Recently actor Emraan Hashmi’s four-year-old son Ayan was diagnosed with first-stage cancer and underwent a surgery. He is likely to go for chemotherapy sessions abroad. Apparently cricketer Yuvraj Singh who had earlier been diagnosed with a cancerous tumour in his left lung and underwent chemotherapy in the US has given reference to the actor for his son’s treatment abroad. Ayan had a successful surgery on January 15 and is recovering after a malignant tumour was removed from his kidney. 'He is likely to be discharged tomorrow. As the surgery was successful they are likely to go abroad for treatment… for chemotherapy' sources
