On average, the treatment requires one to five sessions that typically last about 20 minutes each, although the duration may vary. You will have one or more days off between sessions, with little to no recovery time so you can return to your normal activities.

This treatment option requires fewer sessions compared to conventional radiation therapy, which often requires daily treatments for six to eight consecutive weeks.

With ZAP-X you will experience:

  • Non-invasive treatment

  • No incisions

  • No invasive head frames

  • No pain

  • Simple outpatient procedure that often requires no anesthesia

  • Shorter treatment duration

  • Minimal number of treatments

  • Little to no recovery time
