I have been following this wonderful site, since my diagnosis of Bowel Cancer in May, 2019. I have always cooked & ate very well...However, I love meat. Yet also, I drink wine & smoke - so, possibly a candidate for cancer.
However, I have read on this site of Vegetarians, non smokers & non drinkers - that have also succumbed to Cancer.
I now have a good friend who is Stage 4 Bowel Cancer - who has never smoked, & rarely drank. My daughter told me today that a good friend is now in ICU with Lung Cancer (age 47 yrs.) again not a smoker/ drinker.
I think that there is no rhyme or reason why some of us succumb to cancer. It could be genetics, or maybe pollution in general. I often think it's ridiculous that some people hate the smell of smoke, yet ignore the awful smell of diesel fumes on our roads.
I don't suppose that we will ever discover the reason for cancer - unfortunately.
