The British tennis star has struggled for form since memorably winning the US Open in 2021 and recently underwent surgery on her wrists and ankle in a bid to find a long-term solution to her fitness problems.
Becker experienced similar issues in his career after winning Wimbledon aged 17 in 1985 and is worried that Raducanu will find it hard to return to the top.
He told the Guardian newspaper: "The surgeries that she has had are, in my opinion, career-threatening.
"Having surgery on your playing wrist, and as a two-handed player, the other wrist – and then on your ankle – is tough to bear for a young woman."
Frequent coaching changes have also been suggested as a cause of Raducanu's struggles and Becker argues that long-term stability is needed if Raducanu wants to win another major title.
The German ace said: "I’m not in her inner circle so I don’t know all the things that went off, although I’ve seen the coaching changes.
"But as a young woman, all of a sudden being on top of the mountain, you have to really dig in and find the resources and the team around you to guide you through the next 10 years.
"Its about mindset and talent, team, approach and circumstances. She’s not the first one who wasn’t able to do it. And she won’t be the last. But if she was good enough to win a Grand Slam once, she’s good enough to win one again."
