A 41-year-old woman is diagnosed with CA Cervix. She has right hydronephrosis as evidenced by the intravenous pyelogram (IVP). The biopsy specimen confirms it is squamous cell cancer. Which of the following statements regarding this patient’s condition is most accurate?

**Core Concept**
The patient has squamous cell carcinoma (SCC) of the cervix, which has caused right hydronephrosis due to its local extension and potential involvement of the ureters. This condition highlights the importance of understanding the anatomical relationships and potential complications of cervical cancer.

**Why the Correct Answer is Right**
Squamous cell carcinoma of the cervix is a type of epithelial cancer that arises from the squamous cells of the cervix. In advanced stages, SCC can invade and extend to surrounding structures, including the ureters, leading to hydronephrosis. The correct answer highlights the common site of metastasis and spread of cervical cancer.

**Why Each Wrong Option is Incorrect**
**Option A:** While lymph node metastasis is a common mode of spread for cervical cancer, it is not the most accurate statement regarding hydronephrosis.
**Option B:** The correct answer is not related to the histological type of the primary tumor, but rather its potential to cause hydronephrosis through local extension.
**Option C:** The correct answer is not related to the involvement of the bladder, which is not directly implicated in the pathogenesis of hydronephrosis in this case.

**Clinical Pearl / High-Yield Fact**
Cervical cancer can cause hydronephrosis through direct invasion of the ureters, which is a critical consideration in the management of advanced cervical cancer.

**Correct Answer:** C.
