预防癌症復發
In 2015, a study from Johns Hopkins University published in Science sparked widespread discussion. Researchers suggested that most cancers are not entirely caused by external environmental factors, but rather by random “bad luck” gene mutations during cell division. These mutations are like random traffic accidents—unavoidable to some extent.
For many, a cancer diagnosis represents a major life turning point, symbolizing both the risk of mortality and emotional strain on families. While medical advances in Hong Kong have improved survival rates, psychological stress and trauma remain significant challenges for cancer patients.
Blood tests are an essential part of cancer treatment and monitoring. In Hong Kong, doctors routinely order blood tests during chemotherapy, targeted therapy, immunotherapy, or follow-up periods to assess the patient’s health, immune function, organ function, and tumor changes.
Many cancer patients worry that sugar may worsen their condition. In fact, all cells — both normal and cancerous — require glucose for energy. However, cancer cells often rely on a unique metabolic pathway called the Warburg Effect, where they rapidly break down glucose through anaerobic respiration, enabling faster growth.
Circulating Tumor Cells (CTCs) are cancer cells that break away from the primary tumor, enter the bloodstream, and travel to distant organs, where they may grow and form metastases. CTCs are considered critical markers of cancer recurrence and progression.
This is a common concern among cancer patients. Many have heard that “sugar feeds cancer” and therefore consider cutting out sugar completely. In reality, all cells—including healthy cells and cancer cells—require glucose as an energy source.
Research by the World Health Organization shows that about 50% of cancer cases and recurrences can be prevented through a healthy lifestyle. Aside from the few cases caused by genetic inheritance, most cancers are closely linked to poor diet, lack of exercise, obesity, stress, and unhealthy habits.
Many cancer survivors maintain unhealthy eating and exercise habits even after treatment. Studies show that cancer survivors have a high risk of developing metabolic syndrome. Metabolic abnormalities—such as high blood sugar, abnormal cholesterol, obesity, and insulin resistance—can increase the risk of cancer recurrence and elevate the likelihood of cardiovascular disease and secondary cancers.
