Aadesh, 48, has been in the Kokilaben Dhirubhai Ambani Hospital in Andheri for the last 44 days for treatment.
"He has been undergoing chemotherapy but he is not responding to it. So, the doctors have stopped giving him chemotherapy. They have an alternate theory. The doctors are trying to do their best and Aadesh is fighting it bravely," Aadesh's brother-in-law and composer Lalit Pandit told PTI.
His colleagues from the industry including megastar Amitabh Bachchan and superstar Shah Rukh Khan are keeping a check on his health.
People from music industry like Shaan, Sonu Nigam, Kumar Sanu, Alka Yagnik and Udit Narayan also visit him regularly. Also Shekar Kapur, Govind Nihalani, Poonam Dhillon and others had come to see him, he said.
Aadesh has composed music for hit films like "Chalte Chalte", "Baabul", "Baghban", "Kabhi Khushi Kabhie Gham", "Raajneeti" and "Dev" among others.
