The world’s largest genetics study of ‘moliness’ has uncovered hundreds of genes that play a role in the growth of both moles and melanoma, a discovery that could lead to new ways to prevent and treat the deadliest form of skin cancer. These findings, published in Nature Communications, come from research by a team at QIMR Berghofer Medical Research Institute in Herston, Australia. The team found risk genes linked to biological pathways that could lead to the development of a mole or melanoma.
