The band postponed a Halloween night gig in Birmingham following the singer's diagnosis, and the concert was just hours after he performed at the Mercury Prize awards ceremony in London.
A second show in Glasgow, scheduled for Friday, has also been axed.
A statement from the band reads: "We wish to apologise to all ticket holders for any inconvenience this has caused."
The two scrapped gigs will now take place on 20 and 21 November.
