ADVANTAGES OF HORMONAL THERAPY:
The biggest advantage of hormone therapy is that it significantly decreases your chances of the breast cancer occurring again.
The treatment is systemic, and affects cancer cells all over your body, not just in one specific area.
DISADVANTAGES OF HORMONAL THERAPY:
Depending on several factors, this type of treatment can cause infertility, hot flashes, vaginal dryness, and other symptoms of menopause.
These symptoms can continue for as long as you are taking the drugs, which will probably be for five years. Hormonal therapy also slightly increases your risk of uterine cancer and blood clots.
