I think you can, and I certainly hope you can. But I'm not a legal person and can see hoe this could be an issue. I suggest you contact a local flotilla or division. They have access to a division or district legal counsel who is in the CGAux. They can get you an authoritative answer, and get it to you in writing. Good luck.
And us cancer survivors need to stick together. I lost a chunk of my thyroid to cancer about 30 years ago. I tell people I'm not all there.
