Celebrated lyricist Prasoon Joshi was in constant touch with late actor Irrfan Khan while he was going through a "really painful" treatment for his rare illness. Joshi says Irrfan's brave fight against the disease is inspiring.

Irrfan, who was diagnosed with a neuroendocrine tumour in 2018, passed away last week at the age of 54. He was admitted to Mumbai's Kokilaben Dhirubhai Ambani hospital with a colon infection. He succumbed to his ailment in hospital.
