The rep added that the 57-year-old will not require more surgeries to treat the disease.

The musician had plans to tour Japan in November and will reschedule the dates for next year.

Van Halen is best known for hits including "Jump," "Why Can't This Be Love" and "When It's Love." The group released a new album, "A Different Kind of Truth," in February.
