Actor Emraan Hashmi recalled the tough phase in his life when his young son fought cancer. The actor recently shot for a Karamveer Special episode of "Kaun Banega Crorepati 11" with Founder and CEO of Cuddles Foundation, Purnota Dutta Bahl, who is considered as a messiah for poor kids suffering from cancer.

"I have been following Purnota's work since many years because my son was diagnosed with cancer five years ago, and later my mother too became a victim of the disease. A family is emotionally devastated when somebody from that family is diagnosed with cancer," said Emraan.
