多种癌症早期检测试验（MCED）

您的健康旅程

In order to become cancerous, a cell first experiences one or more changes in its DNA. This is the genetic information that controls how the cell behaves. Once these DNA changes have occurred, then the cell may begin to divide out of control, which causes it to become cancerous. A blood test can look for abnormal DNA fragments (also known as circulating tumor DNA or ctDNA) in the blood that are associated with cancer. This is sometimes known as a “liquid biopsy,” because it checks for cancer cells in much the same way that a biopsy does. However, instead of taking out a small piece of tissue surgically, the liquid biopsy uses a blood test. DNA fragments are released from cancer cells into the bloodstream, making it possible to detect many different types of cancer with a single blood test.
