Tammy's Cancer Expenses

My mom, Tammy Killebrew, has recently found out she has cancer. It started with bumps that had came up all over her body that starting growing the size of a tennis ball all over her arms. They hurt and burn constantly but since she didn't have insurance she waited until about 2 months ago to go to the doctor. The ER sent her to a dermatologist who done a biopsy. It came back skin cancer. We was sent to TN Oncology and sent for a PET scan. ALL of these appointments have been paid for out of pocket because she keeps getting denied by Tenncare. Today, we got the PET scan results which also show a spot on her left lung and her bones in her chest area. She now needs biopsies done for her lung and bone marrow that we have to pay for out of pocket, the first being on her lungs on June 12th so we know what the spots are exactly and what stage the cancer is in. Haven't received a call to tell us the exact amount she has to pay yet since we just got the results today. My mom has been through a lot. Lost her Dad, husband, then her daughter, my older sister. She works as a waitress at 2 different restaurants 6 days a week to keep up with bills since she lives alone. As soon as we get the amount for these procedures I'll post them but since the first biopsy is next week we need help asap. She'll be having to miss work due to these test and having radiation done on the skin cancer spots. She hates asking for help, but were currently trying to find an insurance for her that will start helping with these expenses immediately instead of having to wait a certain amount of time after becoming insured with them. Absolutely anything will help, and please keep my mom, my Nana, myself, and our family in your prayers.
