"follow up cancer care"

I lost my husband to cancer on the 22nd

August 2015. The length of time he waited for scans and surgery has left me feeling that all that should or could have been done was not done quickly enough and he was passed North Manchester General and Manchester Royal neither hospital could be proud of the length of time my husband waited. Shortened version of what happened is bladder removed dec2013 fought his way back to fitness after checks he was told that blockage in ureter and scan was required it told on 19 November 2014 kidney needed to be removed as only working 9% the saga that followed sickens me and is not what NHS should be proud of. Eventually on the 18 May 2015 (apt given was a cancellation) after 5 hrs in surgery at Manchester Royal it was discovered tumour had grown and was too close to aorta to remove and further tumours were discovered,, nothing more could be done, chemo was mentioned but my husband declined because there was not much positive vibes coming. Now the outcome may have been the same had my husband received prompt care, but nobody knows for sure and that is what I have to live with. I feel it is a waste of time and very traumatic for me to go through complaints procedure as nobody really seems to care.
