Shirley's Alternative Cancer Treatm

I have metastic breast cancer - it is in my left breast, a couple of lymph nodes, and in my lungs. I have not wanted to do traditional therapies, such as surgery, chemo, and radiation. Recently (7/20/17) when I became very short of breath I was hospitalized and found that I had a pleural effusion (large build up of fluid in the lining of my right lung). They extracted nearly 2 liters of fluid and there were cancer cells in the fluid. It appears that the fluid is already building up again. The fluid showed that my cancer is estrogen positive. The oncologist wants me to start on estrogen blockers and get a PET scan. I have found a well known clinic in Mexico that has helped many people - even with stage 4 cancer like me. It costs $19,000 for a 3-week stay at the clinic.  I am on Social Security and only have $1590 income a month. I need help as soon as possible to get treatment at the clinic.
