Liver abscess:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
In pyogenic liver abscesses, the common infecting organisms are Escherichia coli, Klebsiella, Staphylococcus, Streptococcus, Bacteroides, and enterococcus. The infecting organisms may invade the liver directly after a liver wound or they may spread from the lungs, skin, or other organs by the hepatic artery, portal vein, or biliary tract. Pyogenic abscesses are generally multiple and commonly follow cholecystitis, peritonitis, pneumonia, and bacterial endocarditis.
An amebic abscess results from infection with the protozoa Entamoeba histolytica, the organism that causes amebic dysentery. Amebic liver abscesses usually occur singly, in the right lobe.
There are 8 to 16 cases of liver abscess for every 100,000 people hospitalized, and there is a 5% to 30% mortality rate. Most cases occur in people in their 60s and 70s.

Liver cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The immediate cause of liver cancer is unknown, but it may be a congenital disease in children. Adult liver cancer may result from environmental exposure to carcinogens, such as the chemical compound aflatoxin (a mold that grows on rice and peanuts), thorium dioxide (a contrast medium formerly used in liver radiography), Senecio alkaloids, and possibly androgens and oral estrogens.
Roughly 30% to 70% of patients with hepatomas also have cirrhosis. (Hepatomas are 40 times more likely to develop in a cirrhotic liver than in a normal one.)
Whether cirrhosis is a premalignant state or alcohol and malnutrition predispose the liver to develop hepatomas is still unclear. Other risk factors are exposure to the hepatitis C virus and the hepatitis B virus.
Liver cancer accounts for roughly 1% of all cancers in the United States and for 10% to 50% in Africa and parts of Asia. Liver cancer is most prevalent in men (particularly men older than age 60), and incidence increases with age. It's rapidly fatal, usually within 6 months, from GI hemorrhage, progressive cachexia, hepatic failure, or metastasis.

About prevalence and incidence statistics:
The term 'prevalence' of Liver conditions usually refers to the estimated population
of people who are managing Liver conditions at any given time.
The term 'incidence' of Liver conditions refers to the annual diagnosis rate,
or the number of new cases of Liver conditions diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
