(57) [Summary] [Structure] LF in normal exocrine gland cells or tissues or in secretory fluid secreted from the cells or tissues. The presence or absence of tumor cells is determined by determining the presence or absence of A-1. This makes it possible to diagnose cancer. [Effect] For this method, a gastric biopsy specimen, hair root, sweat, or other sample can be used, and cancer can be easily diagnosed. |
