 Wyatt -
I took my little cousin to the hospital today and wanted to know whether cancers can be detected via a blood test, can someone answer me about this question?
Thanks in advance.

Normal blood test do not reveal it. The doctors must do a physical examination for knowing whether there is any cancerous disease. Although for certain cancers there are tumour marker type blood test. Why are you worried about cancer?
Kind regards.
