• Main symptoms of breast cancer in women include a lump or swelling in the breast, chest or armpit; a change in the skin of the breast such as dimpling (which may look like orange peel) or redness; a change in the size or shape of one or both breasts; nipple discharge when not pregnant or breastfeeding; and a change in the shape or look of the nipple such as inversion or a rash.
• Breast pain by itself is not usually a symptom of breast cancer.
• See a GP if you have a lump or swelling in your breast, chest or armpit; any changes in your breasts or nipples that are not normal for you; or breast/armpit pain with a family history of breast or ovarian cancer.
• Some of these symptoms, including breast lumps, are very common and can be caused by other conditions; having symptoms does not definitely mean you have breast cancer, but it is important to get checked.
