I didnt noe where to put this. I seem to have a very small lump on my chest. It has been here for over three months now, and it oozes a weird white paste or goo, or something, that smells awful. I thought it might be a fat deposit or something to do with fat, since I am overweight, but I am not quite sure. It is closer to the centre of the chest, and on the left breast. Is this normal?

The white stuff or ooze I am taking about, only comes out when pressure is applied.
