Description
Estimated cost for Squamous Cell Carcinoma Antigen at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The primary purposes of the SCC test include: 1. Monitoring the response to treatment in patients with squamous cell carcinoma, 2. Detecting recurrence of cancer after treatment, 3. Assessing the effectiveness of therapy, 4. Prognostic evaluation in certain types of cancer, 5. Distinguishing between different types of cancer, especially in the lung and head and neck regions.
Normal Range
The normal range for Squamous Cell Carcinoma Antigen (SCC) is typically less than 1.5 ng/mL, although this can vary slightly depending on the laboratory and the specific assay used.
Low Values - Possible Causes
Low values of SCC are generally not clinically significant and do not usually indicate a health problem. However, in some rare cases, it might be due to: 1. Laboratory error, 2. Recent treatment or surgery that has successfully reduced cancer markers, 3. Non-cancerous conditions where SCC levels naturally remain low, 4. Early stages of certain cancers before they start producing detectable levels of SCC, 5. Individual biological variation.
High Values - Possible Causes
High values of SCC may be caused by: 1. Squamous cell carcinoma, particularly in the lung, head and neck, cervix, and esophagus, 2. Other types of cancer such as cervical, prostate, or breast cancer, 3. Benign conditions like psoriasis, liver disease, or kidney failure, 4. Inflammation or infection, 5. Smoking, which can elevate SCC levels even in the absence of cancer.
