I am 73 and was first diagnosed with breast cancer when I was 39.  I then went on to have two lumpectomies and when I was 51 a mastectomy and radiotherapy, right side.  When I was 70 found a lump on my breast bone, eventually had a second mastectomy and radiotherapy.  Found out last November that I now had bone cancer, incurable.  I am on Palbociclib in tablet form  which is an alternative therapy. 21 days 7 off.  I cannot take the 21 days it is too much for my body to cope with.  I go to see my consultant a week today and I am going to tell him that I will take 14 days but then an alternative treatment or lower dosage must be given.  He did tell me at one meeting that he did not want me to suffer, we shall see how it goes down.
