I have adenoid cystic cancer, very rare I know, but it was featured in a story line on Holby City in a very negative way with the word's " your cancer will kill you"! I rang the BBC but can't get this out of my head as I have been so positive so far and this has really messed my head up. The doctors diagnosed it as a rare primary breast cancer so I had a mastectomy and radiotherapy a year ago and have my oncologist s appointment next week.
