"Colon cancer with multiple metastases"

I have been a patient in Royal Marsden for 7 years. My primary cancer was colon and treated well. Then I showed metastases at the lung that took relatively good care of me. Then metastases at brain and spinal cord. To make the story short, I tried every possible treatment but unfortunately didn't work. The main issue is that as a palliative patient now I haven't been treated properly and there have been many mistakes that took me to hospital and they could have been avoided if the drugs and check ups have been given properly. At this stage of my disease I have been left in my own destiny, and it is very sad to encounter that especially if I have been a patient at this hospital for many years and had very good opinion before.
