Appearance of oval cells in the liver of rats after long‐term exposure to ethanol
P G Smith, L B Tee, G C Yeoh – 1 January 1996 – Epidemiological studies show an increased risk of developing liver cancer among alcoholics. There is some agreement that ethanol itself is not carcinogenic, but it may enhance the tumorigenic process by inducing drug‐metabolizing enzymes, suppression of the immune system or by affecting DNA repair enzymes. Precisely how ethanol predisposes or promotes the development of hepatoma is unknown.
