The most common primary benign liver tumor is known as hepatocellular adenoma (HCA). It is a rare, non-cancerous tumor that usually affects women in their 20s and 30s, and can be found in both adults and children. It is typically found in the left lobe of the liver, and can be single or multiple.
HCA is most commonly caused by the use of certain types of oral contraceptives. Other potential causes include obesity, type 2 diabetes, and the use of certain medications and supplements. It is also associated with certain genetic mutations, such as familial adenomatous polyposis (FAP).
Symptoms of HCA include abdominal pain, nausea and vomiting, jaundice, and elevated liver enzymes. If left untreated, the tumor can grow, leading to further complications such as liver failure or rupture. If a diagnosis is made, treatment typically involves removing the tumor surgically. However, in some cases, the tumor can be monitored with imaging tests such as ultrasound or CT scan.
It is important to note that HCA is not the same as hepatocellular carcinoma (HCC), which is a form of liver cancer. If you are experiencing any of the symptoms mentioned above, it is important to seek medical attention immediately in order to get an accurate diagnosis.
