The Indian cricketer, who won the Man of the Tournament award during India's World Cup triumph, had earlier voluntarily withdrawn himself from the Mumbai Test which ended today.
His mother Shabnam released a statement today stating he had been having bouts of coughing and vomiting but ignored the problem thinking it to be a stress-related issue.
The finger injury he sustained in England gave Yuvraj more time to assess the problem. Earlier, there were fears that the tumour could be malignant, Shabnam said.
"Further reports have indicated that the tumour is non-malignant and non-threatening and can be treated through proper medication and therapy. In medical terms, Yuvraj is now in a much better state and on his way to a full recovery," she said.
Yuvraj had earlier asked selectors not to consider him for the upcoming West Indies ODIs so that he could sort out his health issues.
