Question

In breast cancer staging, the patient was rated N1. This means that

A. the cancer has not spread beyond the breast
B. the cancer is confined to one or two lymph nodes
C. the patient has a small tumor
D. there is no evidence of metastasis

Answer 1

N1 stage in breast cancer staging signifies that the cancer has spread to one or two nearby lymph nodes.

Step-by-step explanation:

In breast cancer staging, if a patient is rated N1, this indicates that the cancer has spread to nearby lymph nodes. Specifically, stage N1 typically describes a condition in which cancer is confined to one or two lymph nodes. This stage falls under the category of regional cancer, which defines cancer that has gone beyond its original site to nearby tissues or lymph nodes. Cancer staging is essential in determining the appropriate treatment and prognosis for the patient, as it helps to classify cancer based on factors such as the size of the tumor and the extent to which the cancer has spread.
