Prospective Screening and Differentiating Common Cancers Using Peripheral Blood Cell-Free DNA Sequencing
Trial Parameters
Brief Summary
The goal of this observational study is to screen and differentiate common cancers in participants with or without suspicious lesions. The main question the investigators aim to answer is: Can the developed model, using peripheral blood cell-free DNA sequencing, work well in screening and classifying common cancers especially in the early stages? Participants will undergo the collection of 15\~20ml of blood and 1\~2 telephone follow-up calls.
