How can liver cirrhosis and liver cancer be differenciated???

Cirrhotic at risk. liver cancer usually happens in a cirrhotic liver. cirrhosis = scarring of the liver, cancer = uncontrolled cell growth. if you really have cirrhosis, you need to be screened for cancer regularly (can happen in 1-3% of cirrhotics per year)
Usually. Primary liver cancer (hepatocellular carcinoma, or HCC) can usually be seen on modern ct scan, or PET-ct scan. It is usually seen as a separate mass within a nodular, shrunken liver if cirrhosis is present. Definitive diagnosis is usually made with a biopsy of the tissue, often done by an interventional radiologist. No scan however is perfect. Hope this helps.

What are the causes of liver cirrhosis and liver cancer?

Multiple. The most common causes of liver cancer are cirrhosis and hepatitis b. Cirrhosis can be caused by any type of hepatitis (alcoholic, infectious, autoimmune, iron storage diseases, non-alcoholic fatty liver, e tc). Read more...
Etoh, hepatitis, etc. Alcohol and hepatitis c are the most common causes of cirrhosis in the us. Worldwide, hepatitis b is #1 etiology. Other causes include toxins, heart failure, inflammatory autoimmune diseases, or unknown causes in about 30% of cases (idiopathic).

How does cirrhosis cause liver cancer? I have liver cirrhosis, and i’ve read that increases my risk of getting liver cancer. How does that work?

Cell . Cell growth and death is always occurring all over our body, including liver cells. Cirrhosis results in disrupted anatomy of the cells of the liver. Over time this affects dna. Alterations in dna can result in mutations of genes that make liver cells. When mutations occur there is a risk of a mutation involved in cell programming, to include programmed cell death, which is supposed to occur. When the genes that program the liver cell to die fail to work, the cell can multiply/grow out of control, which is what cancer is. This growth requires a lot of energy and nutrients, supplied by blood. In time, this growth overtakes the body's ability to compensate for the increase in nutrient requirements and death ensues.

Nobody knows fully. Cirrhosis is both a degenerative and an inflammatory disease. The nodules of abnormal liver tissue are growing abnormally because they are inflamed by whatever caused the cirrhosis (hep viruses, alcohol, auto immune disorder etc.). Chronic inflammation can lead to malignant transformation, and does in 10%+ of cases of long-term cirrhosis. Reducing the inflammation, when possible, is what helps. Read more...

Is it possible to diagnose liver cirrhosis or liver cancer without a biopsy?

Yes and no. No need to have a liver biopsy to diagnose liver cirrhosis. Sono of liver or MRI liver will be able to tell you if you have liver cirrhosis. Not all liver cancer requires biopsy to establish a diagnosis. A very high level of Alpha feto protein-and evidence of liver mass which c/w primary liver cancer- are enough to make a diagnosis. If AFP is low or if suspicious for metastasis- biopsy is needed. Read more...
Yes and no. Cirrhosis is a histologic diagnosis but can made without a biopsy with almost certainty based on lab data, imaging studies and physical exam. Liver cancer (hcc) is also a histologic diagnosis, but in the setting of cirrhosis it can be made based on MRI or ct imaging criteria without a biopsy with >95% certainty. Read more...

My sister just got diagnosed with liver cirrhosis from years of drinking and abusing prescription medication. Does it ALWAYS lead to liver cancer?

No. cirrhosis can be caused by many situations and alcoholic hepatitis leading to cirrhosis is not uncommon. this can be a fatal situation. she needs to follow her physician orders. she will benefit from a rehab so that she can stop drinking and drugging. continued drinking alcohol and cirrhosis is a fatal combination. immediately stop using/drinking and needs help now to help her stop. Read more...
No. Usually it doesn't. However, if she does not stop drinking, it is just as deadly as if it was cancer. You already know that there is nothing you can do to change her. I am glad you are there for her should she be able to get her life together and seek you out. Best wishes. Read more...
Not always. Hepatocellular cancer, liver cancer, is greatly increased with patients with cirrhosis. Cirrhosis is associated with hepatocellular cancer in 80 % of the cases. In the United States, cirrhosis is the 12th leading cause of death. Abstinence of alcohol, Tylenol (acetaminophen) and other drugs that harm the liver are essential. The diagnosis is usually confirmed by a biopsy of the liver. Good luck , God speed. Read more...
