7/30/15 bilateral mastectomy for DCIS. No reconstruction or implants; no adjuvant therapy needed. Tender puffiness in middle of chest, closer to unaffected side. Was wearing compression binder post-op but too uncomfortable. Surgeon's nurse says not lymphedema & try male compression vest. Is seroma symptomatic of LE? 1 SLND & 8 ALND, all negative removed from right side only. How to treat seroma/LE? Exercises/massage helpful? Male compression vest? Needle aspiration? How can they tell if it's not LE?
