Chromosomal Test By Molecular Biologists Determines Cancer Spread

A new biopsy test, created by molecular biologists, can tell ocular melanoma patients if theirs is the kind that will spread. Using very thin needles, surgeons collect cells from tumors and analyze them. If tumors are missing a copy of chromosome three, patients are at high risk of having their cancer spread. While there's no cure for ocular melanoma, patients who are at higher risk can be followed more closely and put on experimental treatments.
