While he does not like to be in the media glare, Emraan Hashmi does not shy away from promoting a good cause. We all know how he was devastated when his son, Ayaan was diagnosed with cancer two years ago. The doting dad spared no efforts for his son???s treatment taking him to Toronto, Canada where he got cured in six months for a tumour in his kidney. Since then, the actor has been at the forefront when it comes to promoting initiatives for cancer awareness. Last year, he wrote a book about the emotional struggles faced by his wife, Parveen and him during their son???s treatment.
