briefly explain the pros and cons of hormone therapy

This ultimately depends on what it's being used for...

@Kennedy, you marked this solved. Mind giving us an idea what you wrote as your answer?

What Are the Pros and Cons of Hormone Replacement Therapy?

Pros:

Prevents bone loss that can lead to osteoporosis
Relieves symptoms of menopause
Lowers risk of colon cancer
Lowers risk of macular degeneration, vision loss that occurs when the macula, the part of the retina at the back of the eye that provides sharp, central vision, deteriorates with age

Cons:

While HRT may help many women get through menopause, the treatment is not risk-free. Known health risks include:

An increased risk of endometrial cancer (if a woman still has her uterus and is not taking progesterone along with estrogen)
Increased risk of blood clots
Increased risk of stroke
Increased risk of gallbladder disease
Increase in blood pressure in some women
Increased risk of larger, more invasive breast cancers (combination HRT only)
