How soon after open surgery for sigmoid colon cancer would you be able to do a long haul flight?

After open surgery for sigmoid colon cancer, it's generally recommended to wait at least 4 to 6 weeks before considering a long-haul flight. This allows time for the body to heal and reduces the risk of complications such as blood clots. However, individual recovery can vary, so it's crucial to consult your healthcare provider for personalized advice based on your specific situation and recovery progress.
