Breast cancer classification
Different classification techniques can be used to group breast cancers. Each of these classification systems has a distinct goal and uses various criteria to categorise tumours. Organizing classes based on pathology: The cancer is categorised based on its microanatomy and cellular structure. This is the most typical way to categorise or type breast cancer.

Classification according to grade: The pathologist assigns a grade to cancer. For instance, a low-grade tumour that has undergone "well-differentiation" mimics healthy tissue. Poorly differentiated tumours, also known as high-grade tumours, are made up of disordered cells and do not resemble normal tissue. Some are also in the intermediate grade or are "moderately differentiated." Cancer stage-based classification: TNM staging, which considers the tumour size, lymph no...
