Abstract
The organization of radiotherapy and oncology in Sweden is described, from the first small pioneer roentgen institutes, via the early Radiumhemmet and King Gustaf V's Jubilee Clinics, up to the present organization with its regional coordinating oncologic centres and Department of oncology and radiotherapy at the regional hospitals, as well as at some large central county hospitals. The great importance of Gosta Forssell's early organizing work and foresight for this development is underlined.
