Overview
Other diagnostic studies for uveal melanoma include PET scan.
Other Diagnostic Studies
Positron Emission Tomography Scan
A baseline PET scan of the liver and other abdominal organs is advised in patients with a malignant uveal melanoma. Tumors that are too small will be identified by this study.
Biopsy
As almost all cases of uveal melanoma can be accurately diagnosed by the eye exam and imaging tests, a biopsy is not often needed. However, some doctors have started using biopsies to get a sample of the tumor for gene testing. This can help predict whether the melanoma is likely to come back outside of the eye at some point
- Biopsy of the uveal melanoma is not preffered because it can be hard to get a sample of the tumor without damaging the eye.
- Biopsy could possibly spread the tumor within or outside of the eye.
