Sick best friend needs help.

My friend Bean (7 year old Pit Bull) has a mast cell tumor (cancer) that needs to be removed and I can't afford to pay for her surgery.  Asking for charity is our last option and not something I am comfortable with but, as her "dog dad", the single person in this world she looks to, to keep her safe, healthy, and loved watching Bean suffer and being powerless to help is unbearable.  I know things are tight for a lot of people right now but
if able, please help Bean beat her cancer and live a long, full,  happy life.  Thank you for any help you can offer us.
