M.B.
I see my primary care provider (family doc) for everything.......
He does the pap, sends me out for mammograms, whatever. When necessary, he refers me to a specialist. (I did see an ob/gyn when I was considering what to do about the fibroids, though... but chose an alternative to a hysterectomy.) This last annual, when my mammogram came up suspicious, he referred me on to another radiology clinic that deals specifically with more in-depth mammograms. BTW... everything came up normal.
I will say, however, that my youngest is now 21, so it has been a while since I've seen an ob/gyn on a regular basis.
Also, I've been with the same primary care provider for 21 years, now..... I like him, and feel that I get good care since I've maintained a professional/care relationship with him.
