Brief summary (registry, in English)
The objective of this observational study is to evaluate the false positive rate of the blood test based on molecular biomarkers and risk factors. A total of 250 patients diagnosed with various cancers and gastrointestinal diseases will be enrolled. The main question to be answered is Does the blood test have a low false positive rate in the main study population? Participants will donate a blood sample as part of their regular medical care for cancer diagnosis and give the consent to know their clinical risk factors.
