Hello My Friend In Greece Was In Hospital And Found

Hello my friend in Greece was in hospital and found to have abnormal lft,s she had a scan and found had secondary cancer. She is waiting to find the primary. She has been diagnosed with neuroendocrine cancer . She has a monthly injection . Not sure of Name . Drugs to stop the growth of cancer and waiting to have liver tubes blasted / thrombosis to stop them growing . it was diagnosed in dermatology hospital as had red swollen legs so they were checking blood to see w hat was causing it .epiphsitis or something like that in Greek . I'm very sad for her as diagnosed in June and still no knowledge of the primary as short age of dye ! The pharmacist shouted at her yesterday to say why did she not know her primary when collecting her prescription . System different to NHS here . My question is could the swollen legs be related to cancer even though the vascular doc said no problems . She has been obese for many years taking a size 26 and 5ft in height . She is a qualified nurse ,paediatric and children's nurse so has a lot of knowledge . The poor girl would have had better treatment in England . Can you tell me about this cancer and is it slow growing ? Thanks . Worried friend
