I know Dr Suman Das since he was only 11 years old. We lived and studied together for 7 years. After our schooling he choose to be a doctor and I always liked computers.
Dr Suman Das is a radiation and clinical oncologist by profession and a great person to have as a friend. I don't know much about his profession but I know he is anti-cancer so in short he is a man of miracle who can pull you out of cancer. If you have any queries and concerns related to cancer then he is the right person to contact.
