(37 cards)
Elderly patients are more likely to have (primary liver cancer / secondary metastases).
secondary metastases from other cancers
Patients with chronic liver disease are likely to have (primary liver cancer / secondary metastases).
primary liver cancer
due to the chronic inflammation - constant replenishing of cells makes DNA errors more likely, and chronic inflammation puts cells under oxidative stress which may damage their DNA

Is it benign or malignant?
Haemangioma
How are liver lesions found?
Usually through imaging / screening for other diseases
Name four types of benign liver lesion.
Haemangioma
Focal nodular hyperplasia
Adenoma
Cysts
