These are the breast cancer symptoms which aren't lumps to look out for.
Breast cancer is when abnormal cells in the breast begin to grow and divide in an uncontrolled way and eventually form a growth (tumour). It starts in the breast tissue, most commonly in the cells that line the milk ducts of the breast.
According to Cancer Research UK, it is the most common cancer in the UK and mainly affects women, but men can get it too. Breast Cancer Awareness also runs the whole month of October where charity Breast Cancer Now raises awareness of checking for symptoms and abnormalities.
