After being accepted as a member of the Royal College of Physicians (United Kingdom), Dr. Zee worked at the Royal Marsden Hospital in London before completing specialist training in Medical Oncology at the National University Hospital, Singapore.
He subsequently underwent fellowship training at The Christie Hospital and Paterson Institute for Cancer Research in Manchester, where his focus was on anti-cancer drug development.
Before moving to his current practice, he was a Consultant Medical Oncologist at the National University Cancer Institute, Singapore.
Importance of early detection
Early detection through screening can significantly improve treatment outcomes and increase chances of survival, and better, can help one check for cancer for those who do not display symptoms yet.
“Cancer, if undiagnosed or untreated, has the potential to grow and spread to distant organs.
This, in turn, can result in symptoms and failure of the affected organ or organs,” said Dr. Zee.
Types of screening tests include physical examinations and history, laboratory tests like blood tests and imaging procedures. However, there are only cancers where screening can be possible and recommended like breast, cervical, colorectal and prostate cancers. Dr. Zee emphasized that not all can have effective screening tests.
In addition, screening can also help detect and remove abnormalities that can cause cancer if left untreated. For instance, during colonoscopy screening for colorectal cancer, if polyps are detected, they can be removed immediately to prevent them from becoming cancerous.
Dr. Zee, an expert in general medical oncology with a special interest in colorectal cancer, also emphasized that in east and Southeast Asian countries, researchers have observed a significant rise in colorectal cancer rates. Early detection, timely diagnosis, appropriate treatment and regular follow-up care are essential for improving survival rates and quality of life.
“Early diagnosis, even before the onset of symptoms, is crucial in allowing doctors to deliver more effective treatment with potentially higher rates of cure. This underlines the importance of screening for colorectal cancer,” he remarked.
