Yes, my sister inlaw just had a lump in her breast, but it was real hard and it turned out it was just a cyst.
I have 2 lumps in my left breast just like those you mentioned. Doc told me to have a biopsy,which I had today. Waiting for the results! Fingers crossed till Monday!
I had a friend just last month have 2 lumps removed that were benign. She was scared too. The doctor called it cycstic fiborocis(not sure on spelling) but it is from to much caffiene in-take. I also had found a lump in my breast 2 1/2 yrs ago and went to the doctor they sent me for sonogram and it was a milk glan. They said I might be pregnant took a test at the doctors office and I was. I didnt even know because I had not even missed my period yet. I dont know if this is what you might have but at least you know there is other things besides cancer. I would call your doctor again and just ask him to recheck.
Hope this helps! Go luck with every thing.
