Well that's no fun Debbie. If it was me I would be wanting the tumor out while its small. I think my chemo I had and the hormone pills messed with some of my cells and now I am just quirky in that a tiny injury can develop into a whole tumor with no good reason. Fortunately I haven't had anything in the brain though.
If you are living alone I am wondering is your diet right? You can do a lot diet wise to help stop cancer returning. Cruciferous vegetables, turmeric and some herbal teas can all help keep your body in tip top health.
