I have a friend, recently retired who lives in the UK but spends each summer here in her home in the Poitou-Charentes. She has recently been diagnosed with breast cancer and will shortly begin either Radiotherapy or Chemotherapy treatment in the UK. Can anyone please give me any information relating to her being able to continue that treatment here during July, August and September,, and whether the costs involved could / would be met by the National Health Service, (?E111), or must be funded by herself? Lastly, can anyone tell me the nearest Radiotherapy / Chemotherapy treatment centre to Civray or Ruffec? Very many thanks. P.T.
