Study on chemical exposure and breast cancer

This study looks at how chemicals in the environment (called endocrine disruptors) might affect the natural bacteria in your gut and whether that could play a role in colorectal cancer. If you are having a colonoscopy (endoscopy), you may be able to participate.

This study looks at breast cancer samples taken by biopsy to see how tissue “molecular markers” relate to how you respond to therapy and how the cancer behaves. It may help researchers better match future treatments to the biology of your tumor.

This study looks at substances in your blood (metabolites) to see if they are linked to breast cancer risk, how well treatment works, and long-term outcomes. It has three groups: women without breast cancer, newly diagnosed patients getting standard therapy, and those who have finished treatment.

This study looks at tiny particles released by cells (called extracellular vesicles) in people with breast cancer. It may help researchers better understand breast cancer and how it behaves, which could improve future testing or treatments.

This study looks at how bacteria in your gut might relate to breast cancer. By comparing tissue samples from your tumor and nearby healthy tissue, researchers hope to find new ways to understand or treat breast cancer.

This study looks at proteins and imaging patterns (from tissue, fluid near the tumor, and blood) to better understand breast cancer markers. It may help researchers find clues that doctors can use to evaluate breast nodules and newly diagnosed invasive breast cancer.
