Hi, I had my six monthly check up 5 weeks ago.I have not had the results back yet and I know no news is good news.I had my kidney removed 18 months ago(had a tumour) Since then all my CT Scans have been clear,its waiting for the results saying see you in six months.Just a quick question or looking for a bit of advice.Over the last six months I have been really tired I don't know if it the heat or not drinking enough water…
