Just take things one step at a time. I have a strong history of BC in my family. Both of my grandmothers (one was a 27 year survivor) And my mother. (I lost her way to young, I was 31, she was 52) After her diagnosis I insisted they started mamos on me at 30. As others have said they would take the mammo and then I would wait for it to be read. 100% of the time they had a section they wanted to review closer as I was young and had dense breast tissue.It was always nothing. I was 40 when I went for my last mammo and went through the usual. This time when I met with the doctor she asked If I had time to stay for an US and biopsy. It was probably nothing but they wanted to make sure. I was nervous but just tried to stay calm. They gave me an appointment for two days later to review the results of the biopsy. The following day First thing in the morning I got a call from them that they needed me to come in and pick up all of my films and reports as the biopsy was positive. During the biposy they put a marker in the area of concern. I'm glad that they did that because even after I knew it was there, I felt nothing. I went to several breast surgeons and reviewed my results. None of the surgeons could feel it either but it was there on every scan, mammo, us, & MRI. We had the discussion of lumpectomy or mastectomy. My mom had a lumpectomy because she couldn't face the fact of loosing her breast. Unfortunately 9 months later it was discovered that it had metastasized into her lungs and we lost her 5 months later. Way before I was diagnosed I already had made the decision that if anything was ever found that I would to the mastectomy. Of course its alot different when you are facing the fact. After some debate I made the decision to have a bilateral mastectomy with reconstruction. I was also tested to see if I was a carrier of the BRACA mutation. It turned out that I was. So not only did I have the BMX I also had my ovaries and tubes taken out. (BRACA is a mutation that makes one a bit more suspectable for both breast and ovarian cancer. (My great aunt died from ovarian cancer). For me its been a long road but I have come out the other side and am doing well. Slammed into menopause isn't fun but its something I can (and have to) learn how to deal with. I'm very glad I went the route I did. The lab reports showed not only the initial cancer but I had at least 4 other areas of the breast that were showing DCIS (precancerous cells).
Now I'm not telling this to you to scare you but to tell you it IS scary but IF there is something its so much better to catch it now than later.
My biggest worry now is for my children. I carry the gene, my sister does not. I worry if I passed this on to them. My grandmothers were in their early 60's at diagnosis, My mom was 50, I was 40. I am terrified that my girls may have to deal with it in their 30's. (And there are many young ladies who do get diagnosed). The plus is that they are only 12 now and hopefully there will be alot more options and things available as they grow up. It was 10 years between my mom's diagnoses and mine and I can tell you what I went through and the options available to me were different then what my mom went through it.
I am coming up on my 2nd year of diagnosis and with the exception of the hot flashes, feel fine. I reconstitution done at the same time as the mastectomy and although it was a hard road, I am still here and plan on being here for along time.
Good luck and again just one step at a time.
