The incidence of liver cancer appears lower in Europe and the USA and
it is often looked upon as a problem in developing countries. Liver ca
ncer has two main risk factors: the abuse of alcohol and the elevated
prevalence of hepatitis B and C viruses. In Italy the first one is mai
nly present in the North and the second one in Southern less developed
areas. Our study evaluate the relationship between living in urban an
d suburban zones in South of Italy in conditions of overcrowding, poor
health services and high incidence of hepatitis and liver cancer.
