Squamous Cell Carcinoma (SCC)
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.
Symptoms
Common Symptoms of SCC
- A firm, red bump on the skin that may be tender to the touch
- A scaly, crusty patch of skin that may bleed or ooze
- A sore that does not heal or that bleeds easily
- A wart-like growth that may be itchy or painful
- A sore throat or hoarseness that does not go away
- A lump in the neck or throat
- Difficulty swallowing
- A persistent cough
- Shortness of breath
If you experience any of these symptoms, it is important to see a doctor as soon as possible. Early diagnosis and treatment of SCC can help prevent it from spreading to other parts of the body.
Causes
Exposure to Ultraviolet (UV) Radiation
Exposure to ultraviolet (UV) radiation from the sun or tanning beds is one of the most common causes of SCC. UV radiation damages the DNA in the skin cells, which can lead to the development of SCC. It is important to protect your skin from UV radiation by wearing sunscreen, hats, and protective clothing when outdoors.
Weakened Immune System
A weakened immune system can make it more difficult for the body to fight off abnormal cell growth, which can lead to SCC. People with weakened immune systems, such as those with HIV/AIDS or those undergoing chemotherapy, are at an increased risk of developing SCC.
Chronic Skin Irritation
Chronic skin irritation can also increase the risk of SCC. This includes skin irritation caused by long-term exposure to certain chemicals, such as arsenic, or from wearing tight clothing that rubs against the skin. People who have had skin grafts or skin ulcers are also at an increased risk of developing SCC.
Tobacco Use
Tobacco use is another risk factor for SCC. Smoking cigarettes or using other forms of tobacco can damage the skin cells and increase the risk of SCC. Quitting smoking can help reduce the risk of SCC.
HPV Infection
Human papillomavirus (HPV) is a virus that can cause certain types of cancer, including SCC. HPV is spread through sexual contact and can increase the risk of SCC in both men and women.
Conclusion
Squamous cell carcinoma (SCC) is a type of skin cancer that can be caused by a variety of factors, including exposure to ultraviolet (UV) radiation, weakened immune system, chronic skin irritation, tobacco use, and HPV infection. It is important to protect your skin from UV radiation and to quit smoking to reduce the risk of SCC.

Lifestyle
1. Wear Sunscreen
One of the best ways to protect yourself from SCC is to wear sunscreen every day. Look for a sunscreen with an SPF of 30 or higher and make sure it is broad-spectrum, meaning it protects against both UVA and UVB rays. Reapply sunscreen every two hours, or more often if you are swimming or sweating.
2. Avoid Tanning Beds
Tanning beds are a major source of UV radiation, and using them can significantly increase your risk of developing SCC. If you want to get a tan, opt for a spray tan or self-tanning lotion instead.
3. Cover Up
When you are out in the sun, make sure to cover up with clothing, a hat, and sunglasses. Look for clothing that is labeled as “sun protective” and has an ultraviolet protection factor (UPF) of at least 30. This type of clothing is designed to block out UV rays.
4. Stay in the Shade
Whenever possible, try to stay in the shade when you are outside. This is especially important during the middle of the day, when the sun’s rays are the strongest. If you are going to be outside for an extended period of time, make sure to take breaks in the shade.
5. Check Your Skin Regularly
It is important to check your skin regularly for any changes or new growths. If you notice anything unusual, make an appointment with your doctor right away. Early detection is key to successful treatment of SCC.
Conclusion
By following these lifestyle tips, you can reduce your risk of developing SCC. Remember to wear sunscreen, avoid tanning beds, cover up, stay in the shade, and check your skin regularly. If you have any concerns, make sure to talk to your doctor.
