7/27/2017This is a follow-up to my prior question of 7/22 in which I described a new set of calcifications discovered 3 months after a lumpectomy in which 2 mm DCIS was removed. The new site is 1.5 centimeters from the first surgical site. During the biopsy all calcifications have been removed and no biopsy clip was placed due to occlusion of needle by a pre-existing surgical clip? Pathology shows 4mm of DCIS, intermediate grade, comedo type. Radiologist confirms there are no calcifcations remaining and has suggested wire localization based on prior imaging of 4 remaining and 1 removed surgical clip and their distance from the new calcifications previously seen on mammograms. Would such an approach be reliable? Has this approach been used successfully in other cases? Given these circumstances, would surveillance be reasonable given my age of 69 and slow growth of DCIS in older women? (Prior Question 999842649)

7/28/2017While DCIS isn't life-threatening, it does require treatment to prevent the condition from becoming invasive. Comedo refers to areas of dead (necrotic) cancer cells, which build up inside the tumor. When cancer cells grow quickly, some cells donít get enough nourishment. These starved cells can die off, leaving areas of necrosis. Surgical removal of the area is a part of standard therapy. While there is the chance that no residual disease may remain, obtaining pathology is the only way to confirm the presence of DCIS.
