What to expect from mastectomy for ductal carcinoma in situ

Ductal carcinoma in situ is contained within a milk duct, but its extent and location can affect the choice between breast-conserving surgery and mastectomy. Your team will explain why mastectomy is being considered and whether the nipple or skin can be preserved.

The removed tissue is examined by pathology. In some situations, the surgeon also discusses lymph-node assessment because later findings could change treatment planning. The pathology result is reviewed at follow-up.

Give the hospital a complete list of medicines and supplements, and ask when to stop or restart them. Confirm fasting instructions, transport, support at home, drain supplies, and the timing of the first wound review.

After discharge, follow instructions for bathing, dressings, pain relief, and arm movement. Keep track of drain output when requested. Rest, walk gently as advised, and avoid lifting until the surgeon says the wound is ready.

Report feverishness, spreading redness, increasing warmth, pus-like drainage, wound opening, sudden swelling, or pain that is getting worse. Seek emergency help for severe breathlessness, chest pain, fainting, or bleeding that does not stop with firm pressure.

Ask why mastectomy is recommended for your ductal carcinoma in situ, whether lymph nodes need assessment, what tissue will be removed, how reconstruction affects recovery, and how pathology will guide follow-up.
