Roeder was first diagnosed with the illness while in charge of the Hammers in April 2003.
As a player, Roeder represented the likes of Leyton Orient, Queens Park Rangers, Watford and Newcastle United and he last worked as a managerial advisor for Stevenage between 2016 and 2018.
Tributes have been pouring in for Roeder from his former clubs after news of his death came to light.
Former England international, Paul Gascoigne, a teammate of Roeder at Newcastle United, has shared some fond memories of his former colleague in an interview with Sky Sports.
"When I first started playing for Newcastle, Glenn was there, always supporting me. We would play snooker together and he would drop me off at home after training," Gascoigne said.
"When I got into the first team, he would be constantly talking to me on the pitch, telling me that I was playing well and where to go next on the pitch. For a young player, that is massive.
"When I moved to London, he drove me down there and parked up outside this huge house. It was a famous footballer's house. He said to me, 'look at that, this is what you are playing for.'
"He was the best captain I played for, the most honest, and he would put everybody before himself, making sure everybody was ready for the game before worrying about himself.
"He only got angry with me once, that was because I put the whistle off the kettle on his exhaust pipe and it cost him £360 to have the car checked out!
"Glenn was one of football's gentlemen and he will be sorely missed by his lovely family, his friends, and the whole of football."
