Are liver lesions dangerous by themselves, and how would they affect someone with cirrhosis?

What is a "lesion" A lesion is a non-specific and meaningless term meaning there is "something" seen in the liver that shouldn't be there. It can be very serious, or can mean little or nothing. Depends on what the lesion is - a benign tumor, a cancer, an infection, tuberculosis, a cirrhotic nodule - all are lesions. At 26, i hope you aren't speaking of yourself. Lesions need a biopsy or some specific diagnosis.
Yes. Chance of bleeding with liver lacerations, bile leaking and causing infections in abdomen - grading of liver laceration is done for categorizing the severity level, which may range from one to six. Liver laceration grade i is mild, while grade vi indicates a very serious condition.
