Recuperating from what he describes as a shock that only a cancer patient can understand, Indian cricketer Yuvraj Singh says he hopes to be back in action for the World Twenty20 Championships in September even though it would be a "big challenge" for him.

"Playing for India is going to be a huge challenge for me because the body has been under a lot of shock which nobody can understand except me," Yuvraj told 'ICC Cricket 360' show.

"Only a cancer patient can understand what he is going through. So it's going to be a big challenge for me to come back and play for India again," he added.

The all-rounder refused to commit to when he anticipates returning to the cricket field, stating that he is keen to avoid coming back prematurely.

"Well I can't really give a time-frame but I have to see how my body is recovering and how fast I can come on the field. Actually I don't want to rush and I don't want to come back at 75 per cent fitness. I might take six months, I might take two months. So I don't know. But the day I feel 100 per cent I surely will be back," he said.

Yuvraj, who is best remembered for his astonishing six sixes off one Stuart Broad over at the ICC World Twenty20 Championships in 2007, hinted that he may be available for selection for the next edition.

"I think (the) favourites are India because we've got the biggest hitters - biggest hitters in town that's what I want to say. Hopefully I should be back by then. "I'm not saying I'm the reason, it's just that I feel we have the strongest side and if we can sort out our bowling in T20s I'm sure we can be a strong unit. There are other strong teams like Australia, South Africa which always compete at the top level at world events," he said.

Yuvraj also spoke of his emotional battle against cancer.

"Initially it was hard to accept that a guy like me who is training six to seven hours a day, running around all the time as an athlete, can get diagnosed with something like this. It took a long time to sink in but eventually I made peace with it. I knew I have an issue and I have to sort it out," he said.

Yuvraj said the incredible support he received from Indian fans during his treatment made a huge difference to his recovery and spirit. "The support was overwhelming, especially from India.
