## **Core Concept**
The question revolves around the management of cervical cancer, specifically stage I, and the surgical procedures involved. Radical hysterectomy is a surgical procedure that involves the removal of the uterus, cervix, and part of the vagina, and is a treatment option for early-stage cervical cancer. The FIGO (International Federation of Gynecology and Obstetrics) staging system is used to classify the extent of spread of cervical cancer.

## **Why the Correct Answer is Right**
For stage I cervical cancer, where the cancer is strictly confined to the cervix, radical hysterectomy is a standard treatment. When the cancer extends to the lower part of the body of the uterus and the upper part of the cervix, the surgical approach might need adjustment but generally, additional treatments such as radiation therapy or chemotherapy might be considered based on final pathology and risk factors. However, the immediate next step after finding such an extent of cancer during surgery would typically involve ensuring complete removal of the tumor if possible and then considering adjuvant therapy.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Without specific details on what this option entails, it's hard to directly refute, but generally, any option suggesting no further treatment would be incorrect given the cancer's extension.
- **Option B:** Similarly, without specifics, one can't directly address, but typically, more information or a specific treatment plan would be needed.
- **Option C:** This option might suggest a change in treatment plan, which could be correct depending on what it entails, such as adjuvant therapy.
- **Option D:** Assuming this is the correct answer, the others are incorrect based on standard management protocols.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that for early-stage cervical cancer, surgery is often the primary treatment, but the extent of surgery and additional treatments like chemotherapy or radiation depend on the stage, patient's health, and final pathological findings. Adjuvant therapy may be recommended based on risk factors for recurrence.

## **Correct Answer:** D.
