Adjuvant chemotherapy for a rare cancer

My mom has been diagnosed of a rare cancer, high grade endometrial stromal sarcoma stage 1B. She had an operation last month - July 20, 2017. As an adjuvant therapy she will need chemo. She is almost 61 years old, no job, no health insurance or savings, no husband and I'm her only child. She started getting sick in 2014 and since then I've been supporting her. I was able to get funds for her surgery, but with the increasing bills I'm paying, we won't be able to afford chemotherapy. I'm putting this up to ask help and extend my mom's life. This rare cancer is very aggressive and not so much information about it. But we are hopeful she pulls through and survive this
