What is Liver Cancer?
Liver cancer is a type of cancer that begins in the cells of the liver. It occurs when abnormal cells in the liver grow out of control and form a tumor. Liver cancer is also known as hepatic cancer and can be either primary (starting in the liver) or secondary (spreading to the liver from another part of the body).
Primary liver cancer is the sixth most common cancer worldwide and the second leading cause of cancer-related deaths. Most cases of primary liver cancer occur in individuals with chronic liver disease, such as cirrhosis, hepatitis B, or hepatitis C. Secondary liver cancer is more common than primary liver cancer and is often the result of cancer that has spread from the colon, pancreas, stomach, or breast.
Causes of Liver Cancer
The exact cause of liver cancer is unknown, but several risk factors have been identified, including:
- Chronic liver disease, such as cirrhosis
- Hepatitis B or C virus infection
- Excessive alcohol consumption
- Obesity
- Diabetes
- Aflatoxin exposure (a toxin produced by a type of fungus that can contaminate certain foods, such as peanuts and corn)
- Fatty liver disease
- Genetic factors
It’s important to note that having one or more of these risk factors does not necessarily mean that an individual will develop liver cancer. However, individuals with these risk factors should be aware of their increased risk and take steps to reduce their chance of developing the disease.
Risk Factors for Liver Cancer
Liver cancer is a serious condition that can develop in anyone, but certain factors can increase the likelihood of developing the disease. Understanding the risk factors is important for early detection and prevention.
Chronic Hepatitis
Chronic hepatitis is a condition characterized by long-term inflammation of the liver. This condition can lead to liver cancer. Hepatitis B and C are the most common causes of chronic hepatitis. People with chronic hepatitis are at a higher risk of developing liver cancer.
Cirrhosis
Cirrhosis is a condition in which the liver tissues are replaced by scar tissue. This condition can lead to liver cancer. Alcoholism and chronic hepatitis are the most common causes of cirrhosis. People with cirrhosis are at a higher risk of developing liver cancer.
Exposure to Toxins
Exposure to certain toxins such as aflatoxins or vinyl chloride can damage the liver and lead to liver cancer. Aflatoxins are produced by a fungus that grows on food products, such as peanuts and corn. Vinyl chloride is a chemical used in the production of plastics.
Obesity
Obesity is a significant risk factor for liver cancer, especially in men. Obesity can cause fatty liver disease, which can lead to cirrhosis and liver cancer.
Diabetes
Diabetes is another risk factor for liver cancer. People with diabetes are more likely to develop fatty liver disease, which can lead to cirrhosis and liver cancer.
Family History
Family history of liver cancer or any liver disease can increase the risk of developing liver cancer.
If you have any of these risk factors, it is important to talk to your doctor about getting screened for liver cancer. Early detection is key to successful treatment.
Symptoms of Liver Cancer
Liver cancer often does not show symptoms in the early stages, which can make it difficult to diagnose. However, as the cancer progresses, the following symptoms may arise:
- Loss of appetite and weight loss
- Feeling full after a small meal
- Nausea and vomiting
- Swollen belly and stomach pain
- Fatigue and weakness
- Yellowing of the skin and eyes (jaundice)
- Itchy skin
- Darker urine
- Pale stools
- Enlarged liver or spleen
- Unusual bleeding or bruising
When to See a Doctor
If you experience any of the above symptoms, it’s important to see a doctor right away. However, keep in mind that these symptoms may also be caused by other conditions. Only a doctor can determine the cause of your symptoms.
Stages of Liver Cancer
Liver cancer is classified into different stages based on the size of the tumor and whether it has spread to other parts of the body. The stages of liver cancer are generally determined through diagnostic tests, such as imaging scans and biopsies.
Stage 1
In this stage, a single tumor is present in the liver and has not spread to nearby blood vessels or lymph nodes. The tumor is typically smaller than two inches in size.
Stage 2
In stage 2, either a single tumor larger than two inches or multiple small tumors are present in the liver. However, the cancer has still not spread to nearby blood vessels or lymph nodes.
Stage 3
Stage 3 liver cancer has advanced locally and has spread to nearby blood vessels or lymph nodes. There may be one or more tumors present in the liver, and they may be of varying sizes.
Stage 4
At this stage, the cancer has spread to other organs beyond the liver, such as the lungs or bones. Also known as metastatic liver cancer, stage 4 is the most advanced stage of liver cancer.
The stage of liver cancer affects treatment options and chances of recovery. If you or a loved one has been diagnosed with liver cancer, it’s important to discuss treatment options with a healthcare professional.
Diagnosing Liver Cancer
Diagnosing liver cancer typically involves a combination of physical examinations, imaging tests, and blood tests. If a healthcare provider suspects liver cancer based on symptoms or risk factors, they may perform a blood test to check for an elevated level of alpha-fetoprotein (AFP), a protein that can be a sign of liver cancer.
Imaging tests, such as an ultrasound, CT scan, or MRI, may also be used to identify abnormalities and help diagnose liver cancer. If these tests show a possible malignancy, a biopsy may be recommended to confirm the diagnosis. During a biopsy, a small piece of liver tissue is taken for analysis under a microscope to determine if cancer cells are present.
In certain cases, additional diagnostic tests may be necessary to determine the extent of the cancer’s spread in the liver and other parts of the body. These tests may include a PET scan, bone scan, or endoscopy.
Treatment Options for Liver Cancer
The treatment options for liver cancer depend on the stage of the cancer, the patient’s overall health, and other factors. Some common treatment options for liver cancer include:
- Surgery: Surgery is often the first treatment option for liver cancer. The surgeon may remove part of the liver (a liver resection) or the entire liver (a liver transplant).
- Chemotherapy: Chemotherapy uses drugs to destroy cancer cells. It may be given orally or intravenously.
- Targeted Therapy: Targeted therapy drugs target specific genes or proteins, blocking the growth and spread of cancer cells.
- Immunotherapy: Immunotherapy stimulates the body’s immune system to attack cancer cells.
- Radiation therapy: Radiation therapy uses high-energy radiation beams to kill cancer cells.
- Ablation Therapy: Ablation therapy destroys cancer cells by applying heat or cold to the tumor.
- Embolization: Embolization is a minimally invasive procedure that blocks the blood supply to the cancer cells, causing them to shrink and die.
Surgery for Liver Cancer
Surgery is often the most effective treatment option for liver cancer if the tumor has not spread outside the liver. The surgeon may remove part of the liver or the entire liver, depending on the location and size of the tumor.
If the entire liver is removed, a liver transplant may be necessary. The patient will need to take immunosuppressant drugs after the surgery to prevent the body from rejecting the new liver.
Chemotherapy for Liver Cancer
Chemotherapy uses drugs to kill cancer cells. It may be given orally or intravenously. The drugs travel through the bloodstream and attack the cancer cells throughout the body. Chemotherapy may be used to shrink the tumor before surgery or to destroy remaining cancer cells after surgery.
Chemotherapy may cause side effects such as nausea, vomiting, fatigue, hair loss, and a weakened immune system. Patients should discuss the potential side effects of chemotherapy with their doctor.
Radiation therapy for Liver Cancer
Radiation therapy uses high-energy radiation beams to kill cancer cells. It may be used alone or in combination with chemotherapy. Radiation therapy may also be used to relieve symptoms such as pain or discomfort.
Radiation therapy may cause side effects such as fatigue, skin irritation, nausea, and diarrhea. Patients should discuss the potential side effects of radiation therapy with their doctor.
Targeted Therapy for Liver Cancer
Targeted therapy drugs target specific genes or proteins that are involved in the growth and spread of cancer cells. These drugs may be given orally or intravenously, and they have fewer side effects than chemotherapy.
Common targeted therapy drugs for liver cancer include sorafenib and lenvatinib. These drugs may cause side effects such as diarrhea, fatigue, and high blood pressure.
Immunotherapy for Liver Cancer
Immunotherapy stimulates the body’s immune system to attack cancer cells. This may involve the use of drugs or other substances that boost immune system function.
Common immunotherapy drugs for liver cancer include nivolumab and pembrolizumab. These drugs may cause side effects such as fatigue, skin rash, and diarrhea.
Ablation Therapy for Liver Cancer
Ablation therapy uses heat or cold to destroy cancer cells. This may involve the use of radio waves, microwave energy, or cryotherapy (freezing the tumor).
Ablation therapy is often used for small tumors that cannot be removed by surgery. It may cause side effects such as pain, bleeding, and infection.
Embolization for Liver Cancer
Embolization is a minimally invasive procedure that blocks the blood supply to the cancer cells. The doctor may insert a small tube (catheter) through a vein in the groin and thread it up to the liver. The doctor then injects tiny beads or a special gel into the artery that supplies blood to the tumor, causing it to shrink and die.
Embolization may cause side effects such as pain, fever, and nausea. Patients should discuss the potential side effects of embolization with their doctor.
Managing Liver Cancer Symptoms
Living with liver cancer can be challenging, but there are strategies you can use to manage your symptoms and improve your quality of life. Here are some suggestions:
- Eat a healthy diet: A balanced diet can help you maintain your strength and energy levels. Try to eat plenty of fruits, vegetables, whole grains, and lean proteins.
- Stay active: Regular exercise can help you maintain your strength and reduce fatigue. Talk to your doctor about what types of physical activity are safe for you.
