Actor Sanjay Dutt diagnosed with Stage 3 lung cancer

Taking to his Twitter and Instagram accounts, Dutt wrote, "I am taking a short break from work for some medical treatment. My family and friends are with me and I urge my well-wishers not to worry or unnecessarily speculate."

"With your love and good wishes, I will be back soon!" the actor assured fans.

He may fly down to the US for the treatment.

On Monday, Dutt came back home after undergoing treatment for two days at Mumbai's Lilavati Hospital. The actor's oxygen saturation level had dipped below normal, his doctor said.

He was hospitalized on August 8 after suffering from discomfort in chest and breathing problems.

It was initially presumed that Dutt might have contracted the novel coronavirus. But his COVID-19 test results came out as negative.

On Saturday night, Dutt took to social media to assure his fans that he was doing well and was under medical observation.

"With the help and care of the doctors, nurses and staff at Lilavati Hospital, I should be home in a day or two. Thank you for your well wishes and blessings (sic)," he had tweeted at the time.

Dutt, star of movies such as Rocky and the Munna Bhai series, was last seen in period-drama film Panipat.

He is now set to star in Mahesh Bhatt's Sadak 2, a sequel to 1991 hit movie Sadak, in which Dutt had also acted. It is set to premiere on Disney+ Hotstar on August 28.

He also has highly-anticipated KGF: Chapter 2 in the pipeline.
