Squamous Cell Carcinoma

Squamous cell carcinoma (SCC) is a type of cancer that arises from the squamous cells in the epidermis, the outermost layer of skin. It is the second-most common type of skin cancer, with more than 700,000 new cases diagnosed in the United States each year. SCC is most commonly caused by long-term sun exposure, but can also be caused by other factors such as smoking, HPV infection, and exposure to certain chemicals.

Risk Factors

The primary risk factor for SCC is long-term exposure to ultraviolet (UV) radiation from sunlight or tanning beds. Those who work outdoors, have fair skin, and have a history of frequent sunburns are at higher risk for developing SCC. Other risk factors include a history of smoking, HPV infection, and exposure to certain chemicals such as arsenic.

Those with a weakened immune system, such as those with HIV/AIDS or those undergoing chemotherapy, are also at increased risk of developing SCC. People who have had other forms of skin cancer, such as basal cell carcinoma or melanoma, are also at higher risk of developing SCC.

Signs and Symptoms

The most common sign of SCC is a spot on the skin that is red, scaly, and may be tender or itchy. It may also look like a wart or a sore that does not heal. The spot may bleed and crust over, and will usually be located on areas of the body most often exposed to the sun. Other signs include an open sore, a bump or nodule, or a thickened patch of skin.

If the SCC has spread to other parts of the body, there may be additional symptoms such as weight loss, fatigue, and pain in the affected area. It is important to seek medical help if any of these symptoms are present.

Treatment

The primary treatment for SCC is surgery to remove the affected area of skin. Other treatments may include radiation therapy, chemotherapy, or immunotherapy. Treatment will depend on the size and location of the tumor, as well as the overall health of the patient.

It is important to follow-up with regular skin exams to ensure that the SCC has not returned or spread. In some cases, additional treatments may be necessary if the cancer has spread. For those at high risk of developing SCC, preventative measures such as regular use of sunscreen and avoiding tanning beds can help reduce the risk.

Common Symptoms of Squamous Cell Carcinoma

• A firm, red nodule
• A flat lesion with a scaly, crusted surface
• A sore that does not heal
• A lesion that bleeds easily and does not heal
• A lesion that is tender to the touch
• A lesion that is growing in size
• A lesion that is changing in color or texture

When to See a Doctor

If you notice any of the above symptoms, it is important to see a doctor as soon as possible. Your doctor will be able to examine the lesion and determine if it is SCC. If it is, they will be able to recommend the best treatment plan for you.

Diagnosis and Treatment of Squamous Cell Carcinoma

If your doctor suspects that you have SCC, they may order a biopsy to confirm the diagnosis. A biopsy involves taking a small sample of the lesion and examining it under a microscope. If the biopsy confirms that you have SCC, your doctor will recommend a treatment plan. Treatment options for SCC include surgery, radiation therapy, and chemotherapy.

Preventing Squamous Cell Carcinoma

The best way to prevent SCC is to protect your skin from the sun. Wear sunscreen with an SPF of at least 30, and wear protective clothing when you are outside. Avoid tanning beds and sunlamps, and check your skin regularly for any changes.

Ultraviolet Radiation

Exposure to ultraviolet (UV) radiation is the most common cause of SCC. This type of radiation is found in sunlight and in tanning beds. People who spend a lot of time in the sun or who use tanning beds are at an increased risk of developing SCC. Wearing sunscreen and avoiding tanning beds can help reduce your risk.

Immune System Suppression

People with weakened immune systems are more likely to develop SCC. This includes people who have HIV/AIDS, those who have had an organ transplant, and those who take medications to suppress their immune system. If you have a weakened immune system, it is important to take extra precautions to protect your skin from the sun.

Chronic Skin Irritation

Chronic skin irritation can also increase your risk of developing SCC. This includes skin irritation caused by long-term exposure to certain chemicals, such as arsenic, and skin irritation caused by certain medical conditions, such as psoriasis. If you have a skin condition or are exposed to certain chemicals, it is important to take steps to protect your skin.

Tobacco Use

Tobacco use is also a risk factor for SCC. Smoking cigarettes and using other forms of tobacco can increase your risk of developing SCC. Quitting smoking and avoiding other forms of tobacco can help reduce your risk.

Genetics

Genetics can also play a role in your risk of developing SCC. People with certain genetic conditions, such as xeroderma pigmentosum, are more likely to develop SCC. If you have a family history of SCC, it is important to take extra precautions to protect your skin from the sun.

Conclusion

Squamous cell carcinoma is a type of skin cancer that can be caused by a variety of factors. Exposure to ultraviolet radiation, immune system suppression, chronic skin irritation, tobacco use, and genetics can all increase your risk of developing SCC. Taking steps to protect your skin from the sun and avoiding tobacco can help reduce your risk.
