bjh369, the moderator suggested I contact you. My husband was diagnosed March 1, 2018, had radiation, took Temozolomide for 6 months concurrent with the Optune cap. We have been very pleased with the Optune cap. It takes awhile to get use to and it is a team effort but well worth it. The Novocore Company is very supportive and informative. Feel free to ask me any questions you might have.
