Explainer | Hong Kong artist’s colon cancer diagnosis at 38 shows growing risk of it among the young
Helen Law mistook her colorectal cancer symptoms for signs of sleep deprivation. With cases in people under 50 rising, how to lower risk

Hong Kong artist and freelance writer Helen Law was just 38 when she was diagnosed with stage-three colorectal cancer.
She had been feeling tired and weak in the months leading up to the diagnosis, but was unaware that these were symptoms of cancer.
“I thought I was just sleep deprived,” Law, now 49, says.
“One day, after rushing to cross the street during my lunch break, I felt so out of breath that I had to sit and rest before walking back to my office.”

She saw a doctor, who ordered a blood test that confirmed she was anaemic – her red blood cell count was low. Follow-up tests including an endoscopy and colonoscopy revealed a malignant tumour in her colon.
