Don’t panic if your tumor marker result is abnormal! An abnormal tumor marker reading doesn’t necessarily mean you have cancer. Tumor markers only indicate the risk of cancer—it cannot confirm a diagnosis on its own. What are tumor markers? Tumor markers are proteins or antigens produced by cancer cells or by the body in response to cancer.Common examples include alpha-fetoprotein (AFP) for liver cancer, cancer antigen 19-9 (CA19-9) for pancreatic cancer, and carcinoembryonic antigen (CEA) for colorectal cancer. Doctors check these marker levels through a simple blood...

Many people talk about doing ctDNA, which actually uses ctDNA (circulating tumor DNA) detection technology to analyze tumor DNA fragments in the blood, serving as a method for early or ultra-early cancer screening. Thus, ctDNA is no longer just a laboratory tool but has become a powerful weapon in cancer diagnosis and monitoring. This test only requires drawing a few milliliters of blood to detect traces of tumor DNA released into the bloodstream, regarded as a "liquid biopsy." In recent years, it has become increasingly recommended in private medical centers, especially suitable for regular...

There are many types of cancer screening methods available — but what exactly sets them apart? Can any test tell you with 100% certainty whether you have cancer?Let’s take a closer look at two major types of blood-based cancer screening: Cancer Marker Tests and mRNA Testing. The first helps with preliminary risk assessment, while the second focuses on ultra-early detection.They differ in principle, accuracy, and target users — and combining both can improve overall screening results. What is a cancer marker test? A cancer marker test measures the concentration of...

mRNA testing is a blood-based diagnostic technology that analyzes tumor-associated mRNA molecular markers in the bloodstream. It is used for ultra-early screening to detect whether tumor cell activity has occurred in the body. The test requires only a small amount of blood and involves no invasive procedure or radiation. Its accuracy, sensitivity, and specificity can reach approximately 93–97%. Key Features of mRNA Testing: Precise and efficient: Multi-marker analysis captures tumors as small as 0.2 cm. Safe and convenient: Zero radiation, minimal blood draw, can be done...

Many men are familiar with benign prostatic hyperplasia (BPH). But do you think it’s just about having a weak urine stream or waking up once or twice at night to urinate — something minor? What if I told you that when the condition becomes serious, it could actually lead to memory decline or even incontinence? Would that surprise you? We are honored to have Dr. Lee Huen share several serious cases of benign prostatic hyperplasia and explain important related information. As a man, you should definitely pay attention and take care of your health. If you have related symptoms or...
