The 30-year-old, who went to US last month, has gone bald during the treatment, which will go on till the last week of March before the process of rehabilitation starts in April.

The dashing batsman had earlier got a message from US cycling legend Lance Armstrong, whose own inspirational triumph over cancer is well-documented, wishing him a speedy recovery.

"Message from @lancearmstrong makes me feel better! Thank you lance means a lot hope we can meet," tweeted Yuvraj. A photo of the Armstrong's message, posted by Yuvraj, read: "Yuvi, I want you to know that the entire LIVESTRONG team is here for you.”

"We say it all the time, and truly believe in it: Knowledge is power, Unity is strength, and Attitude is everything. Please know that we are here to help you and your family in any way possible. Go Yuvi!! Livestrong."

After being diagnosed with the illness, Yuvraj has not played competitive cricket since taking part in two of three home Tests against the West Indies in November.

India's star cricketer Yuvraj Singh undergoes treatment for lung cancer in US

Yuvraj Singh, who played a stellar role in India's ODI World Cup triumph last year, has been diagnosed with cancer and is undergoing chemotherapy in the United States, his physiotherapist said on Sunday.

The 30-year-old left-hander has been in the US since last month being treated for what was earlier claimed to be a tumour in the lungs, by his family.

But it has now been diagnosed as malignant and Yuvraj is currently undergoing chemotherapy in the Cancer Research Institute in Boston, his physiotherapist Dr Jatin Chaudhary said.

Dr Chaudhary however, assured that the ailment is curable and the batsman would be fit to resume cricket in May. His mother Shabnam Singh could not be reached while his father, former cricketer Yograj refused comments on the matter.

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

"It is not life threatening or career-threatening and it responds very well to chemotherapy. By the grace of God it was detected early and there is nothing to be scared of.

"The doctors decided that he would have to undergo chemotherapy and he travelled to the US on January 26. 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," he added.

Yuvraj, who was Player of the Tournament in the World Cup last year with 362 runs, 15 wickets and four Man-of-the-Match awards, has also been taking ayurvedic medicines to battle the disease.

"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.

Chaudhary said the detection of cancer was delayed by wrong diagnosis by an Indian hospital.

Meanwhile, the BCCI vice president Rajiv Shukla said that the Board was aware of Yuvraj's ailment and has been extending full support.

"We are concerned about his health and we wish him a speedy recovery. We hope that he will regain full fitness and comeback," Shukla said.

Yuvraj's teammate, paceman S Sreesanth also wished him a speedy recovery.

"It's sad to hear Yuvraj's ailment. Health is very important and I wish him very speedy recovery."

Tennis player Rohan Bopanna, Gujarat chief minister Narendra Modi, Jammu and Kashmir chief minister Omar Abdullah also wished him speedy recovery.

Yuvraj has played 37 Tests, scoring 1775 runs at an average of 34.80.

He has 8051 runs at an average of 37.62 from his 274-match ODI career, the highlight of which was his stellar role in India's World Cup triumph last year.

In 23 Twenty20s, Yuvraj has scored 567 runs at 31.50.
