What's the difference between a lumpectomy and a mastectomy?
A lumpectomy removes only the tumor and a small amount of healthy tissue around it, preserving most of your breast. It's also called breast-conserving surgery. A mastectomy removes all the breast tissue from one or both breasts.
Both procedures are equally effective for treating breast cancer. Research shows similar long-term survival rates, though some recent studies suggest lumpectomy with radiation may have slightly higher survival rates for early-stage breast cancer.
The choice depends on several factors:
- Tumor size and location
- Breast size
- Number of tumors
- Whether you've had previous radiation
- Your personal preferences
Lumpectomy is typically followed by radiation therapy, while mastectomy may allow you to avoid radiation in some cases. Recovery differs between the two surgeries. Lumpectomy is usually outpatient with recovery taking 5-10 days to resume daily activities. Mastectomy takes longer - up to 4 weeks, or 8+ weeks if you have breast reconstruction.
Cancer recurrence rates are slightly different. With lumpectomy plus radiation, there's about a 5-10% chance of cancer returning in the same breast. After mastectomy, the risk is around 5%.
Side effects vary too. Mastectomy may cause more scarring, numbness, and you won't be able to produce milk. Lumpectomy often has fewer surgery-related side effects, but radiation therapy can cause skin changes, fatigue, and breast swelling.
Your care team can help you weigh these factors based on your specific situation and what matters most to you.
