When Dr. U.S. Vishal Rao, a Bengaluru-based oncologist, saw how many stage four throat cancer patients struggled to afford expensive imported voice prosthesis to be able to speak again, he decided to do something about it. Together with his friend Shashank Mahesh, Dr. Vishal invented an incredibly low-priced voice device called 'Aum Voice Prosthesis.' Costing only $1, the device has helped 200 people to regain their voices and is expected to reach thousands more in the coming years, with the World Health Organization and nine other countries already expressing interest in the product. "The pain of cancer is the same for all, whether one is rich or poor," reasons Dr. Vishal. Read on to learn more about his inspiring mission and the lives he's changed.
