Just went to see the oncologist. We looked at the latest scan in comparison to those from August and January this year. He confirmed that there was no discernable sign of cancer cells in the lungs, abdomen and pelvis, so this is the best pre xmas present I could have wished for. I think I was lucky that it didn't get into the bones.
So I am off the chemo for the time being and will have another scan in 3 months time.
