In the fight of her life w/ Cancer

Good day to you, hoping this finds you in good spirits and well being!!

My name is Ruthie and my mother is Ailene. She is 81 yrs. old and has lived a good life. She raised a family while working hard all of her years.  She still works part time to this day! She has been a mother, grandmother, wife, sister, aunt, cousin, friend to many and she is valued.  She has encountered a diagnosis of metastatic lung cancer as of 1/2017 and we have been fighting and hoping since.  The cost of having the cancer diagnosis not only is the risk to your life and to your days on this Earth possibly being numbered but the cost to continue on with surgeries, chemotherapy, immunotherapy, co-pays, other prescriptions to get by is great.  I have tried to keep it together for her and she will still go to work after being sick all night but at this time I think any help would shine some light on the situation and allow her to have a little bit of peace of mind to continue.
Any assistance for my mother would be greatly appreciated. Thank you so much xo
