Which statement about radiation therapy's effect on wound healing after neck surgery is accurate?

Radiation therapy can delay tissue healing because it damages the cells and blood vessels needed for repair. It injures small vessels in the wound area, reducing blood flow and oxygen delivery, which slows fibroblast activity and collagen synthesis essential for forming sturdy granulation tissue and scar. This leads to slower wound closure and a higher risk of dehiscence or infection, especially after neck surgery where tissues are already stressed. Healing is not faster after radiation, and immediate tissue instability isn’t the typical description; the main issue is delayed and impaired healing. So the accurate statement is that radiation can delay tissue healing.
