3. Round shape
If the lump in your breast has a round shape, then it is more than likely a fibroadenoma as opposed to a cancerous tumor. In general, malignant tumors tend to have an irregular shape and as such, they will not have a distinct shape, but rather they will present themselves in a shape that resembles an oval or an otherwise distorted circle. Very rarely do cancerous tumors of the breast have a defined round shape.
Therefore, if you have spotted any lumps within your breasts and they are unquestionably round, then it is far more likely that the mass is a benign fibroadenoma rather than a malignant cancerous tumor. Nevertheless, you should not dismiss the mass because you believe that it has a defined shape; it’s best to check with your healthcare professional to make sure that it is, indeed non-cancerous and to receive a proper diagnosis.
