LIVER TUMORS ABOUT THE CONDITION
The liver is the second largest organ in your body. It helps your body digest food and absorb nutrients. The liver produces bile, a substance your body needs to absorb vitamins.
Equally important, the liver filters drugs, alcohol, chemicals, and environmental toxins from your blood. It can filter up to 1 1/2 quarts of blood each day. Its role as a blood filter makes the liver susceptible to secondary (metastatic) tumors. These are tumors whose cells have spread to the liver through the bloodstream from other parts of the body.

5. Superior mesenteric artery
Primary liver tumors originate in the liver. The most common form is hepatocellular carcinoma (HCC).1 HCC can start as a single tumor in the liver. It then grows and spreads to other parts of the liver. HCC can also start as many small tumors throughout the liver. When HCC is found only in the liver, it’s called “localized.” HCC can spread outside the liver to the lymph nodes or to other organs in the body. The most common risk factors for HCC are hepatitis B, hepatitis C, cirrhosis, nonalcoholic fatty liver disease, or exposure to aflatoxins.1
Secondary (or metastatic) liver tumors originate in another part of the body and spread to the liver. In most cases, the metastatic liver tumor grows from cells that have spread from cancers in the colon or rectum.2
If you visit your doctor when you first notice symptoms, your liver tumor(s) might be diagnosed earlier, when intervention is most likely to help.3 Symptoms do not necessarily mean you have a tumor. However, most liver tumor patients experience symptoms such as these:
Liver tumors can cause other symptoms too. These include fever, enlarged veins on the belly that can be seen through the skin, and abnormal bruising or bleeding.
