Damion,
Welcome to the forum.
So sorry about your recent diagnosis and the breast cancer too :(
I haven't read any data about a link between UC and breast cancer.
I think you'd be an ideal candidate for LDN - low dose naltrexone. It's been proven to put Crohns' patients into remission, and I've read stories about it curing a few with breast cancer too. So, in your case, it would probably help with both conditions.
Here's the Penn State research done by Dr. Jill Smith with LDN and Crohns Patients.

LDN - low dose naltrexone is very cheap - it costs around $25-30 a month (for pills or the transdermal cream). Gastro doctors usually don't prescribe it because they say "it isn't the standard of care". My gastro refused to prescribe it, so I found a local osteopath who did. I did ALOT of research, and the bottom line is: it works!
Once you get the script for it, you'll need to get it from a compounding pharmacy, who'll make it up for you, and ship it to you. The best compounding pharmacy in the country for LDN is Skip's Pharmacy in Boca Raton, FL. They ship all over the world - they have 20,000 patients with various conditions on LDN. That's where I get my transdermal LDN. If you contact them, they'll tell you who locally to you will prescribe it to you.

Here's my story on LDN: I started on 4.5mg of oral LDN on 2/7/2011, and saw no change - still continuing to bleed at a 10.
When I spoke with the compounding pharmacist, she mentioned that I may not be absorping the LDN properly, and suggested I switch to a transdermal LDN formula, which would be a cream applied to the bottom of the forearm. She told me a lot of her pediatric patients do much better with the Transdermal LDN, and in some patients with absorption issues it helps too. Bottom line is it works!
As far as diets go, SCD - specific carbohydrate diet - is very helpful for UC.
Hope this helps. Good luck to you.
Please let me know how it works out for you.
