Breast cancer is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules supplying the ducts with milk.
Signs and symptoms[edit]
The first noticeable symptom of breast cancer is typically a lump that feels different from the rest of the breast tissue.
More than 80% of breast cancer cases are discovered when the woman feels a lump[1]. Lumps may also be found in lymph nodes located in the armpit (axilla). [1]
