Fast and Accurate Breast Cancer Diagnosis Using Nanopore Sequencing in Tanzania (Fast-ABCD Sequencing)

This study in Tanzania is testing whether a rapid genetic sequencing technology (nanopore sequencing) can quickly and accurately diagnose breast cancer from tumor tissue samples. Access to fast, reliable cancer diagnosis is a major challenge in low- and middle-income countries, and this study aims to validate a new approach that may be faster than standard methods. **You may be eligible if...** - You are suspected of having breast cancer and are undergoing a biopsy or surgery at the participating hospital - There is excess fresh tumor tissue available for testing - You can provide written informed consent **You may NOT be eligible if...** - You are unable to give informed consent - You have already started cancer treatment (conventional/biomedical treatment — herbal treatments are acceptable) Talk to your doctor to see if this trial is right for you.
