“Global liver cancer rates are expected to jump 75% by 2050, but experts say more than 60% of liver cancers are preventable. Decreases in obesity and reduced alcohol use could drive down rates of liver cancer.”

Here’s a summary of the 09/15/2025 UCHealth article Liver disease and liver cancer are on the rise. Are they preventable?

Key points

  1. Rising rates globally
    Liver cancer is projected to increase by ~75% worldwide by 2050.

  2. Large portion preventable
    Experts estimate that over 60% of liver cancer cases could be prevented.

  3. Major causes
    Globally:
    • Hepatitis B & C still play a big role in liver cancer (~37% combined), especially in developing countries.
    • Alcohol-related liver damage accounts for about 19%.
    • Obesity-related liver disease (often via fatty liver disease) contributes roughly 8%.

  4. U.S. / Colorado situation
    • Hepatitis B vaccination and cures for Hepatitis C have reduced those risks in the U.S.
    • The bigger drivers in the U.S./Colorado are alcohol-related liver disease and obesity-related liver disease (called MASLD – metabolic dysfunction-associated steatotic liver disease).

  5. MASLD / MASH explained
    • MASLD = metabolic dysfunction-associated steatotic liver disease (formerly “nonalcoholic fatty liver disease, NAFLD”). It’s fat accumulating in the liver, often tied to being overweight/obese, diabetes, etc.
    • If MASLD is associated with inflammation, it can progress to MASH (metabolic dysfunction-associated steatohepatitis), which increases risk of fibrosis, cirrhosis, and ultimately liver cancer.
    • A fairly large share of people (estimates vary) have MASLD; fewer develop MASH; fewer of those develop cirrhosis; and among those, a significant minority get liver cancer within years.

  6. Prevention / treatment
    • Lifestyle changes (weight loss, healthier diet, limiting alcohol, managing blood sugar/diabetes) are key for slowing down or reversing MASLD before it becomes more severe.
    • There are now some FDA-approved medications for MASH as of 2024: for example, resmetirom and the weight-loss drug WEGOVY (semaglutide), which help reduce liver fat and scarring.
    • Screening is important: tests for liver enzymes, imaging (ultrasound), and in some cases ultrasound elastography or biopsy. For people with cirrhosis, regular imaging (every six months) to detect tumors early is recommended.

  7. Takeaway
    Having liver disease (particularly before cirrhosis) is a major risk factor for liver cancer. So prevention of liver disease is effectively prevention of a lot of potential future liver cancers. Given that many risk factors are modifiable (diet, weight, alcohol, diabetes management), there is good opportunity to reduce incidence.
