Don't feel bad about seeing your doctor a lot, if its something serious you'll want to know sooner rather than later. When i was 15 (I'm 23 now) i noticed a large lump in my left breast which hurt and didn't move around very much. I did nothing about it out of shame...2 years later i developed another in my right breast. I seen a doctor who refered me to a surgeon. At 17 I had a double lumpectomy. Both were tumors which weren't cancerous, but its scary going through something like that. I'm glad i did though because now I know how serious breast lumps can be. Get checked out by a doctor. It could be regular tissue, a tumor, a cyst, you'll never know unless you get checked out
Get it checked. You don't want to wait IF something COULD be wrong. NOT saying anything is, but don't take a chance.
First of all.......DO NOT EVER feel badly about making your doctor do their job, particularly about something this important. It's much better to be safe than sorry.
Many women normally have regular periods of time when their breasts naturally become very lumpy, but the lumps go away pretty quickly. I am one of those women and it sounds like you might also be one. Because of this, I always had a terrible time figuring out what I was feeling when I did a self-examination of my breasts. That's very scary until you can get an educated opinion from a doctor. Actually, naturally lumpy breasts sometimes confound even the doctors. I had one doctor rush me off to see a surgeon because of the lumpiness, but fortunately it turned out to be nothing at all. Many years later, I felt something unusual about my breast. Even though "unusual" is normal for me, I went to the doctor right away to have it checked out. It turned out that I had breast cancer, but because I had it checked out by the doctor right way, it was identified at an early stage of the cancer. That was 6 years ago, and I'm still a survivor. So do self-examinations, see your doctor regularly to be checked, and don't forget to have your mammograms done. Your doctors are paid very well for their troubles, so don't ever worry about them. It's your life, after all, and you only have one!! Good luck and God bless you.
