Green Day's Jason White has been diagnosed with tonsil cancer.

The 'Basket Case' rockers have asked fans to send ''love and positive healing vibes'' to the guitarist - who joined the band full-time in 2012 - as he battles the ''treatable'' strain of the disease.

The band said in a statement on their website: ''We have some news to report regarding our brother Jason White, and wanted you to hear it from us before word spread.

''Jason recently underwent a routine tonsillectomy, and his doctors discovered a treatable form of tonsil cancer. Thankfully they caught it early and he should make a full and speedy recovery. Please join us in sending him love and positive healing vibes during this time.''

Jason previously performed with Green Day frontman Billie Joe Armstrong's side project Pinhead Gunpowder in the early 1990s and became touring guitarist for the 'Warning' rockers in 1999.

He continued to perform with the group on the road at every subsequent tour, and was named a full time member in 2012 when they released trio of albums '¡Uno!', '¡Dos!' and '¡Tre!'.
