Zerodha Co-founder Nithin Kamath's wife Seema Patil has revealed in a blog that she was diagnosed with breast cancer in November 2021 despite being "the healthiest and fittest person" she knew. "The last few months...have been a blur and an emotional roller coaster. As cliché as it may sound, health really is wealth," Patil, who's Zerodha's whole-time director, wrote.
