I'm so sorry you are going through so much. I will pray for you..There's a prayer line a friend recommended. I'll pm it to you as soon as I get it.
You can contact cancer crackdown I believe they help raise funds for cancer patients by people donating. I'm not sure how the process works. Since you have a diagnosis I'm sure they can help you. http://cancercrackdown.org/
I hope you find your supplements. I used to see an ND he prescribed me a strong solution of lugol's. He told me to paint my thyroid and my breasts daily. As well as take selenium and iodoral work my way up to 4 tablets a day. Dr Brownstein's protocol, even though I personally could not tolerate high doses of iodoral (still took it), probably bc I have hashimotos.
I had a bunch of cysts when I first found cz, they were very painful. My breast pain and lumps went away even though it took a while. I know it's not comparable to Breast Cancer but I was in a lot of pain and it really ended up helping a lot, although it did burn/irritate my skin. I would slice aloe vera leaves and apply them over the breasts to try and heal the skin enough to prepare it for more painting. You can probably dilute the Lugols so it doesn't irritate the skin so much.
You may want to consider essential oils. Amazon has garlic essential oil which I found helpful for an urgent situation I was facing along with other things I used. Also homozon is being used for cancer.
I'm sorry I edited my message bc I'm not in a position to give advice since I'm sick.
God Bless you and I hope you find something that works for you,
Re-edited: I honestly feel it's necessary for me to mention Ozone therapy since it helped me in the past as well, although it was very difficult for me to deal with the detox. Here is a video on ozone therapy.
