My mom and we need help with chemo treatment

Hi, This is my mom and we recently found out that she has Stage 4 Metastatic colon/liver Cancer. She have insurance but is on a fixed income and her out of pocket plus the port placement is $3900+$175. We just can’t afford it. Please help us, once that out of pocket is satisfied then 100% will be covered for the rest of the year. Thank you for any help!
