**Core Concept**
The treatment of carcinoma cervix often involves a combination of radiation therapy and surgery. Radiation therapy is typically delivered in fractions, with the goal of minimizing toxicity to surrounding tissues while maximizing the dose to the tumor. The dose and fractionation schedule can vary depending on the stage and histology of the cancer.

**Why the Correct Answer is Right**
The correct answer, **6000 cGy**, is the typical dose delivered to Point B in the treatment of carcinoma cervix. Point B is a reference point in the pelvis that is used to plan radiation therapy. The dose of 6000 cGy is delivered in 30 fractions over 6 weeks, using a combination of external beam radiation therapy (EBRT) and brachytherapy. This dose is sufficient to control microscopic disease and reduce the risk of recurrence, while minimizing the risk of toxicity to surrounding tissues.

**Why Each Wrong Option is Incorrect**
**Option A:** 7000 cGy is too high and increases the risk of severe toxicity to the bladder, rectum, and small bowel.
**Option C:** 5000 cGy is too low and may not be sufficient to control microscopic disease, increasing the risk of recurrence.
**Option D:** 10,000 cGy is excessive and can cause fatal toxicity to the small bowel, bladder, and rectum.

**Clinical Pearl / High-Yield Fact**
The dose of radiation therapy for carcinoma cervix is typically escalated for more advanced stages of disease, but must be balanced against the risk of severe toxicity. The use of brachytherapy, such as high-dose rate (HDR) or low-dose rate (LDR) brachytherapy, can help to deliver a higher dose to the tumor while minimizing the risk of toxicity.
