Nastrosa tablets 1mg Why do I need this medicine? Anastrozole is used to treat breast cancer in women who have reached menopause (menstrual cycle has stopped).
Anastrozole lowers the level of a female hormone called oestrogen. This helps to slow down the growth of breast cancer cells because breast cancer cells need oestrogen to grow.
It can be used on its own or together with chemotherapy, radiotherapy or surgery to treat breast cancer.
Anastrozole may also be used for other purposes, such as to prevent breast cancer in women who are at a high risk of developing breast cancer.

Your doctor may also perform a bone mineral density (BMD) test to determine the condition of your bones before starting you on Anastrozole.
