The sudden death of renowned Japanese novelist Keigo Higashino from colorectal cancer at 68 has resonated with millions of readers worldwide and put colorectal cancer, one of the world's most common cancers, back into the public spotlight.

Colorectal cancer, or bowel cancer, is the third most common cancer in the world, accounting for roughly 10% of all cancer cases globally, according to the World Health Organization.

Behind the headlines of grief lies a critical health message: colorectal cancer often develops silently from benign polyps over many years, making regular screening vital. In a previous CGTN interview, gastrointestinal cancer expert Dr. Li Guoxin stressed that lifestyle and early detection are key. He noted that a balanced diet, limiting processed foods and timely colonoscopies – especially for those over 40 or with a family history – can dramatically reduce risks.

We followed the journeys of colorectal cancer patients, their loved ones and the doctors who stand beside them, tracing difficult decisions and unwavering commitment – and the meaning of "till death do us part."
