本期简介
Every cell that dies in your body releases DNA fragments into the blood — this is cell-free DNA (cfDNA). Cancer cells add their own methylation marks to it. This episode explains what methylation is, why it is an 'early and tissue-specific' signal, and how laboratories read these marks — with relatable examples.
This background prepares the ground for understanding methylation-based tests such as Galleri® and OverC®.

Rx-only——凭处方的筛查检测. Galleri® 不是诊断检测。阳性结果不代表癌症诊断；阴性结果不排除癌症。该检测不能替代医生推荐的常规癌症筛查。 Galleri® 不能检测所有癌症类型。
