Atypical hyperplasia found in intrahepatic bile ducts is not necessarily cancerous, the two are related but not equivalent.
Atypical hyperplasia found in intrahepatic bile ducts refers to some abnormalities in the proliferation of intrahepatic bile duct epithelial cells, which is also called heterogeneity, manifested by cells of different sizes, various morphologies, disorganized arrangement, polymorphism of nuclei, and increase in nuclear schizophrenia, and so on. Atypical hyperplasia can also continue to develop, if it involves the whole epithelial layer but does not break through the basement membrane, it will become carcinoma in situ, and carcinoma in situ may become invasive carcinoma when it continues to develop, so atypical hyperplasia belongs to precancerous lesions.
It should be noted that atypical hyperplasia can be seen in tumor lesions, as well as in repair and inflammation, etc. Moreover, when the disease-causing factors disappear, the atypical hyperplasia that does not involve the whole epithelium may reverse and subside, so atypical hyperplasia may not necessarily develop into cancer.
It is recommended that the patient go to the hospital and be judged by the doctor.
