Hi Amanda I have invasive ductile carcinoma. Believed to be in stage 2 but have not had surgery or lymph nodes biopsies yet. My breasts are on the larger side D cup and very dense tissue. I want to understand if the size and density of breast tissue has an affect on the success of radiation after lumpectomy. Are there more reoccurances in women with large dense breasts if so mastectomy may be a better option for me.
