Help for Claudia

Claudia is my older sister so someone I look up to and automatically respect ( if I don't she will make me). This picture of her is just before she was told that her cancer has come back nearly 5 years later.
She has been a single mother to her beautiful daughter for the last 15 years. Her daughter is now 18 and going off to college in anticipation of going to go into medical school. Claudia had been engaged about 6 years ago but in that time he developed malignant melanoma in his later thirties and passed away suddenly from complications of it. One year later Claudia was diagnosed with cancer of a rare type of tumor in her upper nasal passage that started with significant congestion and nose bleeds. This obviously is very scary anytime diagnosed with cancer and when she also recently lost someone she loved from it.
Claudia was plagued by healthcare costs from her situation and continues to pay monthly on these to this day.
This time cancer was again in her nasal passage but now also in a lymph node on the side of her neck. This has resulted in a very large incision, partial facial paralysis, numbness, and also nerve pain.
She has undergone surgery (at Mayo Clinic due to the rarity of this type of tumor) at this point for the cancer removal but now is going to need daily radiation due to the fact that the cancer came back. Further appointments pending as chemotherapy may also be needed due to the reoccurrence and finding in her lymph node.
I am reaching out for help of any type of donation for her. As I mentioned she is single and as her close family we are trying to help all we can. She may lose her home again as was forced to sell the first time due to costs. She is unable to work at this time, she works as a dental hygienist and wearing the masks all day is painful and with radiation to start in the area the mask situation is not going to help. Plus just dealing with pain and fatigue. Treatment will be about 45 minutes away from her home. The money would go towards her apartment costs, car payments, gas for travel, food, etc. We are also concerned with her daughter entering college and the costs associated. Financial aid is already being applied for.
My sister is sad, stressed, and uncomfortable. Knowing she has some support from you I am hoping will relieve some of her stress but lift her spirits as well. She feels very alone and targeted by this.
Thank you for your time and reading this.
