Helping you understand “what these changes might mean” — and a gentle reminder not to worry excessively
Pancreatic cancer is one of the relatively high-incidence and poorer-prognosis cancers in Hong Kong, often associated with smoking, long-term alcohol consumption, high-fat diets, diabetes, chronic pancreatitis, or family history.
Early symptoms of pancreatic cancer are extremely subtle and frequently mistaken for stomach pain, indigestion, or “stomach gas”, causing many patients to delay seeking medical care.
However, early detection of pancreatic cancer is crucial for treatment success — prompt identification and examination can significantly increase surgical opportunities and survival rates.
The following outlines common early warning signs of pancreatic cancer, aimed at helping you distinguish “normal” from “abnormal”. Please remember: these symptoms do not necessarily indicate pancreatic cancer — most have benign causes. Do not panic excessively; seek medical confirmation for peace of mind.

In Hong Kong, cancer remains the leading health threat, with over 30,000 new cases diagnosed annually. The most common types include lung cancer, colorectal cancer, breast cancer, nasopharyngeal carcinoma, and liver cancer, often linked to smoking, dietary habits, EBV infection, hepatitis B carrier status, or family history.

Many people, even before a formal cancer diagnosis, notice in the early stages: “Why do my clothes suddenly feel looser lately?”
Weight drops inexplicably by 1–2 kg or more, often causing confusion and worry.
This is not “successful weight loss” or “stress eating less” — it is cancer beginning to “steal” the body’s nutrition and energy right from the early phase.

After a cancer diagnosis, the one question that weighs most heavily on patients and families is always the same: “Will recurrence come sooner than expected?”
Traditional follow-up methods, while reliable, often leave people in a state of “passive waiting” anxiety:
Tumour markers (CEA, CA19-9, CA125, etc.) are prone to false positives due to inflammation or infection;
Imaging (CT, PET-CT) only detects tumours once they have grown to a certain size.
This means that early recurrence signals may already be present long before any confirmation is possible.

Let you clearly know “how your immunity is right now” — no longer just a feeling
Many cancer patients, after treatment or during long-term follow-up, most often ask:
“Has my immunity recovered yet?”
Conventional blood tests showing white blood cell or lymphocyte counts can only tell you “normal” or “low”,
but cannot reveal the overall “fighting strength” of your immune system at this moment.

In the field of modern oncology, early detection and personalized treatment have become key to improving survival rates and quality of life for patients. RGCC (Research Genetic Cancer Centre) testing is a series of advanced blood-based assays that require only a single blood draw to analyze circulating tumor cells (CTCs) and related biomarkers. These tests provide critical insights into the presence, progression, and treatment response of cancer, helping physicians create truly tailored treatment plans. The three most commonly used tests—Oncotrace, Onco-D-clare, and Onconomics Plus—excel in monitoring, screening, and treatment optimization, respectively.

RGCC OncoTrace is one of the most advanced circulating tumour cell (CTC) detection and monitoring technologies available internationally. With a single blood draw, it can capture cancer cells that have “escaped” the tumour and are circulating in the blood, providing key information on quantity, phenotype, and activity. This allows physicians to detect changes before tumour markers rise or imaging shows any alteration.

Turning “quiet worry” into a calm, actionable plan
When breast, ovarian, colorectal, pancreatic, thyroid, or multiple cancers have appeared in your family,
the question “Could it happen to me?” often lingers in the background.
The good news: hereditary cancers represent only 5–10 % of all cases — yet this small percentage is the most preventable when identified early.
