Hello! In case of Moderately Differentiated Invasive Squamous Cell Carcinoma, the treatment options are Radiotherapy, Immunotherapy and Surgery. Given the fact that your mother is 59 years old, you can disregard immunotherapy as a treatment option. But still a proper quotation can only be made after deterministic tests like - MRI of the pelvis and CECT (Contrast Enhanced Computed Tomography) Scan. Hope my answer helps you.
