If they don't find anything on the second series of tests, could she avoid chemo?
I don't know.
Her cancer was similar to mine, in that the cancerous area could have spread through the lymph nodes to other parts of the body. I had the surgery, and "close observation" to confirm that it hadn't spread to the lymph nodes. Because it hadn't spread, I didn't have chemo/radiation.
If it is determined that is hasn't spread, there's no need for chemo.
