The metal world's collective heart sank when it was announced in the beginning of 2012 that the godfather of metal himself, Tony Iommi, was battling lymphoma. However, the Black Sabbath guitarist has managed to persevere despite the diagnosis, and has started the new year with his latest health update.

Despite his battle with cancer, Iommi managed to record and release Black Sabbath's critically acclaimed and commercially successful comeback album, '13,' in addition to touring the world. That said, he has been limited in his touring runs due to his regular chemotherapy sessions.

Now, things are looking up in 2014, as Iommi reveals he'll be finishing up his regular treatment this year and should have more energy when Black Sabbath hit the road in the coming months.

Iommi's full blog post on his official website reads as follows:

Best Wishes for the New Year, after a such a brilliant 2013, it's going to be difficult to match it this year but we’ll be having a go.

I’d like the thank everyone who helped make the last year such a success, Ozzy and Geezer, the band’s management, Rick, Mike E and those who helped make the recording so good, the unseen work by our record label, the promotions team, my websites (Tracy, Joe & Bryce) and all of our touring crew, especially Mick and Kat who work with me personally.

We’ve some good things lined up for the coming year, firstly the Grammy’s, then some dates in the US and Canada, and in the summer a quick trip round Europe. I should also be finishing my regular treatment and I’m hoping to not get so tired, all positive.

Many thanks to you all for your continued support, we’d be nothing without you,

- Tony
