BCR and cancer: If the malignant tumor were to be ablated via surgery or other techniques, the stimulation of neutrophils and suppression of lymphocytes would be relieved, and circulating neutrophils and lymphocytes would be restored back to normal or strengthened to some extent, which also leads to decreased inflammatory carcinogenic factors, strengthened immune surveillance of circulating tumor cells or other minimal malignant lesions and better BCR‐free survival.
