Hi Penny...wow, that is a large size polyp. Since it's already cancerous, the removal of your entire colon is probably the best safeguard for your future, both emotionally and physically.
Age, although sometimes a determining factor, seems not respectful regarding cancer. If you didn't have UC or a doctor who didn't do as indepth testing, you may have never known regarding the polyp. It's good we're tested for cancer.
Since you do have the lump in your liver....I would assume you'd have another test in the future to make sure it's not showing any change. Something for you to note at least once more within a few years.
I suggest you get copies of the reports from ALL your tests to have for your records. Many ask lots of questions....always good to know the answers.
Looking forward to hearing how your appointment with the surgeon goes.
How are you feeling today?
how is your mom doing through all this?
