Donna--I can't comment on the exercise bit, although I have seen various articles suggesting that daily exercise does help to keep breast cancer at bay.

I have read a lot about flaxseed (ground, not whole) as a way of diminishing the HER2 protein. There are artciles posted on this site and on the internet regarding various trials using flaxseed. Also Sloan Kettering has a supplement site where you can read about benefits of flaxseed. The Canadian study, a controlled study, gave women diagnosed with breast cancer before surgery a flaxseed muffin each day (25 grams in each muffin) and found after surgery that both the KI67 proliferation rate and the HER2 protein had diminished. It was a significant reduction, although I don't remember the number.

I started out baking muffins but it was a bit time consuming (and they were so good I was eating too many), so I started mixing it into my cereal (Irish oatmeal) with skim milk. Not the greatest taste in the world but okay.

So, I would say if you're not ER/PR positive, for sure flaxseed can't hurt. Some claim that flaxseed can increase estrogen, although that's up in the air right now.

Remember keep the flaxseed refrigerated, and grind fresh every few days.
