Preparing for your S100 Malignant Melanoma
- 1For PSA, avoid ejaculation, vigorous cycling and prostate examination for 48 hours beforehand, and delay the test if you have a urinary infection.
- 2No fasting is required for most markers.
- 3Tell the nurse about any recent surgery, biopsy or inflammatory illness, all of which can raise several markers temporarily.
Sample for this test: venous blood sample (serum).
What S100 Malignant Melanoma measures
Laboratories file the S100 Malignant Melanoma under skin cancer detection, melanoma markers and S100 protein. The following sections set out how a tumour markers test of this kind is measured and read.
Tumour markers are substances — usually proteins — that can be produced in larger amounts by certain cancers, or by the body in response to them. Examples include PSA for the prostate, CA 125 for the ovary, CEA for the bowel, CA 19-9 for the pancreas, AFP and hCG for the liver and germ cells, and calcitonin or thyroglobulin for the thyroid. Newer approaches such as the Stockholm3 prostate test combine several markers with genetic and clinical data into a single risk score.
Who considers S100 Malignant Melanoma
- People often consider tumour marker tests if they have already been treated for a cancer and are monitoring for recurrence under specialist guidance.
- Men with urinary symptoms or a family history of prostate cancer commonly ask about PSA after discussing the pros and cons.
- Those with persistent bloating and pelvic discomfort may have CA 125 requested as part of an assessment.
- A specialist may recommend a marker to help characterise an abnormality already found on imaging.
- Some people request markers as part of a broad health check; these tests are not designed for that purpose, and the limitations are explained below.
Understanding your S100 Malignant Melanoma results
A raised tumour marker can indicate cancer but very frequently reflects benign causes — inflammation, infection, endometriosis, liver disease or smoking — and a normal value does not exclude cancer. Markers are most informative when tracked over time in someone with a known diagnosis, where a rising trend can suggest recurrence earlier than symptoms. Any elevation is flagged on the laboratory report and should be taken promptly to your GP or a clinician for assessment and, usually, imaging.
Tumour markers are not a screening test for cancer in people without symptoms; they are used alongside clinical assessment and imaging, and a result is not a diagnosis.
