I could be a good example of this. In 2015 I was I was diagnosed with colon cancer and had it successfully treated, as is been shown by one more successful colonoscopy taken only about a month ago. I’m 81 and in spite of the number of problems, one I do not have is having lost any of my marbles.
My late mother had both. She passed away due to cancer before the Alzheimers could do its worst however. They did an operation but couldn’t get it all and it spread. I looked after her with Alzheimers for about 6 years before that.
