When a patient is diagnosed with breast cancer that has spread to the lymph nodes, surgery is a critical step. Doctors often have to decide how much of the lymph node area needs to be removed. This decision is vital because the surgery can be physically demanding, but it must also ensure that the cancer does not return in the armpit area.
Researchers looked at data from 4,670 patients who had already received certain treatments before surgery. They compared patients who had a full lymph node removal to those who did not. The results showed no clear difference in the rate of cancer returning in the armpit between the two groups. Both groups showed very low rates of recurrence, with figures staying under 6% in both cases.
While the results are encouraging, the evidence comes from non-randomized studies, which means the groups were not perfectly balanced from the start. However, the findings suggest that for certain patients, skipping the extra surgery might reduce physical complications without increasing the risk of the cancer coming back. You should talk to your doctor to see if this approach fits your specific treatment plan.
