Critically-acclaimed actor Irrfan Khan is back in India after undergoing treatment for neuroendocrine tumour in London.

The 52-year-old actor revealed last year in March that he was suffering from neuroendocrine tumour and has been away from the limelight since then.

"He is back in India from England," a source told PTI.

There were reports doing the rounds that Irrfan is undergoing treatment in the city-based hospital here, but the source denied saying, "He isn't here for any treatment." 

It is still unclear when the actor will be returning to work and start shooting for Hindi Medium 2, a sequel to his 2017 comedy drama.

Directed by Saket Chaudhary, Hindi Medium revolves around a couple who want to give their daughter the best education so that she becomes accepted by the elite in society. It also features Pakistani actress Saba Qamar. Dinesh Vijan’s production Hindi Medium 2 will flash-forward by a decade and will narrate the story of Irrfan’s character Raj.

Irrfan, who has delivered outstanding performances in films such as Paan Singh Tomar, Haasil, Maqbool and Piku, has also established himself in the West with movies like The Namesake, Life of Pi and Jurassic World.
