Liver lesions are groups of abnormal cells in your liver. Your doctor may call them a mass or a tumor. Noncancerous, or benign, liver lesions are common. They don’t spread to other areas of your body and don’t usually cause any health issues. But some liver lesions form as a result of cancer.

Liver lesions are abnormal growths that may be noncancerous (benign) or cancerous. Benign lesions occur for a variety of reasons and are typically not cause for concern. Liver cancer is less common but more serious.

What causes Hyperdense lesions in the liver?

Can liver lesions shrink on their own?
