liver cancer

Liver cancer, a disease where malignant cells form in the tissues of the liver, presents unique challenges. Early detection through screening and awareness of risk factors are crucial. Treatment options vary depending on the stage and overall health, ranging from surgery and liver transplantation to targeted therapies and immunotherapy. Learn more about liver cancer, its diagnosis, and the latest treatment approaches.Understanding Liver CancerWhat is Liver Cancer?Liver cancer occurs when cells in the liver grow uncontrollably, forming a tumor. The liver, the largest internal organ, is essential for many bodily functions, including filtering blood, producing bile, and storing energy. There are two main types of liver cancer: Hepatocellular carcinoma (HCC): This is the most common type, originating in the main type of liver cell, the hepatocyte. Cholangiocarcinoma (bile duct cancer): This type begins in the bile ducts within the liver.Sometimes, cancer that starts elsewhere in the body can spread (metastasize) to the liver. This is called metastatic liver cancer and is different from primary liver cancer.Risk Factors for Liver CancerSeveral factors can increase the risk of developing liver cancer: Chronic Hepatitis B or C infection: Long-term infection with these viruses is a major risk factor. Cirrhosis: Scarring of the liver from any cause (e.g., alcohol abuse, fatty liver disease) significantly increases risk. Alcohol Abuse: Excessive alcohol consumption damages the liver and increases the risk of HCC. Non-alcoholic Fatty Liver Disease (NAFLD): This condition, often associated with obesity and diabetes, can lead to cirrhosis and liver cancer. Aflatoxins: Exposure to these toxins, produced by certain molds on food, can increase risk, especially in combination with hepatitis B infection. Family history: Having a family history of liver cancer may increase the risk.According to the American Cancer Society, the incidence of liver cancer has been rising in recent decades, highlighting the importance of awareness and prevention. More information can be found on their website.Diagnosing Liver CancerSymptoms of Liver CancerIn the early stages, liver cancer may not cause any noticeable symptoms. As the tumor grows, symptoms may include: Abdominal pain or swelling Weight loss without trying Loss of appetite Nausea and vomiting Jaundice (yellowing of the skin and eyes) Weakness or fatigue Enlarged liver or spleenIf you experience any of these symptoms, it's essential to consult a doctor for evaluation.Diagnostic TestsSeveral tests are used to diagnose liver cancer: Blood Tests: Liver function tests and alpha-fetoprotein (AFP) levels can provide clues about liver health and potential cancer. Imaging Tests: Ultrasound: Uses sound waves to create images of the liver. CT Scan: Provides detailed cross-sectional images of the liver. MRI: Uses magnetic fields and radio waves to create detailed images. Liver Biopsy: A small tissue sample is taken from the liver and examined under a microscope to confirm the diagnosis and determine the type of cancer.The choice of diagnostic tests depends on individual factors and the suspected stage of the disease. Early diagnosis is crucial for effective treatment. At Shandong Baofa Cancer Research Institute, we emphasize the importance of comprehensive diagnostic approaches for accurate assessment.Treating Liver CancerTreatment OptionsTreatment for liver cancer depends on several factors, including the stage of the cancer, the overall health of the patient, and their preferences. Options may include: Surgery: Resection: Removing the tumor and surrounding healthy tissue. This is an option for early-stage cancers in patients with good liver function. Liver Transplant: Replacing the diseased liver with a healthy one from a donor. This is an option for certain patients with advanced but localized cancer. Local Ablation Techniques: These techniques destroy the tumor without removing it. Radiofrequency Ablation (RFA): Uses heat to destroy cancer cells. Microwave Ablation (MWA): Similar to RFA but uses microwaves. Cryoablation: Uses extreme cold to freeze and destroy cancer cells. Embolization Therapies: These therapies block the blood supply to the tumor. Transarterial Chemoembolization (TACE): Delivers chemotherapy directly to the tumor along with substances that block blood flow. Transarterial Radioembolization (TARE) or Selective Internal Radiation Therapy (SIRT): Delivers radioactive beads directly to the tumor. Targeted Therapy: These drugs target specific molecules involved in cancer cell growth and survival. Examples include sorafenib and lenvatinib. Immunotherapy: These drugs help the body's immune system fight cancer. Examples include pembrolizumab and nivolumab. Radiation Therapy: Uses high-energy rays to kill cancer cells. This may be used for pain relief or to shrink tumors. Chemotherapy: Uses drugs to kill cancer cells. Chemotherapy is not typically used as the primary treatment for HCC but may be used in certain situations.The following table provides a comparison of different treatment options for liver cancer: Treatment Option Description Suitable For Surgery (Resection) Removal of tumor and surrounding tissue Early-stage cancer, good liver function Liver Transplant Replacement of diseased liver Advanced but localized cancer RFA Uses heat to destroy cancer cells Small tumors, not suitable for surgery TACE Delivers chemotherapy directly to tumor Intermediate-stage cancer Targeted Therapy Targets specific molecules in cancer cells Advanced cancer, certain genetic mutations Immunotherapy Helps the immune system fight cancer Advanced cancer Prevention and Early DetectionPreventing liver cancer involves addressing risk factors: Vaccination against Hepatitis B: This is a highly effective way to prevent hepatitis B infection and subsequent liver cancer. Antiviral Treatment for Hepatitis B and C: Effective antiviral treatments can reduce the risk of cirrhosis and liver cancer. Limiting Alcohol Consumption: Moderate or avoid alcohol consumption to protect the liver. Maintaining a Healthy Weight: This can help prevent NAFLD and subsequent liver damage. Screening: Regular screening for liver cancer is recommended for individuals at high risk, such as those with cirrhosis or chronic hepatitis B or C infection. Screening typically involves blood tests and ultrasound scans.The team at Shandong Baofa Cancer Research Institute is dedicated to advancing the understanding and treatment of liver cancer.
