Hi,
I have a pain in my left breast for over 2 weeks. I have only checked my breast when I was breastfeeting, and normal, there were lumps. When the the pain didn’t go, I have checked them and there was a lump where the pain was stronger. In the summer I had a chest pain that I thought that was my harț, but now, I think it was my breast. Today I found another one, near my arm,but I am on my period, and I don’t know if It is normal to have lumps, only at one breast, in this period of the month. I will have a scan on the 3thd of december. Should I worry?
