He is the head of player development at another of his former clubs.
Stewart played in all the tiers of England.
In the 2000-01 season, he scored 19 goals in the English premier league as Ipswich made the Uefa cup.
Stewart said in a statement that he intended to continue to enjoy his work in football and spend time with his family.

He returned to his home city and joined Bristol City, where he spent the last three years of his career as a coach.

Marcus had a good chat with the players this week, and was making them laugh, and said that he wants to be with the players.
Matt Taylor was a teammate of Stewart's at the club and says physical and mental strength will help him in the future.
"Maybe because I've played alongside people who've come across this situation in the past, Stephen and Marcus, so I've seen them at their best and sometimes we can't predict when illness and diseases will come," he said.
You only get to the top level of English football by being incredibly tough, physically and mentally.
He will do all he can to give himself the best chance of success.
