Good morning, @bronthebrill. The first words out of my mouth when I read your reply to friends gasping at your decision of what your eating would be: “Mind your own beeswax!” LOL. Having had cancer myself, I refrained from telling too many people for that reason. The buttinskies!

There isn’t any one thing that you did to get cancer. Just being exposed to life itself with our environment, pesticides, contaminants, pollutants, stress, gamma rays, you name it, can cause a single strand of DNA to go rogue and cancer takes off.

I found a great discussion in the forum that contains this blog post about sugar and cancer plus responses from other members with a variety of cancers.
~Should sugar be eliminated from diet in a cancer patient? https://connect.mayoclinic.org/discussion/should-sugar-be-eliminated-from-diet-in-a-cancer-patient/

Getting back to how you can respond to unsolicited advice from friends, because telling them it’s none of their beeswax isn’t the best way to handle that. ☺️
These worked for me:
~Saying, “Thanks for thinking of me” and then carry on.
~Ignore it
~”I appreciate your attempt to help, but I’d rather talk about something other than my health. “

There are also several members in the forum who also have been diagnosed with ILC-Invasive lobular carcinoma
I’m posting a link to search results for ILC. You can scroll through the discussions. Feel free to jump into any of the conversations. https://connect.mayoclinic.org/search/

How are you doing with your treatments?
