Is a biopsy of temple necessary to diagnose headaches that travel across forehead above eyes?

No, a biopsy of the temple is not necessary to diagnose headaches that travel across the forehead above the eyes. Most headaches can be diagnosed based on a combination of the patient's history, symptoms, and a physical examination. In most cases, imaging studies such as MRI or CT scans are sufficient to identify any underlying causes of the headaches. A biopsy of the temple would only be necessary if there is suspicion of a specific underlying condition that requires tissue sampling for confirmation, which is rare in cases of headaches in that location.
