Breast cancer screening methods start with manual palpation to check for lumps. Second, mammography is used, which is the most effective method for early diagnosis of breast cancer with a sensitivity of 80%-90%. Additionally, breast ultrasound and B-ultrasound examinations can be performed, which are simple, safe, and non-invasive. Another available method is breast MRI, which provides more accurate differentiation between benign and malignant tumors. Lastly, a biopsy using a hollow needle can also be done.
