It is so difficult to watch someone you love die slowly. My uncle has terminal prostate cancer - that is how it started and developed from there to invade the bladder, urinary tract, urethra. The doctors could not operate on him as he would more than likely die on the operating table.
He chose to fight. I fear that his fight won't be for much longer. The rate of decaying tissue and blood that he is passing is absolutely shocking. I visit every second day and try bring a little bit of comfort or distraction.
I wanted to tell you to please check yourselves regularly for any bumps/lumps/pain that should be there - go get it checked out and and if necessary checked again - listen to your body. If something doesn't feel right then it probably isn't.
Also - let those that you care and love for know that you care and love them - all the time. Don't wait for special occassions or disaster to show your feelings.
