Paul,
I was moderator on the Rare Cancers Forum Appendix Cancer thread, but resigned as such and was consequently de-activated. I wanted you to know that on FB, in the PMP Appendix Cancer Support Group, there are others with your diagnosis.
https://www.facebook.com/groups/PMPAppendixCancerSupportGroup/Although the group has PMP in its title, it is not restricted to PMP. My appendix cancer was mucinous adenocarcinoma, not PMP. There are many variants of appendix cancer, carcinoid and non-carcinoid represented.
I hope that this is helpful to you.
Alice
