Dr. Peng Xiaodong
In mid-stage kidney cancer, vomiting yellow fluid may be due to severe vomiting causing the expulsion of gastric contents, resulting in the appearance of yellow vomit, which clinically refers to bile. However, obstruction of the gastrointestinal tract or improper diet within a short period cannot be ruled out as contributing factors. It is recommended that the patient undergo further examinations to determine the exact underlying cause and receive targeted treatment accordingly.
