The shapes of tumour regrowth curves after irradiation are the combined effects of radiation damage to the tumour and to its stromal tissue. In the adenocarcinoma 284 both effects can be differentiated and studied simultaneously after fractionated irradiation. At doses per fraction between 2 and 6 Gy the stromal tissue showed much bigger split dose recovery than the tumour.
