What is Exemestane?
Exemestane, sold under the brand name Aromasin, is a medication used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering the amount of estrogen produced by the body. Estrogen can promote the growth of certain types of breast cancer cells, so by reducing its levels, exemestane helps to slow or stop the growth of these tumors.
How Does Exemestane Work?
Aromatase is an enzyme that plays a key role in the production of estrogen in the body. Exemestane works by inhibiting this enzyme, thereby decreasing the amount of estrogen circulating in the bloodstream. This reduction in estrogen levels can help to prevent the growth and spread of estrogen-sensitive breast cancer cells.
Exemestane Effects on Breast Cancer
Exemestane is primarily used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. The medication is typically prescribed after surgery, radiation, or other treatments have been attempted. Some of the effects of exemestane on breast cancer include:
– **Reduction in Tumor Size:** Exemestane can help shrink tumors and prevent the growth of new cancer cells.
– **Prevention of Recurrence:** By lowering estrogen levels, exemestane can reduce the risk of cancer coming back after treatment.
– **Improved Survival Rates:** Studies have shown that exemestane can improve overall survival rates in women with breast cancer.
Side Effects of Exemestane
Like all medications, exemestane can cause side effects. Common side effects of exemestane may include:
– Hot flashes
– Fatigue
– Joint pain
– Headache
– Nausea
– Insomnia
In some cases, exemestane can also lead to more serious side effects, such as:
– Bone fractures
– Osteoporosis
– Increased cholesterol levels
– Liver problems
It is important to discuss any potential side effects with your healthcare provider before starting treatment with exemestane.
Exemestane and Hormone Replacement Therapy
Exemestane is not recommended for use in premenopausal women or those who are pregnant. It is also not suitable for use in combination with hormone replacement therapy (HRT), as this can counteract the effects of the medication. If you are currently taking HRT or have concerns about your hormone levels, be sure to discuss this with your doctor.

Conclusion
Exemestane is a valuable medication in the treatment of breast cancer, particularly in postmenopausal women with hormone-receptor-positive tumors. By inhibiting the production of estrogen, exemestane can help to slow or stop the growth of cancer cells, ultimately improving outcomes for patients. While the medication may cause side effects, these can often be managed with proper medical supervision. If you have been prescribed exemestane, be sure to discuss any questions or concerns with your healthcare provider to ensure safe and effective treatment.
