Why are axillary lymph nodes often removed during breast cancer surgery?

• A. In removing the breast, the blood supply to the nodes is removed and they will inevitably cease to function.
• B. The axillary lymph nodes receive lymph from the breast and may contain cancer cells.
• C. The nerves that supply the axillary lymph nodes are often cut during the breast surgery.
• D. It is impossible to remove the breast without physically damaging the lymph nodes.

Answer: (B)

The correct choice highlights the crucial role of axillary lymph nodes in breast cancer treatment. During breast cancer surgery, axillary lymph nodes are often removed because they play a significant role in lymphatic drainage from the breast. These nodes filter lymph fluid and serve as a pathway for cancer cells to spread beyond the primary tumor. If cancer cells are present in these nodes, it indicates a higher risk of metastasis and can influence further treatment decisions, such as the need for chemotherapy or radiation. By examining these nodes, surgeons and oncologists can assess the stage of cancer more accurately, which is essential for determining the most effective treatment plan. This procedure helps ensure that any potential spread of cancer is addressed. Therefore, the rationale for removing the axillary lymph nodes hinges on their function in cancer spread and the critical information they provide regarding the disease's progression.
