Seven tumor markers

The seven normal tumor markers refer to carbohydrate antigen 125, carbohydrate antigen 153, alpha-fetoprotein, carcinoembryonic antigen and carbohydrate antigen 242, carbohydrate antigen 199 and neuron-specific enolase. Different tumor markers represent different tumor types. For patients, when showing tumor, they may show an increase in tumor markers. For the increase in tumor markers, it is recommended that patients go to local regular hospitals for more detailed examination to determine whether it is caused by malignant tumor.
