Funds needed for a tissue expander that needs to be removed after cancer and mastectomy

Dear friends, last year, I discovered a lump in my left breast. It was cancer and I had 4 surgeries in 2 months time. I lost my breast. Thank God I am cancer free. However we really struggled. My husband gets a small pension of which most goes towards the medical aid. Then to top it all, I was involved in motor vehicle accident and almost lost my car. Had R90 000 damage. We managed to save it through panel beater who fixed it for R42 000. On the 23rd of January 2019, I had my 5th operation on my breast. This time to insert a tissue expander so they can try and rebuild my breast. I am now scheduled to replace the expander with the permanent prosthesis. There are consultations at the specialist and prescriptions as well as part of the previous operation, which my medical aid didn't cover. I received a notification from the specialists admin that if I do not pay R11 000, they will not proceed with my surgery. I am so tired of all the worrying. I will also have to raise funds to pay for a mastectomy on my other breast, because medical won't pay for it. The specialist wrote motivational letters because there are plenty of breast cancer in my family. We had no success with them. So you see I will have to pay for it myself to save my life. Any help would be highly appreciated. Thank you.
