Hi there, I've noticed an indentation in my left breast. Noticeable when I lean forward. The indentation is towards to top part of my breast. Also the skin near to my left armpit is also slightly swollen and there is a pulling feeling around the area. I've an appointment with my GP on Monday. I'm 55. I'm not sure whether it is just lack of elasticity of skin due to my age but it's only visible on the left breast.  I've noticed other women's comments that their indentations are always on the bottom of the breast which is different to mine. Not quite sure what it is but my left breast definitely doesn't feel right.
