Dr. Chang points out that breast cancer is hard to detect by touch in the early stages. X-rays are much more effective, but because Asian women's breasts tend to be smaller, the pain associated with having them squeezed in vice-like X-ray machines has turned many women away from having them X-rayed a second time. He hopes that the health authorities will consider offering ultrasound examinations as part of free regular screening programs.
張金堅指出，早期乳癌很難經由觸診發現；效果較佳的乳房 X 光攝影，因東方婦女的乳房較小，用力壓夾就會產生極大的疼痛感，讓許多婦女做過一次後就視為畏途，將來乳房超音波檢查是否列入定期免費篩檢項目，應是可以考慮的選項。
