Co2 camber. There is a really good YouTube video that shows how to humanely put the rats out. Can I send links on here? I can send it to you for instructional purpose. So you can decide what to do. But it's the best and most humane way to go about it.
That sucks they have tumors. But you're a good person to reach out about it first and ask for advice and to put them down.
There are several U-tube videos on cervical dislocation.
I generally use an empty tin can that had one end cut out with a can opener. Holding the mouse by the tail, put it on a sturdy surface. Place the open end of the can over the mouse's head. The can's edge is positioned on the mouse's neck. Press the can down hard.
The mouse will kick for a short time and sometimes bleed from the nose or mouth. Immediately dropping the mouse in a container of some sort will minimize that.
I've never done it, but I think a snap mouse trap could be screwed down to a heavy piece of wood so it wouldn't fly up when triggered. That would make a decent cervical dislocator.

Only if it hits the right location though...a mouse neck isn't a big target and mice do not lay still. For those who are at all squeamish, this is probably the wrong method.
