Breast Conservation Surgery vs Mastectomy: When Each Is Appropriate
November 17, 2024
Surgical treatment of breast cancer aims at local and regional control, addressing both the breast itself and the axilla, and the first decision is whether the breast can be conserved at all.
When conservation is not an option
Breast conservation, whether a lumpectomy or a wider quadrantectomy, is ruled out when the disease is widespread within the breast, or when surgical attempts repeatedly leave a positive margin. A relative factor is the ratio of tumor size to breast size: conservation should only be offered when it can leave a cosmetically acceptable breast, and removing more than half the breast to conserve it defeats the purpose.
Mastectomy, and why patients sometimes choose it anyway
Where conservation is contraindicated, mastectomy follows, which can be total, modified radical, skin-sparing, or, increasingly, robotic. Beyond the medical indications, patient preference is itself a legitimate factor: many Indian patients specifically prefer removal of the breast over conservation, and that preference is treated as a valid indication for mastectomy in its own right.

FROM THE LIVE Q&A

Is there a correlation between certain cosmetics, such as talc or lipstick, and the development of breast cancer?
Dr. Jalaj Baxi
Various myths and misconceptions exist around this, including the use of talc in the axilla. Some print media point to possible links, but there is no confirmatory or corroborative evidence for a connection between cosmetics and breast cancer.
Frequently Asked Questions
A 65-year-old woman has metastatic breast cancer and mastectomy is not feasible; she is currently on chemotherapy. What chemotherapy regimens are appropriate?▼
The regimen depends on the tumor's biology, specifically its ER, PR, and HER2 status. Treatment is usually a combination approach built around anthracycline-based chemotherapy along with hormonal therapy where relevant, and HER2-targeted therapy is added when HER2 is positive. A typical course runs six to eight cycles, though HER2-directed therapy in HER2-positive disease can extend to around 18 to 20 cycles.
Can chemotherapy be combined with hormonal therapy, and what other management plans and success rates apply in metastatic disease?▼
Yes, combining chemotherapy with hormonal therapy is possible. Further management depends on how the patient responds to treatment. Roughly 30 to 35% of metastatic breast cancer patients respond well, and where the response is strong enough, it can become possible to address the metastatic sites and the primary tumor surgically as well.
If a patient remains symptomatic after eight cycles of chemotherapy, what other treatment options are available?▼
Immunotherapy can be added, and second-line or third-line chemotherapy regimens are available, including CDK4/6 inhibitors. Next-generation sequencing of the tumor helps identify which newer targeted drugs are likely to be effective for that specific patient.
Why do many patients' health seem to deteriorate immediately after a breast cancer diagnosis?▼
This is largely psychological rather than driven by the disease itself, a kind of cancer phobia that sets in once the diagnosis is given, where the patient loses a sense of control over their own life and fears dying early or being treated inadequately. Educating patients about their specific disease and realistic treatment outcomes helps restore the sense that there is still a fight to be had, which improves how they cope.
In what situations is prophylactic mastectomy appropriate in early-stage breast cancer?▼
Only in patients with a genetically determined risk, specifically those who test positive for BRCA1 or BRCA2 mutations. BRCA testing itself is only done when there is a family history of breast cancer.
What rules out breast conservation surgery?▼
Widespread disease within the breast and a persistently positive margin despite repeated surgical attempts are the two major contraindications. A poor ratio of tumor size to breast size is a related, relative contraindication, since conservation should only leave a cosmetically acceptable result.
Is mastectomy only performed when conservation is medically ruled out?▼
No. Patient preference is itself considered a valid indication for mastectomy, and many patients choose it even when conservation would be medically feasible.
