Welcome to HealthcareMagic forum. The CAT scan showing spots may be a result of radiation
therapy because though the doctors try their best to localise the radiation around the suspected mass only but some scattered radiations do reach surronding areas and produce effects like decreased cell growth and fibrosis
. It might be due to a too early scan. If anything serious comes up, it is the moral responsibility of the doctor to let you know. Don't worry too much Everything will be alright.
