I am new to the site and happened upon the in memoriam section and decided to read. The passing of your husband is a tragedy, and i ran into similar problems a year ago. While I had been going to my GP with complaints for 2 years, there was little ever said or done about them. Finally, last June I was in so much pain I couldn't even walk any more. A quick digital exam revealed what was later determined to be a fist sized tumor in my colon.
I was diagnosed with 4th stage colon cancer and told by doctors to get my final affairs in order. It had spread to my lymph nodes and liver. I was fortunate that I survived, and I am currently "cancer free"
But you are right… if you ever suspect a problem and your doctors don't seem to think it is a big deal, but deep down inside you know it is, seek a second opinion. I am fortunate that I am still here to tell you about this. I only wish that Rick was still here as well.
My most sincere condolences.
