**Core Concept**
Hormone replacement therapy (HRT) in post-menopausal women involves the administration of estrogen and progesterone to alleviate symptoms of menopause. The therapy can have several potential risks and benefits, making it essential to understand its implications on various aspects of a woman's health.

**Why the Correct Answer is Right**
The correct answer is related to the risks associated with HRT, which include an increased risk of breast cancer, ovarian cancer, and blood clots. Estrogen can stimulate the growth of breast cancer cells and increase the risk of developing ovarian cancer. Additionally, estrogen can also increase the risk of blood clots due to its effects on blood coagulation.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because breast cancer is a well-documented risk associated with HRT. The increased risk of breast cancer is thought to be due to the stimulation of breast tissue by estrogen.
* **Option B:** This option is incorrect because ovarian cancer is also a recognized risk of HRT. The increased risk of ovarian cancer is thought to be due to the stimulation of ovarian tissue by estrogen.
* **Option D:** This option is incorrect because thromboembolic events, including blood clots, are a known risk of HRT. The increased risk of blood clots is thought to be due to the effects of estrogen on blood coagulation.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the risks of HRT are dose-dependent and duration-dependent, meaning that the longer a woman is on HRT and the higher the dose, the greater the risk of adverse effects.

**Correct Answer: D. Thromboembolic events are not a potential risk associated with HRT.
