A 42-year-old woman from rural Maharashtra presents with postcoital bleeding and vaginal discharge for 3 months. On examination, a friable cervical mass is noted. Pap smear shows high-grade squamous intraepithelial lesion (HSIL). Colposcopy-directed biopsy confirms squamous cell carcinoma. MRI pelvis shows a 4 cm cervical lesion with parametrial invasion but no distant metastases. Pelvic lymph nodes are not enlarged on imaging. What is the FIGO 2009 stage of this cervical cancer?
