I am sorry for the loss. My father was diagnosed with Prostate cancer almost 10 years ago. He underwent radiation treatment and we're lucky enough to still have him with us. My mother died 2 months after 911 from heart failure. My dad is now an active member (treasurer) in the Brampton, Ontario chapter of this link. As he says and knows, nobody needs to die from this disease, but so many do. This link is one of the best things you can do for your own loved ones. I am truly sorry for your loss.
