That term I am not sure about, but for years I have what they call natural lumpy breasts. I feel lumps all over. They are sort of a cyst, but non cancerous. I've had to have a few drained which is no big deal. I started having mammograms when I was about 30, because of my "natural lumpiness" and family history. Main thing is to watch and check often. The other thing you can do, is take Vit. E (1000mg once a day), it does help keep the cysts like mine down. My doctor gets on me if he finds out I havent' been taking Vit. E.
Keep in mind, as women we are pretty lucky that breast cancer or ovarian cancer is pretty treatable. Not always successful (wouldn't want to give you false hope) but much better chance of success than any other cancer.
My mother and her sister both have had breasts removed. I've been lucky so far and have only had to have some cysts drained. If you have no family history of it, that is better yet. Check yourself and go to your doctor regularly!!!!
In fact, I am due for my mammogram now. I am almost 45.
Actually when I first started going for mammograms, they found they had to do ultrasound instead because the tissue of a woman that young doesn't show up well enough on mammogram.
Relax, until you go back, and make your doctor explain things to you!!!!!!!!
