OMG I am so sorry for your friend. I am so sorry they made her wait.
If you are interested, I have metastatic cancer and have done a lot of research on it. In brief, I was diagnosed with inflammatory breast cancer in 2004 and given 6 months to live, but I did a bunch of alternative stuff in addition to the chemo, etc., and I'm still alive 17 years later. Recently the cancer came back and I am once again doing alternatives as well as doing conventional treatments.
I would be happy to share information with you IF you think your friend would be open to trying alternatives. EVERYTHING I do, I've researched - if it's not in a proper medical article and has studies done, I don't do it. Much of it is very affordable.
I recently wrote an article on one thing I am doing.
