Preinv-2	Therapeutic concept for preinvasive lesions
	An individualized treatment strategy should be elaborated for and offered to every patient with ductal carcinoma in situ (DCIS) without invasive portions. The patient must be briefed on the arguments for and against the particular therapies and combinations of these therapies, as well as on the advantages with respect to the likelihood of local recurrence and the absence of an effect on the probability of survival.
