551 patients were diagnosed with breast cancer in Tampere University H
ospital district, Finland between 1977 and 1980. The number of follow-
up visits during the first 5 years was 8248. The biological, physical,
mental and social dimensions of breast cancer were measured by death,
recurrence of disease, Karnofsky score, physical or mental symptoms,
and sick leave. The prevalence rates of an event and the incidence rat
es of the appearance or disappearance of an event were used to determi
ne the indicators for these different dimensions of breast cancer. The
study was based on hospital case notes. Data on death, recurrence, si
ck leave and Karnofsky score were well recorded, but physical or menta
l symptoms were recorded infrequently. There was a 4-fold difference b
etween the highest and lowest prevalence for the different dimensions,
but the trends were similar by follow-up time. The variation was also
large for the incidence rates but the trends differed with length of
follow-up time. The biological, physical, mental and social consequenc
es of breast cancer differ in magnitude and have different trends over
time, indicating that breast cancer is a different disease depending
on the dimension and on the indicator under consideration.
