Which stage of cervical cancer involves the uterus but not the pelvic walls?

In the context of cervical cancer staging, Stage 2 is defined by the involvement of the cervix and the uterus, while not having spread to the pelvic walls or lower third of the vagina, which differentiates it from more advanced stages. Specifically, Stage 2 cervical cancer includes cases where the cancer has extended beyond the cervix to the uterus, but there is no infiltration into surrounding structures or organs, such as the pelvic walls.

This stage indicates that the cancer is still relatively contained and has not progressed to more severe states where it impacts either the pelvic walls (as seen in Stage 3) or distant sites (as seen in Stage 4). Thus, understanding the specific definitions of each stage helps in determining the accurate progression of the disease, specifically noting that by Stage 2, the cancer’s reach does not encompass the pelvic walls, which is crucial in correct classification and subsequent treatment approach.
