Breast cancer (all types)

aka Breast carcinoma, Carcinoma of the breast

Breast cancer is not one disease. Which of three receptor patterns the tumour carries decides its treatment: hormone receptor-positive (about 70 percent), HER2-positive (about 15 percent) or triple-negative (about 15 percent). The pages for each type hold the detail; this page holds what they share.
