Iron Maiden released a statement today revealing that vocalist Bruce Dickinson has been undergoing treatment for cancer, but suggested that things are looking alright for the singer and the band, labeling the prognosis as "extremely good" (from Rolling Stone). 

Dickinson apparently discovered the tumor, growing on his tongue, during a December medical examination. The growth was discovered early enough as to prevent it from becoming more serious. Although the band just now made an announcement, Dickinson has already completed seven weeks of chemotherapy and radiology treatment. Still, he won't be officially cleared until May and then he'll need a few more extra months to fully recover. So don't expect any Iron Maiden tour dates until late in 2015 at the earliest. 

"We would ask for your patience, understanding and respect for Bruce and his family's privacy until we update everyone by the end of May," said the band in a statement. "Bruce is doing very well considering the circumstances, and the whole team is very positive."

There's no word on how the tumor and its treatment could affect Dickinson's vocal ability in the long term, but based on the optimistic update from Iron Maiden, we'll assume that his powerhouse chops won't be affected negatively. 

Although most metal bands benefit from a noteworthy vocalist, few are as talented and relevant to their group's sound than Dickinson. Although the band had already gathered some degree of acclaim, it dropped original vocalist Paul Di'Anno after its second album Killers. That seemed like a questionable move to some, but they picked up Dickinson for what would become the band's masterpiece, Number of The Beast, where he quickly made himself noticeable thanks to his operatic treatment of "Hallowed Be Thy Name" and the legendary shriek of the title track.
