His case is to be probed by health experts to see if the much-maligned vegetable can help others in their fight against cancer.
Mr Wiseman, who lives in Braunstone, Leicestershire, said doctors did not expect him to survive, but his recent scans show that his cancer has stopped growing. He attributes it to the glass of broccoli juice his wife prepares for him everyday. Ray said, 'I take this juice every day. I know it's done me good. I suppose it would be the same for everybody.'
His wife Joan, 72, started giving him the juice after a friend told her about the healing benefits of green vegetables.
For each half-tumbler dose she combines a broccoli head with some apples and carrots to improve the taste.
She said: 'We believe my husband's incredible luck is down to broccoli. I hope our experience can help other cancer sufferers.'
Scientists from Cancer Research UK have asked Joan Wiseman for the recipe, to further explore the vegetable's benefits.
Recent medical research has highlighted the possible cancer-beating powers of broccoli.
British researchers at the Institute of Food Research found that men who ate one daily portion of broccoli had altered patterns of gene activity in their prostates, suggesting that the chemicals in the vegetable might be able to reduce the risk of prostate cancer.
According to a report published in the British Journal of Cancer in 2006, natural chemicals found in certain vegetables, such as broccoli, cauliflower and cabbage, can enhance DNA repair in cells, which could help stop them becoming cancerous.
A spokesman for Cancer Research UK said: 'There's a lot of research that's focused on broccoli and the healing properties that the vegetable contains.'
Around 10,000 are diagnosed with bladder cancer every year in the UK. It is the fifth most common form of the disease and affects more men than women.
