Reference excerpt

Raymond Chang (born 1957), is an American physician specializing in integrative oncology. His research examines the use of Chinese herbs and repurposing of common drugs for cancer treatment and the integration of Western and Eastern medical practices.

Early life and education Chang was born in Hong Kong and later moved to the United States. He earned a Bachelor of Arts degree, magna cum laude, from Brown University, where he was elected to Phi Beta Kappa and Sigma Xi. He received his Doctor of Medicine from the Warren Alpert Medical School of Brown University. He completed his residency at Waterbury Hospital, affiliated with Yale University, and was a Kaiser Fellow at NewYork–Presbyterian Hospital/Weill Cornell Medical Center.

Career From 1987 to 1997, Chang was affiliated with Memorial Sloan Kettering Cancer Center. He served on the faculty of Weill Cornell Medical College from 1987 to 2014 and as an attending physician at NewYork–Presbyterian Hospital from 1997 to 2014. In 1997, Chang founded the Institute of East–West Medicine, a non-profit organization focused on integration of Western medicine and Asian healing traditions. He later established the Meridian Medical Group in New York City, which provides combined conventional and alternative treatments. In 2001, Chang chaired the First International Conference on Asian Therapies for Cancer in New York. Chang has been a member of the American Society of Clinical Oncology, the European Society for Medical Oncology, the Royal Society of Medicine, the European Society for Hyperthermic Oncology, and the American Society of Medical Acupuncture. He has served on editorial boards of Complementary and Alternative Medicine and Integrative Cancer Therapies, and on advisory boards for the National Cancer Institute's PDQ database and the Continuum Center for Health and Healing at Beth Israel Hospital in New York.

Research contributions Chang has authored over 70 academic papers with over 1000 citations. His research examines combination treatment strategies and drug repurposing for cancer and COVID-19, the integration of Eastern and Western medicine in oncology and immunology, the use of medicinal mushrooms and Chinese herbs in oncology, and the use of acupuncture in infertility. Since 2004, he collaborated with Dr. Thomas Nesselhut and Professor Fred Fändrich and published on dendritic cell vaccine research for cancer. He has proposed a "cocktail approach" to cancer treatment in 2008, advocating the use of multiple therapeutic agents and modalities simultaneously in combination, which he outlined in his 2011 book Beyond the Magic Bullet: The Anti-Cancer Cocktail. As part of a cocktail approach would be the use of repurposed drugs and Chang suggested that anti-parasitics such as anti-malarials could be a source of anti-cancer drugs. He also reviewed the use of Chinese herbs with chemotherapy for cancer and the use of metformin as an anticancer treatment. Chang is a licensed acupuncturist and published on acupuncture in reproductive medicine, including its application during in vitro fertilization (IVF). A 2003 review in Fertility and Sterility summarized possible effects of acupuncture on uterine blood flow, hormone regulation, and stress reduction. In 2022, Chang co-authored studies on the repositioning of chloroquine and hydroxychloroquine as potential prophylactic agents against SARS-CoV-2 and was one of the first to advocate the use of lactoferrin for COVID-19. He has also examined bioactive polysaccharides from traditional Chinese medicine herbs, including medicinal mushrooms, for their immunological effects. He has evaluated natural products such as mangosteen and soursop, noting that most evidence is limited to in vitro studies without established efficacy in humans.

Worked examples

Example 1 — a first encounter with Raymond Chang (physician)

Start with the simplest possible case. Write down what Raymond Chang (physician) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Raymond Chang (physician) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Raymond Chang (physician) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Raymond Chang (physician)

In research: Raymond Chang (physician) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Raymond Chang (physician) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Raymond Chang (physician) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 births, American internists, American medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Raymond Chang (physician) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
