What's LDIS?

Hi,

Does anyone know what LDIS is? My Mum had her letter today confirming her mastectomy date and her results from lumpectomy and  in the letter it says that in between her two tumours she had LDIS which shows an unstable breast. But I can’t find anywhere what LDIS is xx

I think it must be a typing error and is called LCIS… if you google you will get a definition …good luck
