What is the term for the therapy that uses high-intensity light to treat cancers?

The term for the therapy that uses high-intensity light to treat cancers is laser ablation. This technique involves using focused light to target and destroy cancerous tissue. The high intensity of the laser can precisely cut through the skin and tissues, minimizing damage to the surrounding healthy areas. This method can be advantageous due to its precision and less invasive nature compared to traditional surgical approaches.

In contrast, cryosurgery involves freezing tissue to destroy cancer cells, which does not utilize light but rather extreme cold. Radiofrequency ablation employs heat generated by radio waves to destroy tumors, which does not involve light either. Radiation therapy uses high-energy rays or particles to target and destroy cancer cells, but again, it is distinct from the focused light therapy utilized in laser ablation. Therefore, the correct answer accurately identifies the specific method that utilizes high-intensity light in the treatment of cancer.
