Can Cold Cap Prevent Treatment From Working?

[Freakzilla]

Hi Guys,

In two weeks time my wife is starting IV Taxotere, Herceptin & Perjeta, as well as IT Herceptin. She will be having a maximum of 6 doses of taxotere, although we hope less.

3 years ago my wife had 6 cycles of Fec-T, she used the cold cap and kept most of her hair.

My wife had Dura mets treated by Gamma Knife 3 weeks ago. My wife is concerned that if she has uses the cold cap, it will stop the treatment from reaching the Dura. The onc didn't seem to think it would, and I can only that cold cap might not be effective for scalp mets.

Anyone had any experience of this?

Thanks
