Swelling after breast reconstruction surgery, including with radiation, is a common experience. Some swelling, called lymphedema, can be a long-term side effect of both radiation and surgery. This involves a buildup of lymphatic fluid in the breast, chest, or arm area.
Many people experience ongoing swelling for several months after surgery. As one MyBCTeam member shared, it took about six months post-surgery for their swelling to start decreasing. If you notice any of these concerning symptoms with your swelling, contact your doctor immediately:
• Excessive pressure
• Skin discoloration
• Hot skin
• Increased pain
• Heavy bleeding or clots
Your doctor may need to drain accumulated fluid (called a seroma) if it's causing discomfort or not resolving on its own.
