I'm posting here in desperation as I've been trying to get an appointment at the doctors but can't get through. I first noticed this little lump on the underside of my right breast about 5 weeks ago. At first I thought it was a spot and I've been putting sudocrem on it. Sometimes it appears to have a little white head on it but I've tried squeezing it and nothing comes out. It's skin coloured and doesn't hurt at all. It's only tiny and feels like it has a hard centre. I finally plucked up the courage to go to the doctors and I can't get through. Pic attached.
