The health education talk to the general public at the Hong Kong Central Library on May 28th, 2018 was a success. Dr. Amy Chang gave a thorough presentation to emphasize that Next-Generation Sequencing (NGS) tests could become a new benchmark in early cancer diagnosis. As targeted and immune drugs are becoming more popular, Dr. Chang aims to raise awareness on NGS as an important diagnostic tool for selecting suitable drug candidates. Dr. Chang also quoted a few examples of clinical cases using NGS. Strong audience interest was provoked to ask many stimulating questions and informative answers were provided.
