the office and you have to go to the operating room.

Understanding Non Melanoma Skin Cancers
The prognosis for cutaneous squamous cell carcinoma is usually good, but some patients have poor outcomes. To identify factors associated with poor outcomes, researchers conducted a 10-year retrospective cohort study that included 985 patients and 1,832 tumors. The majority of patients had one tumor, 21.2 percent of patients had two to four tumors, and a small percentage of patients had more than four tumors. Most were treated with standard excision and 20.2 percent were treated with Mohs surgery.
The data revealed that 4.6 percent of patients experienced local recurrence, 3.7 percent developed metastases, and 2.1 percent died from the disease. Upon analysis, one consistent predictor of poor outcome was tumor size of 2 cm or more. Multivariate risk analysis revealed that several specific disease factors were associated with metastasis and disease-specific death:
Get To Know Your Skin And Check It Regularly
Look out for changes such as:
- A mole that changes shape, color, size, bleeds, or develops an irregular border
- A new spot on the skin that changes in size, shape, or color
- Sores that don’t heal
- New bumps, lumps, or spots that don’t go away
- Shiny, waxy, or scar type lesions
- New dark patches of skin that have appeared
- Rough, red, scaly, skin patches
If you notice any changes to your skin, seek advice from a medical professional. Basal cell carcinoma is very treatable when caught early.

Is Squamous Cell Carcinoma Deadly
Skin cancer is by far the most common type of cancer and each year there are more new cases of skin cancer than the combined cases of breast, prostate, lung and colon cancer. This translates to one in five Americans developing skin cancer over their lifetime. Following basal cell carcinoma, squamous cell carcinoma is the second most common type of skin cancer. According to the American Cancer Society, about 5.4 million basal and squamous cell skin cancers are diagnosed each year in America. Squamous cell carcinoma accounts for ~20% of these cases.
Who is at risk for squamous cell carcinoma?Skin cancer occurs at every age in persons of every ethnicity and gender. Risk for squamous cell carcinoma increases with the following factors:
- Ultraviolet light exposure from the sun and indoor tanning
- History of sunburns, especially during childhood
- Lighter skin color equating to increased sensitivity to ultraviolet light. Although less common overall in darker skin types, squamous cell carcinoma accounts for a larger proportion of skin cancers in this population.
- Incidence increases with age
- Male gender men are especially at risk after age 60, whereas women account for more skin cancers in those under age 40
- Personal or family history of skin cancer
- Human Papillomavirus Virus infection
- Within scars from burns or other injuries as well as non-healing wounds of any type
Squamous Cell Carcinoma Treatment
Squamous cell carcinomas detected at an early stage and removed promptly are almost always curable and cause minimal damage. However, left untreated, they may grow to the point of being very difficult to treat.
A small percentage may even metastasize to distant tissues and organs. Your doctor can help you determine if a particular SCC is at increased risk for metastasis and may need treatment beyond simple excision.
Fortunately, there are several effective ways to treat squamous cell carcinoma. The choice of treatment is based on the type, size, location, and depth of penetration of the tumor, as well as the patients age and general health. Squamous cell carcinoma treatment can almost always be performed on an outpatient basis.

Hematopoietic Stem Cell Transplantation
Patients after hematopoietic stem cell transplantation are at a higher risk for oral squamous cell carcinoma. Post-HSCT oral cancer may have more aggressive behavior with poorer prognosis, when compared to oral cancer in non-HSCT patients. This effect is supposed to be owing to the continuous lifelong immune suppression and chronic oral graft-versus-host disease.
What Are The Symptoms Of Squamous Cell Skin Cancer Of The Head And Neck
Squamous cell skin cancers usually present as an abnormal growth on the skin or lip. The growth may have the appearance of a wart, crusty spot, ulcer, mole or a sore that does not heal. It may or may not bleed and can be painful. If you have a preexisting mole, any changes in the characteristics of this spot such as a raised or irregular border, irregular shape, change in color, increase in size, itching or bleeding are warning signs. Pain and nerve weakness are concerning for cancer that has spread. Sometimes a lump in the neck can be the only presenting sign of skin cancer that has spread to lymph nodes, particularly when there is a history of previous skin lesion removal.

Squamous cell carcinoma develops when the flat cells in the toplayer of skin grow and divide in an uncontrolled way.
You can get an SCC wherever there are squamous cells which is in manydifferent parts of the body. However, typically they appear on parts of theskin that have been exposed to a lot of ultraviolet radiation from the sunor from tanning beds.
An early form of skin cancer, called Bowen’s disease, which looks like a red, scaly patch, can also develop into an SCC if nottreated.
An SCC can be quite an aggressive cancer if left untreated. If you evernotice a sore, scab or scaly patch of skin that doesnt heal within 2 months,see a doctor.

How Is Squamous Cell Carcinoma Of The Skin Treated When It Spreads
When this cancer spreads beyond the skin, it travels to the lymph nodes or other organs. Once it spreads, a patient has advanced cancer.
If youâve been diagnosed with advanced SCC, you will be cared for by a team of medical professionals. This team will include oncologists . Your treatment plan may include one or more of the following:
Surgery: When surgery can remove the cancer and youre healthy enough to have surgery, this is often the preferred treatment. After surgery, another treatment, such as radiation therapy or chemotherapy, is often given. Adding another treatment helps to kill cancer cells.
Radiation therapy: Radiation can target cancer cells in the skin, lymph nodes, or other areas of the body. When a patient has advanced SCC, radiation therapy is often used along with another treatment.
Immunotherapy: This type of treatment helps strengthen your immune system so that it can fight the cancer. Drugs called immunotherapy medications are given for this purpose.
The U.S. Food and Drug Administration has approved one immunotherapy medication for the treatment of advanced SCC of the skin. Its called cemiplimab-rwlc.
In the clinical trials that led the FDA to approve cemiplimab-rwlc, about half the patients who had advanced SCC of the skin had their tumors shrink. In many patients who had tumor shrinkage, the shrinking lasted 6 months or longer. A few patients had their tumors disappear completely.
Pembrolizumab is also given by IV infusion.
Staging Basal Cell Carcinoma
In most cases, basal cell carcinoma does not require staging because it rarely spreads. Staging is only applicable if your cancer is very large or has spread. It determines how severe the cancer is and how to treat it.
The TNM system is used most often to stage cancer:
- Tumor: Takes into consideration tumor size and if it has infiltrated into other structures nearby, such as bone.
- Node: Describes cancer spread to the lymph nodes.
- Metastases: Identifies if cancer has spread to other distant body parts.

- A red sore or rough patch inside your mouth
- A red, raised patch or wart-like sore on or in the anus or on your genitals
What Are The Risk Factors For Squamous Cell Carcinoma
UV light exposure from the sun or indoor tanning equipment is the primary risk factor for skin cancer. People who live in areas with intense year-round sunshine tend to have a higher exposure and risk of skin cancer. Other squamous cell carcinoma risk factors include:
- Fair skin, light eyes, and naturally light-colored hair
- History of or blistering sunburns when you were young
- Presence of actinic keratoses

When Is Squamous Cell Carcinoma Considered High Risk
Posted on February 4, 2015 in Skin Cancer, Mohs Micrographic Surgery, How to Protect Yourself From the Sun, Actinic Keratosis, Sunscreen, Surgery, Squamous Cell Carcinoma, Lips, Treatments, malignancy
Squamous Cell Carcinoma is the 2nd most common type of skin cancer after basal cell carcinoma. Although these tumors are generally not considered as aggressive as melanoma, it is often advised to treat them as soon as they are recognized or diagnosed. Although the chance on squamous cell carcinoma metastasizing is low, it is not zero, says Dr. Adam Mamelak, board-certified Dermatologist and Mohs Micrographic Surgeon in Austin, Texas. There are also a number of scenarios where the risk of spread can increase quite dramatically.
Squamous Cell Carcinoma and Metastases
Like other types of non-melanoma skin cancer, squamous cell carcinoma is considered locally aggressive, capable of invading into and destroying surrounding skin and tissues. The overall risk of metastasis with squamous cell carcinoma has been estimated at 2-6%. While this is considered low compared to other types of malignancies, it is still taken very seriously. Dr. Mamelak practices at Sanova Dermatology and the Austin Mohs Surgery Center where he uses Mohs micrographic surgery, surgical excision, and other treatments to remove cancerous tissue from skin.
