Help Helena beat metastatic bone cancer

My mom is 67 and very loved by her kids and grandchildren. She was full of energy and life.  On 3/17/2021 we received a devastating call that she has cancer.  The doctor tells us it's metastatic bone cancer. We started researching everything about it while tears were pouring down our faces.
When a cancer spreads to the bones, it’s called bone metastasis. It’s also called metastatic bone disease or secondary bone cancer, because the cancer didn’t start in the bones.

Bone metastasis usually occursTrusted Source in people who have been previously diagnosed with cancer or who have advanced cancer. But sometimes the pain of bone metastasis may be the first sign of cancer.

Bone metastasis often meansTrusted Source cancer has progressed to an advanced stage that isn’t curable. But not all bone metastasis progresses rapidly. In some cases, it progresses more slowly and can be treated as a chronic condition that needs careful management.
We want to help with treatment and her insurance doesn't cover a good portion of the medication. 
Please, I'm begging anyone that will listen, HELP, please help this amazing person. 
Thank you from the bottom of our hearts. 
Alex, Ivana and Helena.
