Battle with breast lumps, anyone else?

I have a family history of breast cancer (aunt with bilateral at a very early age) and have been battling with breast lumps for the past 15 years but very frequently over the last five years or so.  My last breast mass excision was about three years ago after a horrible scare but thankfully it, as well as the others, have been benign.  Three weeks ago I had a horrible attack of cholecystitis (very abrupt) and underwent a cholecystectomy.  While showering three days ago I found yet another breast mass, this one, like the others is not painful but this one, unlike the others, is very large and on the inside of the breast near the nipple.  I feel like I am a bit OCD when it comes to checking my breasts but this mass has come on rather suddenly.  I am due for my six month mammogram in July (last one was abnormal with a mass in the OPPOSITE breast), my daughter is getting married in a few weeks and unlike the previous masses where I run off in fear to the doctor's office, I am going to wait this one out until I have my mammogram in July and then have it taken care of.  I have not told anyone in my family about it because, again, my daughter is getting married, this is such a joyous time for us all and the sudden cholecystectomy was bad enough. 

Does anyone else out there battle with breast lumps and the fear that you experience when you find them?  I have had so many removed that I am of the thinking now that eventually breast cancer will be found, even though I know how ridiculous it sounds.  I feel like there is a clock ticking down somewhere and that it is just a matter of time. 

Has anyone ever had a breast reduction for chronic breast masses?  I have researched and some say that a breast reduction (I am a 44-DD natural) will decrease the possibility of breast cancer by 50% or more and some say that it is not quite that much. 

Sorry that this is so long, was hoping to find someone with the same experiences.  :)
