In a new interview with The Mercury News, Tony Iommi was asked about the possibility of another BLACK SABBATH tour at some point in the not-too-distant future. He laughed and replied: "I wouldn't think so. But it's a strange thing with SABBATH — how many times we thought we were with Ozzy [Osbourne], then we had [Ronnie James] Dio, then back to Ozzy, then Dio again, and then Ian Gillan and Tony Martin and Dio and back to Tony Martin. It's gone backwards and forwards at different stages. So, you just never know.
"I think it's highly unlikely that we'd get back onstage again," he said. "It certainly wouldn't be touring. We'd only do so many shows, if anything.
"I would like to play with the guys again. But I can't see that happening.
"The reason we stopped touring in the first place was basically my fault, because I had to be careful of my health," Iommi explained. "When you book a tour — and it's always an 18-month tour — it doesn't sound a lot when you talk about it at first. But when you get out there, and you are touring, it's bloody hard work. And it wasn't particularly good for my health, because of the blood cancer. So, I said, 'Look, you know, this should the last tour, I think.' But I really do miss it. I really miss playing onstage. I miss seeing the audience."
Iommi revealed his cancer diagnosis in early 2012, shortly after SABBATH announced a reunion tour and album. He underwent treatment throughout the recording of the disc, titled "13", and the subsequent tour to promote it.
Iommi said in 2016 interview that "the lowest moment" for him was being diagnosed. He explained: "You automatically wind yourself up saying, 'That's it then,' but that is not always the case. When they tell you, you think, 'Oh God.' That was a low time. I have had a few low times in my life like everybody has, but that was one that stuck in the head."
Osbourne told The Pulse Of Radio in 2014 that Iommi never let his condition slow him down. "My hat goes off to him 'cause he really is Iron Man," he said. "I mean, that chemotherapy knocks you sideways, you know. I mean, when my wife had cancer a few years back, she was having three chemo things a month and it would knock the life out of — literally every time she'd have a treatment, she'd have a seizure. It's scary stuff. But he came down, plugged in and carried on. He's my hero, I swear to God he is."
The BLACK SABBATH guitarist successfully underwent an operation in January 2017 to remove a noncancerous lump from his throat.
"13" was the first album in 35 years to feature Osbourne, Iommi and bassist Geezer Butler all playing together.
In February 2017, SABBATH finished "The End" tour in Birmingham, closing out the quartet's groundbreaking 49-year career.
"The End" was SABBATH's last tour because Iommi can no longer travel for extended amounts of time.
