In the care process of cancer patients, there is often a gap period between initial treatments (such as surgery, chemotherapy, or radiotherapy) and regular follow-up visits. During this time, patients may not exhibit obvious symptoms, but residual or newly-formed tumor cells may persist, posing a risk of recurrence or metastasis. Traditional imaging techniques (such as CT or MRI) have limited sensitivity in detecting small lesions. Therefore, dynamic monitoring of micro-residual cancer cells during these gaps is crucial.

Hong Kong has one of the highest liver cancer incidence rates globally, largely due to chronic hepatitis B virus (HBV) infection, alcohol consumption, and fatty liver disease. However, early-stage liver cancer often presents no obvious symptoms, leading to late diagnoses when treatment options become more limited. This makes a highly sensitive and convenient early detection method crucial.

Lung cancer remains one of the most challenging malignancies worldwide due to its high mortality rate and often late-stage diagnosis. Early detection and personalized care strategies are critical in improving patient outcomes. RGCC’s Circulating Tumor Cell (CTC) testing offers a promising approach for monitoring lung cancer progression, treatment response, and recurrence risk. This article explores the latest clinical applications of RGCC CTC testing in lung cancer care.

When doctors diagnose cancer, they classify it into different stages to determine the tumor’s size, spread, and severity. Cancer staging not only helps in deciding the best treatment plan but also in predicting survival rates. Below is a detailed explanation of cancer stages from Stage 0 to Stage 4 in a simple and easy-to-understand way.

After completing cancer care, patients enter the recovery period, but this phase is not foolproof. Although care has ended, the risk of cancer recurrence still exists. Therefore, managing and continuously monitoring the recovery period is crucial. The frequency of monitoring will vary depending on the patient’s specific situation, cancer type, and individual health condition. Through regular monitoring, the medical team can detect potential signs of recurrence early and adjust care plans promptly to reduce the risk of recurrence and promote long-term recovery.
