First I agree with what has been said so far, but please let me add more to it since I'm an expert at this. No, I'm not a doctor, but both my Mom and I have experienced this.
Back in the very early 80's my Mom chose to have her breast tissue removed and replaced with silicone breasts because she had fibrocystic breasts. My Dad said she couldn't stand the pain anymore. Her doctor recommended silicone breasts so that she would never experience it again. In July 2002 she passed away at the age of 59. They only found cancer in her liver. They didn't have time to figure out where it came from or why. During all of those years, as far as I know, she never had them checked for leakage. That was my conclusion. My point in mentioning this is not directed at you, but to all women...DO NOT LET A DOCTOR TELL YOU THAT YOUR ONLY ANSWER IS TO REMOVE THE BREAST TISSUE TO GET RID OF FIBROCYSTIC BREAST. There is an easy solution and the doctor will not tell you, but I know the answer!
First, before I tell you, go ahead and get it checked out, but let me mention what's going to most likely happen just from my personal experience with this same problem that my Mom pasted down to me. First they will give you a mammography. Then they will say since they aren't sure, they will move you over to the sonogram room. Then they will say it's just a cyst. From this point it'll be up to you to have it drained or not. Having it drained plus another doctor bill is the fastest way to deal with the problem. You'll have huge relief in seconds. But now how can you totally avoid this expensive mess?
As mentioned before, caffine is the number one reason for a cyst. If you keep it down to one to two cups of coffee/glass of coke per week, you shouldn't have this problem. If you drink more than that, a cyst might appear. Now, how can I avoid cysts coming up at all? The answer is...
1MG OF FOLIC ACID PER DAY
Yes, that's it...that's the magic pill. How do I know this? By telling my previous OBGYN that I was seriously thinking about having children, the doctor prescribed 1mg of folic acid per day. He said it was to get me ready so to speak. Well, the first thing that I noticed was that within days all of my cysts started shrinking and eventually disappearing. Then the next thing that I noticed was that they didn't appear during my menstrual cycle. For the first time in years I was cyst free and for one whole year! After one year as the doctor was renewing my prescription, I told him about my huge discovery. I was so excited! But after I told him, he looked at me funny and totally blew me off. I couldn't believe it! I had the answer and he didn't want to share. Well, duh I should have have known. Anything to keep you out of the office is something that they aren't willing to share. There's no telling how much money I've spent on doctors and machines telling me what I have when I could have taken care of it myself for just pennies per day.
So again, go have yourself checked just in case, but from here on out, reduce your caffine intake and increase your folic acid to at least a minimum of 800mcg per day. I have found that 400mcg just isn't enough for me.
Sorry if this was long winded, but I think all women should be aware of the benefits that a higher dosage of folic acid can bring especially to women who have fibrocystic breasts.
