EvaMarie, I recently was diagnosed /DCIS/Ductile Carcinoma in Situ/my understsanding is in situ(sytu) means the carcinoma is incapsulated in my case---in the duct--I had a lump on my breast.The surgeon said he was preety sure it was just a fatty cyst but the pathology report came positive for DCIS.Since he removed the lump and 1cm of surrouning tissue --I was considered cured--no chemo,radiation etc.I hope this helps you .God Bless.Kathie
