Roger Bellham had been suffering from lung and liver cancer and died peacefully at James Paget University Hospital at about 8.30am.
The 71-year-old from Gunton was elected mayor at a meeting of the Lowestoft Charter Trustees at the end of June, when he said he was “proud and overjoyed” to be made mayor for the first time.
Mr Bellham was a member of the Labour party and represented St Margaret’s Ward on Waveney District Council.
A former council groundsman, he was also the chairman of Lowestoft in Bloom and the Lowestoft-based charity Aid and Assist, which supports people with disabilities and learning difficulties through a range of projects.
Fellow district councillor and Waveney Labour party leader Sonia Barker said it as with deep sadness that she had learned of the death of Mr Bellham.
“We have all lost a distinguished comrade and friend who served his beloved Lowestoft as a true public servant over many years,” she said. “He will be greatly missed.”
Waveney leader Colin Law said he was deeply saddened to hear of the death of Mr Bellham.
He said: “He was an excellent and well-liked ward councillor and a dedicated mayor of Lowestoft.
“On behalf of the council, I would like to offer my deepest condolences to all of Roger’s family and friends.”
Mr Bellham was diagnosed with cancer in October 2013 and underwent a major operation to remove both of his kidneys as well as his bladder and prostate.
He spent two weeks in intensive care and had dialysis three mornings a week.
He discovered the cancer had returned last month.
Mr Bellham’s wife Jo and sons Steven, Michael, Jonathan and Scott paid tribute to him today.
They said: “Being mayor was the highlight after the year he had previously had.
“He loved every moment of it.
“He has done a lot for the community over the years
“We are all deeply saddened but also very relived. It was a long battle.”
Mr Bellham’s have asked for donations to the Louise Hamilton Centre and the renal unit at JPUH in lieu of flowers.
