Hi! I am a thirty four year old female who has been experiencing breast pain in my left breast, for a couple of months. So, I went to the doctor and he found a lump,in the lower quadrant. It is halfway between the armpit and the nipple. It is the size of the width of your finger. I have been checking my breast and couldn't and cannot feel the lump. I am scheduled for an ultrasound. I didn't go to the doctor sooner because my breast stay tender and I am a twenty-one day cycler. So, they seem to get back sore as soon as the pain is relieved. I am terrified that I may have waited too long. The doctor's assistant said that it was a good sign because it helps when I take Ibuprofen. I also take vitamin E, do they really help and what does it mean if they do help? If this is not breast cancer, then what could it be? Also, can you tell me more about IBC? Every now and then, my nipple will itch or seem to tingle, should I be worried about this? Please help! I am terrified.
