I was diagnosed with stage 3 bowel cancer at Bkk hospital last year, cost around 70,000 baht for tests (Cigna insurance refunded 6,000) the surgery was quoted at 6-800,000 baht for surgery, this did not include any complications and recommended 6 rounds of chemo approx 500,000 baht. Decided to go home (uk) for treatment. Surgery 2 months after I arrived as they repeated all tests, Cancer downgraded to stage 2, no chemo recommended, so far so good.
