Summary

This trial is testing how well turkey tail mushroom works in treating post-menopausal women with a specific type of breast cancer. Previous evidence suggests that taking turkey tail mushroom can shrink tumors before surgery. Researchers

Who is the study for?
This trial is for post-menopausal women with a specific breast cancer type: HER2-negative and ER-positive. They should be scheduled for surgery to treat their cancer. The eligibility criteria are not fully listed, but typically include factors like general health status and no conflicting conditions.
What is being tested?
The trial is testing the effects of Turkey Tail Mushroom (TTM) extract on shrinking tumors in patients before they undergo surgery. It's based on traditional uses and some evidence suggesting it might help reduce tumor size within two months prior to surgical intervention.
What are the potential side effects?
While the side effects of TTM are not detailed here, common reactions may include digestive discomfort or allergic responses, given its natural origin and use in traditional medicine.
