2. Changes shape and size of the breast
Another sign of breast cancer is changing in the shape and size of the affected breast. In the beginning stages of cancer, the changes may be subtle and unnoticeable, so many women may not realize that they have breast cancer until the change in the shape and size become noticeable. Additionally, women’s breast naturally differs in shape and size; that is, they aren’t symmetrical.
One breast – typically the breast on the same side of the dominant arm – tends to be larger than the other, which can also make it difficult for women to spot any abnormalities in the early stages of the disease. As mentioned, breast cancer is highly treatable if it is caught early and more serious in advanced stages, so it is important for women to pay attention to their breasts and be aware of any changes in their appearance.
