Help me beat this thing!

It's been almost 3 years since my health issues first presented themselves and now here we are again, with a 4th occurrence of a cancerous tumor growing (retroperitoneal liposarcoma). I have had 5 major surgeries in this time and all the radiation that is allowed, and now it's back! I have had excellent medical care, but this type of thing is quite rare and hard to get, so there isn't a lot that can be done now. This time I have opted for some treatment that is a bit outside the regular medical field, but still a version of chemo. They have found it to have good success where even the usual type of chemo drugs have not shown to be very effective. The problem arises in that insurance will not cover it. 
So while I hesitate to ask, because it's hard for me to ask for help and particularly for financial help, I am going to ask anyway. I really want this treatment to work and I am hoping there are some people who, even though you may not know me, are willing to join me in this! It is an overwhelming amount of money to me, but for someone else it may not be. And divided out among many, the load is lighter! So, if you are able to contribute, I would be so very grateful!!! I pay for a big treatment each week (just had my first one and it went very well), so the funds are needed as soon as possible. A huge THANKS, in advance, to anyone who is able to help out!
