I have a lump in my left breast. I went to the doctor today and told him about it. He felt it but was unconcerned and said it could be just a cyst but wanted to get it checked out further anyway. He ordered an ultrasound on it and my appointment is next Friday. My question is why wouldn't he order a mammogram? What's the difference between a mammogram and an ultrasound for something like this? It could be b/c of my age (29) or b/c it's a newly found lump (paperwork that I read in the doctor's office said you're not permitted to do a mammogram if you're under 35 or the lump is new, so that's why I guess that). I do have breast cancer genes in my family (maternal aunt and her daughter, who is my age) though.
Does anyone have experience with this? What is the difference between the ultrasound and the mammogram?
If it matters, they also did bloodwork on me today, but I'm not sure for what purpose. I went to the doctor today in order to establish a primary care doctor so he got my full medical history and such so maybe that's what the blood work was for? Just to get everything checked out? Who knows.
