The first and most noticeable symptom of breast cancer is the feel of a lump in the breast.
Any secretion from the nipple other than clear mucoid secretions, or bloody, non-lactational leakage should be investigated.
In case one sees that a nipple looked like it is drawn inwards or indeed has changed shape, it becomes important to seek medical attention.
Check for redness, scaly, with an ‘orange peel ‘texture because these can be indication of breast cancer.
Local changes in the size and contour of the breast including breast enlargement and formation of inversion may be early signs of a disease.
