Help my mom with medical expenses due to cancer!

My mom, Joanne Lafferty, has stage 4 metastatic breast cancer which has spread to the liver. This is her third time going through Chemo. This time is by far the worst, so she is unable to work. She has to spend hundreds of dollars every month on medical bills, aside from her regular bills. Without any income at all, it makes things very difficult. Every penny would help her out right now, and be greatly appreciated!
