I was very sorry to read your news.
I post this with the same trepidation as I did the first time, simply as a potential area for consideration as an adjunct to what ever treatment is considered appropriate by you and your advisor.

There is sound logic behind why balancing omega three and six (in combination with sound diet) and ensuring adequate long chain omega threes DHA and EPA (found in fish oil) could help reduce inflammation, impact on on cancers etc, but huge amounts are unknown and there is huge debate.
This is strictly a one off "trial", and of limited evidential use.
I have seen another lady making similar claims on Appleseed Annie following a complete dietary change. I am afraid I do not have the link but you can search the site.

If you find this thought provoking please discuss any dietary change with your doctor.
