Becky,
We always second guess ourselves, don't we?
Don't know any soap science here, but the titanium dioxide in sun screen is usually in a petrolatum base to get it to stick. It is the same pigment used in white oil paint. Remember the gook lifeguards smeared on their noses?
As Becky said, I'll bet the titanium makes the Dove look white and pure, but washes down the drain. I doubt it was left on your skin unless you looked like Mel Smith in Princess Bride:

Antiperspirant has aluminum salts, which would also be radio opaque.
I was totally paranoid about metals during radiation, too. But used Dove and burned like a lobster. I figure the radiation got there. No local reoccurence for two years and counting.
Deodorant wise, aluminum zirconium tricholoro hydrex and the ilk are in standard anti-perspirants. Crystal seems to be dry Aluminum sulfate.
Tried to just cut and paste here, no dice, but look three quarters down the page for BC info.

Darbe, P. D.
here are links to her abstracts on medline:

But search the internet first. Use
"Darbre Phillipa estrogen" and you will see plenty of rebuttal. There was one lage study by Fred Hutchison Center that found no link at all. Dr. Darby evidently does not cite this study.
