Cancer on my back/ not a cyst

This scar is a week and a half old they took out what was thought as a cyst. The biopsy came back today as cancer and the didn't get it all. They have to go back in and get the rest of it out soon. The cost this time at my cost is between $ 775.00 & $1100.00 . I don't ask for help but needing it now.
Thank you.
