For individuals at high risk of liver cancer, such as those with chronic hepatitis B or C infections, or cirrhosis, screening is crucial. The NHS recommends regular ultrasound scans and blood tests for alpha-fetoprotein (AFP) levels. These tests can help detect liver cancer at an earlier stage when treatment is more effective. It's essential for at-risk individuals to discuss their screening options with their GP, who can provide personalized advice based on individual health history and risk factors.
