Final answer:
HRT increases breast cancer death risk.
Step-by-step explanation:
The statement that HRT increases breast cancer death risk is true.
Several studies have shown a link between hormone replacement therapy (HRT) and an increased risk of breast cancer. The Women's Health Initiative (WHI) study, for example, found that women who took a combination of estrogen and progestin (a type of HRT) had a higher risk of developing breast cancer compared to those who didn't take HRT. Other studies have also reached similar conclusions.
It's important to note that this increased risk is relative rather than absolute. Not all women who take HRT will develop breast cancer, but the risk is higher compared to those who don't take HRT.
