Final answer:

Step-by-step explanation:
Estrogen replacement therapy (ERT) or hormone replacement therapy (HRT) can have both positive and negative effects. Some positive effects include protection from colon cancer, osteoporosis, heart disease, macular degeneration, and possibly depression. However, there are negative side effects to consider, such as an increased risk of stroke or heart attack, blood clots, breast cancer, ovarian cancer, endometrial cancer, gall bladder disease, and possibly dementia. It is important for patients to weigh the potential benefits and risks of ERT or HRT in consultation with their healthcare provider.
