Which indicators in blood routine can detect cancer

Abnormal indicators in blood routine may indicate cancer risk, mainly including abnormally high white blood cell count, sustained decrease in hemoglobin, and significant increase or decrease in platelets. These indicators need to be comprehensively judged based on clinical symptoms and other examinations. Common associated indicators include absolute neutrophil count, red blood cell distribution width, average red blood cell volume, etc.

1. White blood cell abnormalities: Blood system tumors such as leukemia often lead to a significant increase in white blood cell count, and abnormal absolute neutrophil values may indicate bone marrow proliferative diseases. When some solid tumors metastasize to bone marrow, they may cause leukemoid reaction, which shows that the white blood cell count exceeds 20 × 10 ⁹⁹/L. infectious diseases can also cause white blood cell elevation, which needs to be identified by bone marrow puncture and other examinations.

2. Decreased hemoglobin:
