The increasing incidence of testicular cancer in East Anglia.

We have studied the age-related incidence of testicular cancer in the East Anglian region. The incidence for both teratoma and seminoma has almost doubled since 1960. Teratoma incidence, stable from 1960-1969 at 0.9 per 10(5) of the male population, increased between 1970 and 1975 to 1.7. This rise was the result of increased occurrence among younger men. Seminoma incidence also rose from 1.5 to 2.5 per 10(5), most rapidly between 1975 and 1980. Causes for the rising incidences have been suggested.
