Dual-action cancer therapy
Patients with advanced tumors usually undergo a combination of treatments, including chemotherapy, surgery, and radiation.
Phototherapy is a newer treatment that involves implanting or injecting particles that are heated with an external laser. This raises the particles’ temperature enough to kill nearby tumor cells without damaging other tissue.
Current approaches to phototherapy in clinical trials use gold nanoparticles, which emit heat when exposed to near-infrared light.
