According to Yuvraj Singh's physiotherapist, Jatin Chaudhary, the all-rounder is undergoing treatment for cancer in the United States.

In November last year, Yuvraj was diagnosed with a "non-malignant tumour" in his left lung. It was first hoped that middle order man would be fit to take part in the current Tri-Series between India. Australia and Sri Lanka and later the Indian Premier League, however, he was forced to withdraw from both.

It has now been confirmed that 30-year-old is in the USA receiving chemotherapy.

"It is a rare tumour and is cancerous but it has been detected in stage one itself," said Chaudhary.

"Doctors had to decide whether to continue medication or go for chemotherapy but since parts of the tumour are just above the artery of his heart, there was a danger that while running it could burst. But it is 100% curable.

"The doctors decided that he would have to undergo chemotherapy and he travelled to the US on January 26. At the end of March, he would undergo a CT scan and should recover by then. After that it is just some rehabilitation in April before he is fit to be back on the field in May.

"After ayurvedic treatment only three cycles of chemotherapy are required. Initially when the cancer was diagnosed after a biopsy in October end, doctors feared that the treatment would be six cycles of chemotherapy," Chaudhary said.

"Thankfully no surgery is required, he is already a lot better than what he was and can't wait to be back on the cricket field."

Chaudhary explained that a delay in the correct treatment was as a result of an earlier misdiagnosis.

Neither Yuvraj's representatives nor the BCCI have commented on the matter.
