Gale's medical expenses

My wife Gale was diagnosed with breast cancer and a tumor in her brain last May while we were attending our daughter's graduation in the States. We had to take her to the ER at Mercy Medical Center in Redding, CA. We have been blessed not having to pay the $ 160,000 US bill for the 14 days she had to be hospitalized there. But we have been receiving bills from doctors, tests, care and other type of services that she had to go through during her stay in the hospital. We have been trying to negotiate with these services but they are still sending their bills to us. We returned to the United Kingdom where we serve as International Christian workers and our salary is not enough to pay all these bills besides other current extra expenses related to Gale's health. Medical treatment here in the UK is free but still we need to pay something for her medication.
We are starting this campaign to raise the funding to pay off this medical bills and use some of the extra funds to pay for her current health expenses.
