Stage 1 Cervical Cancer

Description

Centered in the female pelvis, the uterine corpus tapers inferiorly into the cervix, which projects into the superior vagina and is bounded laterally by the parametrial connective tissues. A localized cervical neoplasm is shown confined to the cervix, without extension into the uterine body superiorly, the vaginal fornices inferiorly, or the pelvic sidewall laterally. Anterior to the cervix sits the urinary bladder and posteriorly the rectum, clarifying the normal anatomic planes that remain uninvolved at stage 1 disease. FIGO stage I cervical cancer is defined by carcinoma limited to the cervix, and that boundary drives both prognosis and operative planning. For microinvasive disease (IA), depth of stromal invasion and the presence of lymphovascular space invasion determine whether cone biopsy alone is appropriate or whether nodal assessment is added; for larger lesions (IB), the relationship of tumor to the internal os, parametria, and upper vagina guides selection between radical hysterectomy with pelvic lymph node evaluation versus primary chemoradiation. Clear depiction of what is and is not invaded helps explain why bladder or rectal symptoms usually signal more advanced spread, and why clinical examination plus MRI focuses on parametrial fat planes and the vaginal cuff. Gynecologic oncology teams can use this artwork in clinic to support staging discussions after colposcopy-directed biopsy, explaining conization margins, fertility-sparing radical trachelectomy, or sentinel lymph node mapping in early cervical carcinoma. It also fits well in OB-GYN and pathology curricula, tumor board slide decks, screening and HPV education materials, and publisher content comparing stage 1 cervical cancer to stage II and beyond.
