Recognizing Liver Cancer Awareness Month in October: Are You at Risk?

Liver cancer is a serious but often preventable disease with early detection and lifestyle modifications. More than 800,000 people are diagnosed with liver cancer throughout the world each year, and it is the 6th most common cancer. Liver Cancer Awareness Month is observed each October to raise awareness about the risks, symptoms, and treatments for liver cancer, a disease that affects millions of people worldwide. The goal is to educate the public about liver health and the importance of early detection in improving outcomes.

One of the leading risk factors for liver cancer is nonalcoholic fatty liver disease (NAFLD), a condition affecting over 100 million people in the U.S. alone. NAFLD, along with its more severe form, nonalcoholic steatohepatitis (NASH), can cause liver damage that may progress to hepatocellular carcinoma (HCC), the most common type of liver cancer. As awareness increases, so does the hope for early detection, timely treatment, and improved survival rates.

Types of Primary Liver Cancer in Adults

Liver cancer can be classified into several types, but the two most common primary liver cancers in adults are hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC is the most prevalent form of liver cancer, often developing in individuals with chronic liver diseases like cirrhosis or hepatitis. HCC accounts for about 85-90% of all liver cancer cases. Also known as bile duct cancer, cholangiocarcinoma affects the bile ducts inside or outside the liver. It is less common but still a significant form of liver cancer. Both types of liver cancer are serious and often related to underlying conditions such as viral hepatitis (hepatitis B and C), alcohol use, or NAFLD/NASH. Early detection is key to improving treatment outcomes for both HCC and cholangiocarcinoma.

Are You at Risk?

Several risk factors increase the likelihood of developing liver cancer, many of which are related to lifestyle and liver health, including diagnosis of chronic liver diseases. Key risk factors include:

  • Nonalcoholic Fatty Liver Disease (NAFLD): This condition occurs when fat builds up in the liver, even in people who drink little to no alcohol. It is often associated with obesity, type 2 diabetes, and metabolic syndrome.
  • Nonalcoholic Steatohepatitis (NASH): A more severe form of NAFLD, NASH involves liver inflammation and scarring, increasing the risk of liver cancer.
  • Viral Hepatitis: Chronic infection with hepatitis B or C can lead to cirrhosis, a significant risk factor for liver cancer.
  • Heavy Alcohol Consumption: Long-term excessive drinking can cause cirrhosis and significantly increase liver cancer risk.
  • Cirrhosis: This scarring of the liver tissue, often caused by chronic liver disease, greatly increases the risk of developing HCC.
  • Type 2 Diabetes: People with type 2 diabetes are at higher risk of NAFLD, NASH, and subsequently liver cancer, due to liver fat accumulation and insulin resistance.

By identifying risk factors early, individuals can work with healthcare providers to mitigate these risks through lifestyle changes and regular monitoring of liver health.

Common Symptoms of Liver Cancer

Liver cancer symptoms often go unnoticed until the disease is in an advanced stage, which is why early detection is essential. Some of the most common symptoms of liver cancer include sudden or unintentional weight loss, persistent pain or bloating in the upper abdomen, jaundice or yellowing of the skin and eyes, chronic fatigue or weakness, and loss of appetite or feeling full quickly.

If you are experiencing any of these symptoms, it is essential to talk to a healthcare provider and undergo the appropriate screening tests, such as a liver ultrasound or Fibroscan, which can help assess liver stiffness and scarring.

Treatments for Liver Cancer

The treatment options for liver cancer depend on the type, size, location, and stage of the tumor, as well as the patient’s overall health. Common treatments include:

  • Surgery: In cases where the tumor is localized, surgery to remove part of the liver (a liver resection) may be an option. In more advanced cases, a liver transplant may be required.
  • Ablation Therapy: This method uses extreme heat or cold to destroy cancer cells and is often used for small tumors.
  • Radiation Therapy: High-energy rays are used to target and destroy cancer cells. Radiation therapy may be used when surgery is not an option.
  • Chemotherapy: Chemotherapy uses powerful medicines to kill fast-growing cancer cells.
  • Targeted Therapy: Unlike conventional chemotherapy, which affects both cancerous and healthy cells, targeted therapy focuses on the specific molecules involved in tumor growth.
  • Immunotherapy: This treatment boosts the body’s immune system to help fight the cancer cells and is an emerging treatment option for liver cancer.

The earlier liver cancer is detected, the more treatment options are available, underscoring the importance of regular liver health check-ups and screening.

When to Talk to Your Doctor

If you have risk factors for liver cancer – such as a history of NAFLD, NASH, viral hepatitis, or chronic alcohol use – regular monitoring of liver health is critical. Early detection of liver damage can significantly improve outcomes. If you experience symptoms such as persistent abdominal pain, jaundice, or unexplained weight loss, it’s important to seek medical advice in a timely manner.

During Liver Cancer Awareness Month, healthcare providers and organizations spread awareness and focus on supporting research to find better treatments and potential cures for these conditions. By raising awareness and funding research, we can improve the lives of people with liver cancer and individuals at risk of developing liver cancer.
