I want to save mommy and give her a chance for life

My name is Lena, I am 21, we are from Ukraine, the city of Kharkov. I am asking for your help in connection with a difficult life situation. My mother has stage 4 melanoma (this is a very aggressive skin cancer that is not affected by chemotherapy). We have gone through 2 surgeries to remove the metastasis. But unfortunately, cancer is very aggressive and progresses rapidly. Metostasis is now found in the lungs, liver, bladder and under the skin. And the only chance for life is undergoing immunotherapy treatment, lasting about a year. (The drug Keytruda, 1 bottle costs 45000 UAH, and such a month you need 3.

For our family, this is simply unbearable and cosmic money. My mother devoted her whole life to medicine, having worked for more than 40 years in a hospital as an operating nurse, and every day she helped doctors fight for the lives of people, and now she is fighting for her own life please help to save give my mommy at least some chance for life
