This book happened because I was worried and bewil-<br >dered about changes in my own breasts. As I talked to<br >other women， I found that many of them shared my<br >concerns~and that few of them were getting the<br >answers they needed.<br > I was fortunate enough to discover the Breast<br >Health Center at Children s Hospital of San Fran-<br >cisco. They helped me， and then agreed to collaborate<br >on a book to share their information and practical<br >counsel with women everywhere.<br > This book is not about breast cancer. It s about all<br >the breast changes that aren t breast cancer， from the<br >most innocent general lumpiness through breast car-<br >cinoma in situ (noninvasive breast carcinoma)~a<br >topic of special interest to the breast team at Chil-<br >dren s Hospital. (Doctors still disagree on whether<br >breast carcinoma in situ is properly classified as the<br >last stage in a continuum of benign breast changes or<br >as an early cancer.)<br > My thanks go to the members (current and for-<br >mer) of the breast health team at Children s Hospital:<br >Cathy Coleman， R.N.， nurse specialist; Patricia T.<br >Kelly， Ph.D.， medical geneticist; Michael D.
