'Healthiest person I knew': Emotional marathon moment makes Nithin Kamath share wife Seema’s cancer survival story

Zerodha founder and CEO Nithin Kamath recently shared an emotional post on social media after witnessing the Tata Mumbai Marathon, calling the experience deeply humbling. The sight of people with disabilities participating with enthusiasm moved him so much that it also led him to open up about a deeply personal chapter from his own life, his wife Seema Kamath’s battle with cancer.

The post quickly drew attention, not just for its emotional depth but also for the powerful message it carried about resilience, health, and gratitude.

“Their Energy Was Beyond Words,” Says Nithin Kamath

Taking to X, Nithin Kamath said the passion and determination shown by participants with disabilities at the marathon made him reflect on how often people complain about life.


He wrote that watching them run despite challenges was a reminder of how fortunate many of us are. The moment, he said, left him humbled and grateful.


Along with the post, Kamath shared a personal update, his wife Seema had completed the 10-kilometre run in just under an hour, nearly two-and-a-half years after surviving cancer.

Seema Kamath’s Cancer Diagnosis: “I Was the Healthiest Person I Knew”

In a follow-up post, Nithin Kamath shared a link to Seema’s blog titled “I am the healthiest person I know, and I got cancer!” In it, she opened up about being diagnosed with stage 2 breast cancer in November 2021.

Seema wrote that she had always considered herself extremely healthy and had no visible symptoms. The cancer was detected during a routine mammogram, something she now strongly advocates for.

She described the diagnosis as an emotional shock and said the months that followed were filled with uncertainty, fear, and strength she never knew she had.

Seema's Journey Through Treatment and Recovery

In her blog, Seema detailed the long and difficult journey that followed, from mastectomy to chemotherapy. She wrote honestly about the physical pain, exhaustion, and emotional strain that came with treatment.

One of the most touching moments she shared was when both she and Nithin decided to shave their heads together during chemotherapy. The gesture, she said, helped her feel less alone and made it easier to accept the changes her body was going through.

She also spoke about choosing to undergo treatment in India and praised the doctors and staff at Manipal Hospital, Bengaluru, for their care and support.

Spreading Awareness About Early Detection

A key message in Seema’s story is the importance of early diagnosis. She stressed that cancer can affect anyone, even those who appear perfectly healthy.

“Early detection is our best defence,” she wrote, urging people not to skip regular health check-ups or ignore medical screenings.

She also highlighted how cancer continues to be a taboo subject in India and why open conversations are necessary to remove fear and misinformation.

Social Media Reactions Pour In

Nithin Kamath’s post and Seema’s candid account received an overwhelming response online. Many users praised her courage and openness, calling her journey inspiring.

Several users commented on how the couple’s story changed their perspective on health and resilience, while others thanked them for encouraging conversations around cancer awareness and mental strength.
