How Exemestane Works
Exemestane operates by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens. This reduction in estrogen levels can lead to several positive effects:
- Decreased Tumor Growth: By lowering estrogen, Exemestane can slow down the progression of hormone-sensitive cancers.
- Improved Survival Rates: Studies indicate that treatments with Exemestane can lead to improved survival rates for women with breast cancer.
- Reduced Risk of Recurrence: Usage of Exemestane after surgery can help lower the chances of cancer returning.
Potential Side Effects
While Exemestane can provide significant benefits, it is essential to consider potential side effects, including:
- Hot Flashes: Many women report experiencing hot flashes similar to those during menopause.
- Joint Pain: Some patients may encounter aches and discomfort in their joints.
- Fatigue: Feelings of tiredness and lethargy can occur during treatment.
Conclusion
Exemestane is a powerful tool in the fight against hormone receptor-positive breast cancer, but its effects should be carefully weighed against potential side effects. As with any medication, consulting with a healthcare provider before starting treatment is crucial for ensuring that the benefits outweigh any risks.
