Can boosting tumor blood flow make cancer treatments work better?

This study tested whether temporarily blocking and then releasing blood flow to a skin cancer (basal cell carcinoma) could increase blood flow to the tumor. Twelve adults with this type of skin cancer had their tumor's blood supply briefly clamped during surgery, and blood flow was measured with a special laser camera. The goal was to see if this technique could later be used to improve oxygen levels in tumors, potentially making treatments like radiation or chemotherapy more effective.
