I’m on it for side effects from the hormone suppressing tablets I’m taking, as my ca was hormone positive. Don’t change your diet too much, but yes, try to keep it alkaline. Ca can’t survive in that environment. Drink a glass of water with a teaspoon of baking soda in it. That makes the body alkaline. And check food properly, as a lot of vegetables are acidic, so going vegetarian for example doesn’t guarantee an alkaline environment.
These questions and thoughts are normal, I’m pretty sure we all went through them. I know I did. But also try to eliminate stress, as that creates acidity in the body too.
