Dr. Jin Zhongkui
A CA19-9 level reaching 300 may be caused by pancreatic cancer or bile duct cancer. Additionally, other malignant tumors can also lead to CA19-9 levels exceeding 300. When CA19-9 levels rise above 300, further diagnostic tests are recommended to confirm the underlying cause before initiating treatment.
