Why is Squamous Cell Carcinoma Antigen (SCC) High? Causes, Symptoms, and What to Do

Squamous Cell Carcinoma Antigen (SCC) is a protein that can be measured in the blood, and it's often used to monitor certain types of cancer, particularly squamous cell carcinoma. High levels of SCC can indicate that cancer is present or that it might be progressing. Understanding why SCC levels are high and what this means can help you discuss your health with your healthcare provider.

What is Squamous Cell Carcinoma Antigen (SCC)?

SCC is a protein that is produced by squamous cells, which are flat cells found on the surface of the skin and in the lining of some organs. This antigen is often measured in the blood to help monitor squamous cell carcinoma, a type of cancer that arises from these cells. While SCC is most commonly associated with squamous cell carcinoma, elevated levels can sometimes be seen in other conditions as well.

Why High SCC Levels Matter

High levels of SCC in the blood can indicate the presence of squamous cell carcinoma or suggest that the cancer is not responding well to treatment. It's important to note that SCC is not used as a standalone diagnostic tool but rather as part of a broader assessment. Elevated SCC levels might also be seen in other conditions, such as certain inflammatory diseases or liver dysfunction, which can complicate the interpretation.

Causes of High SCC Levels

Several factors can cause SCC levels to rise:

• Squamous Cell Carcinoma: This is the primary condition associated with elevated SCC levels. The antigen is often used to monitor the treatment and progression of the cancer.
• Other Cancers: Some other cancers, such as cervical cancer, may also cause elevated SCC levels.
• Non-Cancerous Conditions: Conditions like psoriasis, eczema, and liver disease can sometimes lead to increased SCC levels.

Symptoms Associated with High SCC Levels

High SCC levels themselves do not cause symptoms, but they may be associated with symptoms of the underlying condition causing the elevation, such as:

• Skin Changes: In the case of squamous cell carcinoma, you might notice skin lesions or growths.
• Unexplained Weight Loss: This can occur with cancer.
• Fatigue: Often seen in both cancer and chronic inflammatory conditions.

How to Interpret SCC Test Results

If you have high SCC levels, your healthcare provider will consider these results alongside other tests and your overall health picture. It's important to discuss what the results mean in your specific context. Normal SCC levels can vary depending on the laboratory and the method used, so your doctor will interpret the results based on standard reference ranges.

Frequently Asked Questions

What is considered a high SCC level?

High SCC levels are typically above the reference range provided by the laboratory. Your doctor will interpret the results based on your specific situation and health history.

Can non-cancerous conditions cause high SCC levels?

Yes, conditions like psoriasis, eczema, and liver disease can also cause elevated SCC levels.

Is a high SCC level a definitive diagnosis of cancer?

No, a high SCC level alone does not diagnose cancer. It is used in conjunction with other tests and clinical evaluations.

When to See a Doctor

You should consult your healthcare provider if you receive a high SCC test result, especially if you have a history of cancer or are experiencing symptoms like unexplained weight loss, fatigue, or persistent skin changes. Your doctor can help determine the cause and discuss potential next steps.
