Coin-sized photodynamic therapy device effectively treats basal cell carcinoma at home

A breakthrough pilot study in Brazil has demonstrated that a new coin-sized prototype photodynamic therapy (PDT) device can effectively and less painfully treat basal cell carcinoma (BCC) at home. Basal cell carcinoma accounts for 70% of skin cancer cases and its prevalence continues to increase. BCC is primarily caused by exposure to sun or following radiation therapy as a child.
