Iron Maiden’s Bruce Dickinson is being treated for tongue cancer, a statement on the metal band’s website said.

The statement said Bruce Dickinson was diagnosed just before Christmas after a small cancerous tumor was found at the back of his tongue.

Bruce Dickinson has just completed a seven-week course of chemotherapy and radiology treatment and is expected to make a full recovery.

“As the tumor was caught in the early stages, the prognosis thankfully is extremely good,” the statement said.

“Bruce’s medical team fully expect him to make a complete recovery with the all clear envisaged by late May.”

The statement also asked for patience and respect for the singer, who is also a pilot and businessman, and his family’s privacy.

An update on his progress will be given by the end of May.

The tumor was discovered after a routine doctor’s check-up led to tests and a biopsy.

The statement concluded that “Bruce is doing very well considering the circumstances and the whole team are very positive”.

Iron Maiden finished a three-year world tour in July 2014 with a headline slot at the Sonisphere Festival.

While on stage Bruce Dickinson hinted a new album could be on its way.
