Michelle's breast cancer expenses

Hey all, some of you know that I am a breast cancer survivor but some of you may not.  I am a survivor of coming up on 5 years now.  I had to use up my 401k to pay for treatments but that wasn't enough!
I went in for a routine mammogram and they found another mass in my other breast.  I had a biopsy and they found no cancer cells in the biopsy but they want me to have it removed anyway because I have a 15% chance it turns cancerous.  
I just received the statements for the biopsy and as much as insurance paid, I still owe a bundle and of course they want all the money at once and I don't have that kind of money especially since I used all my 401k for the initial treatment.  And now that I have to have surgery to remove the mass, I just don't know how I am going to survive all the medical bills coming in!
If you can donate, please any little bit will help and I so much appreciate it more than I could ever express!
I thank you all in advance, Michelle
