I go with science. The science boffins say that no level of alcohol is safe, so I've dramatically cut that down. Can't quite bring myself to eliminate it completely because I enjoy it so very much. However I rarely have more than one or two glasses a week. Processed meat is also a no no, the nitrates. So bacon, ham, prosciutto et al have disappeared from my diet.
Being overweight or obese is a risk factor for cancer, so I'm trying to minimise sugar. When I've done this in the past the weight has come off quite steadily. And it gets easier as you go along because you break the addiction.
If cancer treatment has put you into menopause you need to be careful about your calcium intake. My dietician said four serves a day. It's one of the most easily absorbed nutrients from food. If cholesterol is a problem, stick to low fat dairy. No soft drink or fruit juice is a good idea also. Empty, sugary calories. Fresh fruit comes with fibre is better.
The science round fasting is coming in thick and fast. There are lots of different ways to do it. I tried the 5:2 but it was too difficult for me. My preferred one is trying to have 14 hours between my last bit of food at night and my first bit of food the next day. This is a good evidence based article that talks about cell repair and some other interesting benefits:

Half of our plates should be covered in veg, and there's some hopeful science round several leafy greens when it comes to cancer. And even if it gets disproved, I'll take the fibre, nutrients and low kj deliciousness!
