 He has received a letter today outlining his diagnosis and treatment. Could someone tell me what TxN1 means please. And also states 65Gy for radiotherapy. Is this standard? Thanks so much again 

Hi. Tx means the primary can’t be assessed, so small they can’t sample it. Best ask your CNS 

N1 means they’ve found cancer in one lymph node 

65Gy is standard. 

Good that he’s avoiding chemotherapy. 

Hi Dani,

Sorry to be a pest.Can you explain to me what the difference is between pathological staging and clinical staging ?

Does path use a biopsy/sample and clinical is more scans etc ?

So many questions !

Thanks Turi

You’re never a pest. 
clinical staging is based on the information the team get from scans and biopsies etc before treatment. 
Pathological staging is that and all the extra information gathered from the samples after surgery 

As you can imagine it’s more accurate. 

Thank you,

Turi

Are you messing with Google? 

Abit.......
