Hi Nic068,
Those first few weeks of diagnosis are awful, things can become tunnel vision and the rest of the world goes by in an "out of focus" way.
Try to be positive, that you have been diagnosed, the tumour removed and you have a treatment plan. So many don't know they actually have a tumour and from now on you will be monitored.
Whilst we may all have experienced a different type of cancer, many of the experiences are the same, so we know what you are going through.
Go well, radiotherapy is not a picnic, but it does seem a necessary evil. David Craig's Aqueous Cream, helped me with the "sunburn", but check with the oncology team first.
