Hard unmovable lump in breast

I found a hard pea-sized unmovable lump in my left breast about 1 inch from my nipple.  I found it about a month and a half ago.  It has not changed and I have no pain. The skin over it is slightly darkened (meaning you wouldn't notice it unless you were looking for it) and if I stretch the skin the lump is visible.  My paternal grandmother,81, was diagnosed with Stage 3 breast cancer 2 months ago.  My maternal grandmother had her leg amputated about 12 years ago due to cancer in her foot.  My maternal grandfather died from complications due to prostate cancer.  
Just over two years ago I found that I had a softball-sized tumor attached to my ovary after being taken to the ER with terrible abdominal pain (I thought it was a ruptured cyst).  I had the tumor removed--it was benign.  It was a very traumatic experience and I have not been back to the doctor since.  
I have also moved since then and do not have a regular doc or gyno here.  
I know that I should go and have the lump checked out, but I fall into a full-on panic attack everytime I even think about trying to get an appointment.  Should I be worried about the lump? I find myself obsessing over it, but I can't get over my fear of visiting a doctor.

Go to the doctor; read the article I wrote above!  If you can't get into a doctor go to Urgent Care.  It's probably nothing, but it's not worth ignoring.

Good luck

It is now, my mission  let every woman I can know, to take any lump in the breast very serious at any age! . I understand your anxiety and panic attacks. I use to always think it was better to not know than to know. I now think this type of thinking is not good and will only cause more anxiety and fear. The knowing is the only way we can be assured of nothing serious going on. Make an appointment as soon as possible. The anxiety will be relieved in knowing that you had it checked out.  Just do it! I will pray that you have a peace of mind and that your fears are relived and you are given the strength and wisdom in order for you to do this. You have to do it! Please!.
