Expression of specific gene differentiates moles from melanoma
Most melanomas are driven by mutations that spur out-of-control cell replication, while nevi (moles composed of non-cancerous cells at the skin surface) harbouring the same mutations do not grow wildly. However, changes in the level of gene expression can cause nevi to become melanomas. Dermatologists surmise that 30 to 40 percent of melanomas (approximately 30,000 […]
