Read our Melanoma research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a new diagnostic device called Cytophone that scans your blood vessels using a safe laser beam to look for melanoma cancer cells circulating in your blood. The device is designed to catch melanoma spread much earlier than current blood tests, potentially before you have symptoms or visible tumors. Early detection could mean treatment when the disease is still manageable.
Most melanoma deaths happen when cancer cells break free from the original tumor, travel through the bloodstream, and spread to other organs. Current blood tests can only detect this spread in advanced cases. This trial exists to see if Cytophone can catch these circulating cancer cells much earlier—when treatment is more likely to work—by analyzing a much larger volume of blood than existing tests.

Your participation would take about 60–90 minutes total. First, you'll have a 30-minute preparation phase where staff will use ultrasound to locate a blood vessel in your arm, take a photo of the skin above it, and position a small scanning probe. Then, the actual Cytophone scan takes 30–60 minutes—during this time, a safe laser beam will gently scan the blood vessel to look for melanoma cells in your blood. The procedure is noninvasive and painless.
