1. Effective in treating estrogen receptor-positive breast cancer: Aromasin has been shown to be effective in treating estrogen receptor-positive breast cancer in postmenopausal women. It helps to reduce the levels of estrogen in the body, which can slow down or halt the growth of certain types of breast cancer cells.
2. May reduce the risk of breast cancer recurrence: Aromasin, when used as part of adjuvant therapy, may help reduce the risk of breast cancer recurrence in postmenopausal women who have undergone surgery for early-stage breast cancer. It may also be used as part of extended adjuvant therapy for up to 5 years to further reduce the risk of recurrence.

Cons:

1. Requires a prescription: Aromasin is a prescription medication and can only be obtained with a valid prescription from a qualified healthcare provider. This means that it cannot be used without proper medical supervision and is not intended for unauthorized use.
2. Potential for side effects: Like any medication, Aromasin has the potential for side effects, although they are generally mild and well-tolerated. Common side effects may include hot flashes, fatigue, joint pain, and increased sweating. In rare cases, more serious side effects such as bone loss, osteoporosis, and fractures may occur, and regular monitoring may be needed.
