. Primary liver cancer is cancer that forms in the tissues of the liver. On the other hand, secondary liver cancer occurs when cancer starts in another part of the body but spreads to the liver. Secondary liver cancers are also called liver metastases or metastatic liver cancer. This is different from having cancer that first started in the liver (primary liver cancer). In primary liver cancer, the cancer consists of liver cells (hepatocytes) that have become cancerous. This distinction is important because the type (origin) of your cancer tells your doctor what kind of treatment you need. So, for example, cancer that starts in the colon (intestine) can spread to the liver and is called colon (intestine) cancer and spreads to the liver, not hepatocellular carcinoma. Cancer cells in the liver are the same type of cells that originated in the colon (intestine) and are treated as colon (intestinal) cancer.

Most liver cancers are secondary liver cancer or metastatic liver cancer. And any cancer can spread to the liver.
Understanding Liver Cancer 了解肝癌
Primary liver cancer, which begins in the liver, accounts for about 2% of cancers in the United States, but up to half of all cancers in some developing countries.
. This is largely due to the prevalence of hepatitis B and hepatitis C viral infections, which predispose a person to developing liver cancer.
. In the United States, primary liver cancer affects twice as many men as women, with an average age of 67 years. The incidence in men is 11.5 per 100,000 compared with 3.9 per 100,000 women.
Several types of cancer can form in the liver. The most common type of liver cancer is hepatocellular carcinoma (HCC), which begins in the main type of liver cell (hepatocytes). Other types of liver cancer, such as intrahepatic cholangiocarcinoma and hepatoblastoma, are less common.
Early Signs Of Liver Cancer: Learn To Diagnose
Your liver is the largest organ within your body. You cannot live without a liver because the liver helps your body digest food, store energy, and eliminate toxins.
His liver is located below his right ribs, just below his right lung. Your liver is divided into lobes.
A large right lobe, a smaller left lobe, and two small lobes, the quadrate lobe and the caudate lobe (Fig. 2). Each lobe is separated into many small liver lobules, which are the functional units of the liver (Fig. 3).
The liver is made up mainly of cells called hepatocytes. It is also made up of other types of cells, including cells that line blood vessels and cells that line the small tubes in the liver called bile ducts. The bile ducts extend outside of the liver and carry bile from the liver to the gallbladder or directly to the intestines.

Different types of cells in the liver can form various types of malignant (cancerous) and benign (non-cancerous) tumors. These tumors have different causes, are treated differently, and have a different prognosis.

The American Cancer Society estimates for primary liver cancer and intrahepatic bile duct cancer in the United States for 2022 are
The incidence of liver cancer has more than tripled since 1980. However, rates of liver cancer have recently begun to decline. Liver cancer death rates have increased by about 3% per year since 2000. Liver cancer occurs more often in men than in women.

Liver cancer is more common in sub-Saharan African and Southeast Asian countries than in the United States.
. In many of these countries, liver cancer is the most common type of cancer. More than 700,000 people are diagnosed with liver cancer each year worldwide. Liver cancer is also one of the leading causes of cancer death worldwide, causing more than 600,000 deaths each year.
It is often difficult to detect liver cancer at an early stage because signs and symptoms often do not appear until it is in its late stages. Small liver tumors are difficult to detect on physical examination because most of the liver is covered by the right rib cage. By the time the lump is felt, it may already be quite large.
There are no widely recommended screening tests for liver cancer in people who are not at increased risk. (Screening is a test for cancer in people who do not have any symptoms.) But the test may be recommended for some people at higher risk.
Benign Liver Tumors: Video, Anatomy & Definition
Many patients who develop liver cancer have long-term cirrhosis (the formation of scar tissue from damage to liver cells). Doctors may test for liver cancer if a person with cirrhosis gets worse for no apparent reason.
For people who are at high risk of developing liver cancer because they have cirrhosis (of any cause), hereditary hemochromatosis, or chronic hepatitis C infection (even without cirrhosis), some experts recommend liver cancer screening with alpha-fetoprotein tests ( TO). . PB) and ultrasound every 6 months. Ultrasound uses sound waves to take pictures of internal organs. In some studies, screening has been linked to better survival from liver cancer.
Alpha-fetoprotein (AFP) is a protein that can be measured in the blood of patients with liver cancer. But looking for high levels of alpha fetoprotein (AFP) isn’t a perfect test for liver cancer. Many patients with early liver cancer have normal AFP levels. Also, alpha-fetoprotein (AFP) levels can be increased due to other types of cancer, as well as some non-cancerous conditions.
At this time, the American Cancer Society does not have recommendations for liver cancer screening in people at intermediate risk.

. Screening means testing for cancer in people who do not have symptoms or a history of cancer. But the test may be recommended for some people at higher risk.
Cancer that begins in the liver is called primary liver cancer. The liver is made up of different types of cells.
The type of liver cancer you have depends on where it starts and what type of cell it starts in. Knowing what type of liver cancer you have helps your doctors decide what treatment you need. The different types of primary liver cancer are:
If the cancer started elsewhere and then spread to the liver, it is called secondary liver cancer or metastatic liver cancer (see Secondary liver cancer section below).
Liver Tumor Complicated By Bleeding
Hepatocellular carcinoma, also called hepatocellular carcinoma or hepatocellular carcinoma, is the most common type of primary liver cancer in adults with approximately 90 percent of liver cancers in the United States.
Hepatocellular carcinoma develops from the main liver cells called hepatocytes. It is more common in people with chronic liver disease such as cirrhosis. Cirrhosis means scarring of the liver due to previous damage. For example, damage caused by the hepatitis B or hepatitis C virus, or long-term alcohol use.
Men are more likely to develop hepatocellular carcinoma than women. It becomes more common as you get older.
Anything that increases the risk of developing a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; Not having risk factors does not mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor.
Liver Cancer Cells Manipulate Stromal Cells I
. Hepatocellular carcinoma is closely related to chronic infection with the hepatitis B and C viruses (HBV and HCV).
. Chronic hepatitis infection with other associated risk factors, including hepatitis D (HDV) coinfection, alcohol use, and smoking, may increase the risk of liver cancer.
. Patients with chronic hepatitis from any cause (eg, hemochromatosis, alpha-1 antitrypsin deficiency) or cryptogenic cirrhosis are at increased risk of developing hepatocellular carcinoma. Environmental exposure to aflatoxins and water contaminated with toxin from blue-green algae and betel nut contribute to hepatocellular carcinoma. Ethanol abuse and metabolic syndrome have been linked to liver cancer with persistent liver damage leading to steatosis, steatohepatitis, cirrhosis, and eventually hepatocellular carcinoma. Protective factors against hepatocellular carcinoma have been associated with statins and coffee. Treatment of chronic hepatitis, metabolic syndrome, iron removal, and cessation of alcohol use to prevent the development of cirrhosis may reduce the progression of hepatocellular carcinoma. Vaccination against hepatitis B and screening for hepatitis C virus (HCV) can reduce the incidence of HCC worldwide. HCC surveillance guidelines for high-risk populations are indicated and vary by community/institution and generally recommend including ultrasound, with or without alpha-fetoprotein (AFP), every 6 to 12 months.
Using a microscope, doctors can distinguish between various subtypes of hepatocellular carcinoma. In most cases, these subtypes do not affect treatment or prognosis. But it is important to recognize one of these subspecies, which is the fibrous laminate. This type is rare and accounts for less than 1% of hepatocellular carcinomas.
Carcinoid Syndrome: Symptoms, Treatment & What It Is
. Fibroblastoma tends to develop in people between the ages of 20 and 30, and occurs most often in women under the age of 35. The rest of the liver is often not injured.
. Fibrocystic skin cancer is usually not associated with cirrhosis or hepatitis B or C infection. Some people with other types of liver cancer may have high levels of a chemical called alpha-fetoprotein (AFP) in their blood. This is usually not the case for people with fibrolamellar carcinoma. Fibrolamellar carcinomas generally have a better outlook (prognosis) than other
