Squamous cell cancer is a type of skin cancer that many people do not know much about. It is a dangerous form of cancer that develops in the squamous cells of the skin, which are thin, flat cells that make up the outermost layer of the skin. Squamous cell cancer is commonly found on sun-exposed areas of the body, such as the scalp, face, ears, lips, and hands. However, it can occur anywhere on the body, including inside the mouth and anus.
Unfortunately, squamous cell cancer is one of the most common types of skin cancer. It affects over one million people in the United States each year and can be a serious health concern. Some of the symptoms of squamous cell cancer include a red, scaly patch on the skin that may bleed or turn into an open sore, a wart-like growth or a white band-aid type growth, and a sore that does not heal. It is essential to get regular skin checks from a board-certified dermatologist if you have a history of skin cancer or if you notice any of these symptoms on your skin.
Thankfully, early detection and treatment of squamous cell cancer can be highly effective. If you notice any unusual changes in your skin, it is important to consult with your dermatologist and get a full skin exam. With the right treatment plan, you can quickly take control of your skin health and enjoy all the summer fun that is waiting for you.
What are the causes of squamous cell cancer?
Squamous cell carcinoma (SCC) is a type of cancer that affects the squamous cells found in the skin, as well as the lining of some organs like the esophagus, lungs, and bladder. It is the second most common type of skin cancer, accounting for about 20% of all cases. The main cause of SCC is exposure to ultraviolet (UV) radiation from the sun, which damages the DNA of skin cells and causes mutations that lead to cancer.
Other factors that increase the risk of developing SCC include:
- Having fair skin, light-colored hair, and blue, green, or gray eyes
- A history of frequent sun exposure or sunburns, especially during childhood
- Living in regions with high levels of sunlight, such as tropical or subtropical areas
- Using tanning beds or sunlamps
- Having a weakened immune system, either due to a medical condition or medication
- A history of radiation therapy
- Exposure to certain chemicals, such as arsenic and some industrial agents
In addition to these risk factors, there are also genetic factors that may influence the development of SCC. Certain inherited conditions, such as xeroderma pigmentosum and albinism, make people more susceptible to UV damage and skin cancer.
Symptoms of Squamous Cell Cancer
Squamous cell cancer is a form of skin cancer that arises when squamous cells, which are found in the outer layer of the skin, begin to grow uncontrollably. It is one of the most common types of skin cancer, accounting for about 20% of all cases.
There are several symptoms of squamous cell cancer that you should be aware of, including:
- A sore or lump that doesn’t heal or that grows larger over time
- A patch of skin that is scaly, crusty, or bleeds easily
- A growth that has a sunken center or raised border
If you notice any of these symptoms, it’s important to see a dermatologist as soon as possible. They will be able to examine the area and perform a biopsy if necessary.
Diagnosing Squamous Cell Cancer
Diagnosing squamous cell cancer typically involves a combination of a physical examination and a biopsy. During the physical exam, the dermatologist will examine the affected area and ask you questions about any symptoms you may be experiencing. If they suspect that the growth could be cancerous, they will perform a biopsy.
A biopsy involves removing a small sample of tissue from the growth and sending it to a lab for analysis. The lab will examine the tissue under a microscope to determine whether it is cancerous and, if so, what type of cancer it is.
Treatment Options for Squamous Cell Cancer
Treatment for squamous cell cancer will depend on the size and location of the growth, as well as other factors such as your age and overall health. In some cases, the growth may be small enough that it can be treated with a simple excision.
In other cases, more aggressive treatment may be necessary. This could include radiation therapy or chemotherapy.
The table below provides an overview of some common treatment options for squamous cell cancer:
| Treatment | Description |
|---|---|
| Surgical excision | The cancerous growth is removed with a scalpel |
| Mohs micrographic surgery | A specialized technique that involves removing thin layers of tissue until no cancerous cells are left |
| Radiation therapy | High-energy radiation is used to kill cancer cells |
| Chemotherapy | Drugs are used to kill cancer cells |
If you have been diagnosed with squamous cell cancer, it’s important to work closely with your healthcare team to determine the best course of treatment for your individual needs.
Staging and diagnosis of squamous cell cancer
Squamous cell cancer is a type of skin cancer that develops from the squamous cells that make up the outer layer of skin. It is the second most common type of skin cancer and can occur anywhere on the body, although it is most commonly found on areas of skin that have been exposed to sunlight, such as the face, ears, neck, and back of the hands.
When it comes to staging and diagnosing squamous cell cancer, there are several factors that doctors take into consideration. These may include the size and location of the cancer, as well as whether it has spread to nearby lymph nodes or other parts of the body.
Diagnosis of squamous cell cancer
- Skin biopsy: A sample of the skin is removed and examined under a microscope to determine whether cancer cells are present.
- Imaging tests: If there is concern that the cancer has spread beyond the skin, imaging tests such as X-rays, CT scans, or MRI scans may be used to look for signs of cancer in the lymph nodes or other parts of the body.
- Lymph node biopsy: If lymph nodes in the area of the cancer appear enlarged, a sample may be removed and checked for cancer cells.
Staging of squamous cell cancer
Staging refers to the process of determining the extent and severity of a cancer, which is important for making decisions about treatment. The staging of squamous cell cancer is based on a combination of factors, including:
- The size and depth of the cancer
- Whether the cancer has invaded nearby tissues or organs
- Whether the cancer has spread to lymph nodes or other parts of the body
The following table outlines the different stages of squamous cell cancer:
| Stage | Description |
|---|---|
| Stage 0 | The cancer is only in the top layer of skin and has not invaded deeper tissues |
| Stage I | The cancer has invaded deeper layers of skin but is still localized to the area of the original cancer |
| Stage II | The cancer has invaded nearby tissues or organs, but has not spread to lymph nodes or other parts of the body |
| Stage III | The cancer has spread to nearby lymph nodes or tissues, but not to distant parts of the body |
| Stage IV | The cancer has spread to distant parts of the body, such as the lungs or liver |
Knowing the stage of the cancer helps doctors determine the appropriate treatment plan and predict the outlook for the patient.
Treatment options for Squamous Cell Cancer
When it comes to squamous cell cancer, there is no one-size-fits-all treatment plan. The right type of treatment for you will depend on the size and location of the cancer, whether it has spread, and your overall health. Your doctor will discuss the different options with you and help you make a decision.
- Surgery: This is often the first treatment option for squamous cell cancer. The surgeon will remove the cancerous tissue along with a margin of healthy skin to reduce the risk of the cancer coming back. In some cases, a skin graft may be needed to cover the area.
- Radiation therapy: This treatment involves using high-energy radiation to kill cancer cells. It is often used in conjunction with surgery or if surgery is not an option. Radiation therapy can be done externally or internally, depending on the location of the cancer.
- Chemotherapy: This treatment uses drugs to kill cancer cells. It is often used in advanced cases of squamous cell cancer when the cancer has spread to other parts of the body and surgery is not an option.
If the cancer has not spread beyond the skin, there is a high cure rate. Even if the cancer has spread, treatment can still be effective, especially if it is caught early. It is important to follow up with your doctor regularly after treatment to monitor for any recurrence.
In addition to these treatments, there are also some newer therapies being tested for squamous cell cancer. These include:
| Treatment | Description |
|---|---|
| Immunotherapy | This treatment uses the body’s own immune system to fight cancer cells. It works by strengthening the immune system’s ability to recognize and attack cancer cells. |
| Targeted therapy | This treatment uses drugs that target specific genes or proteins that are involved in the growth and spread of cancer cells. |
These newer therapies are not yet widely available, but they may become an important option for treating squamous cell cancer in the future.
Ways to prevent squamous cell cancer
Squamous Cell Carcinoma (SCC) is the second most common type of skin cancer and is caused by abnormal growth of the cells in the outer layer of the skin – the squamous cells. While this type of cancer is treatable if detected early, it’s always better to practice prevention measures to minimize the risk of developing it. Here are five ways to prevent squamous cell cancer:
- Use sunscreen: Applying a broad-spectrum sunscreen with an SPF of 30 or higher can help prevent the ultraviolet (UV) rays from penetrating your skin and causing skin damage. Be sure to apply sunscreen 15 minutes before going outdoors and reapply every two hours or after swimming or sweating.
- Avoid tanning beds: Tanning beds expose you to harmful UV rays, which increase your risk of developing skin cancer, including SCC.
- Wear protective clothing: Wear clothing that covers your skin, such as long-sleeved shirts and pants, and wide-brimmed hats to shield your face, neck, and ears from the sun’s rays.
- Check your skin regularly: Examine your skin regularly to detect any changes such as new moles, growths or skin spots that could indicate SCC or other types of skin cancer. If you notice any changes, see a dermatologist immediately.
- Avoid exposure during peak sun hours: UV rays are at peak intensity from 10 a.m. to 4 p.m. If possible, avoid sun exposure during these hours. If you can’t avoid being outdoors, stay in the shade or bring an umbrella with you.
Protecting yourself from squamous cell cancer
By taking the necessary precautions, you can reduce your risk of developing squamous cell cancer significantly. Protecting your skin from harmful UV rays and monitoring any changes in your skin can also ensure that SCC is detected early and treated effectively.
UV Index Table
| UV Index | Risk | Sunburn Potential |
| 0-2 | Low | Minimal |
| 3-5 | Moderate | Medium |
| 6-7 | High | High |
| 8-10 | Very High | Very High |
| 11+ | Extreme | Extreme |
Checking the UV index before going outdoors can help you plan your activities and decide on the necessary protection measures to take to reduce your risk of sunburn and skin cancer.
The Difference Between Squamous Cell and Basal Cell Cancer
Squamous Cell Cancer and Basal Cell Cancer are two of the most common types of skin cancers. Both types of cancer start in the top layer of skin cells but have different characteristics. Squamous cells are flat cells that make up the outer layer of the skin, while basal cells are located just below the squamous cells in the deepest part of the epidermis.
- Causes: The primary cause of both Basal Cell and Squamous Cell skin cancers is exposure to UV radiation such as the sun’s rays or tanning beds. Other factors that can lead to skin cancer include exposure to radiation, exposure to some chemicals, and having a weakened immune system.
- Appearance: Squamous Cell Cancer usually appears as a firm, red nodule or a flat lesion with a scaly or crusty surface. Basal Cell Cancer, on the other hand, often appears as a translucent, pearly bump or a flat, pink, or flesh-colored lesion with a waxy texture.
- Location: Squamous Cell Cancer is typically found on areas of the body exposed to the sun, such as the face, ears, and hands. Basal Cell Cancer is also more common in sun-exposed areas, but it can also occur in non-sun-exposed areas such as the scalp, chest, and back.
Squamous Cell and Basal Cell skin cancers can also spread to other parts of the body if left untreated. Squamous Cell Cancer is more likely to spread more quickly than Basal Cell Cancer, but both types of cancer can be treated successfully if detected early and properly treated.
If you notice any skin changes that worry you, such as new growths, sores that don’t heal, or changes in existing moles, make an appointment with your doctor or dermatologist immediately. The earlier you detect any possible cancerous growths, the less invasive treatment you will need.
| Basal Cell Cancer | Squamous Cell Cancer |
|---|---|
| Occurs most often on the face, neck, and other areas frequently exposed to the sun | Occurs most often on body parts exposed to the sun, such as the hands, arms, and face |
| Pearly or waxy bumps that look like a flesh-colored mole or a raised pink patch | Firm, red nodule or a flat lesion with a scaly or crusty surface |
| Rarely spreads to other parts of the body | More likely to spread to other parts of the body than Basal Cell Cancer |
Both Basal Cell and Squamous Cell skin cancers are treatable when detected early. A dermatologist can discuss the best treatment options for each individual patient.
How common is squamous cell cancer?
Squamous cell cancer (SCC) is the second most common type of skin cancer after basal cell cancer (BCC). According to the Skin Cancer Foundation, there are approximately 1 million new cases of SCC diagnosed in the United States each year. This accounts for about 15–20% of all skin cancers.
- The incidence of SCC has been increasing over the years due to factors such as aging, increased outdoor activities, and tanning bed use.
- SCC usually appears in areas that are frequently exposed to the sun, such as the face, ears, neck, and hands. However, it can appear anywhere on the body, including the genital area and inside the mouth.
- People with fair skin, light eyes, and a history of sunburns or excessive sun exposure are at a higher risk of developing SCC.
SCC is more commonly diagnosed in men than in women and is generally seen in people over the age of 50. However, it can occur in younger individuals, especially those who have been exposed to excessive ultraviolet (UV) radiation.
| SCC Incidence by Age Group | Percentage |
|---|---|
| Under 40 | 4% |
| 40–59 | 32% |
| 60–79 | 60% |
| Over 80 | 4% |
If you notice any changes in your skin, such as the appearance of a new growth, a sore that doesn’t heal, or a change in the size or color of an existing mole, it is important to see a dermatologist as soon as possible. Early detection and treatment of SCC can lead to a better prognosis and successful treatment outcomes.
