Help my father get radiotherapy for cancer

Hello to each one of you who is reading this page. I am raising this fund for my father who is a 62yr old retired Indian government Employee, a loving grandfather, a caring father, an understanding husband, a devoted son and a selfless elder brother to his siblings. He has been through a lot of ups and downs in his life and has been headstrong in his decisions for the betterment of his family and friends. People who know him respect him for his knowledge, empathy and crisis management. Today he's in a huge crisis of life. My parents visited us from India for birth  of our second son. Luckily, they were here before flights got cancelled because of Covid-19. We applied for extension as the flights were still not resumed. Their visa stay and visitor medical insurance expired end of August 2020. When we were enjoying the unexpected longer time we got, to stay together inside home, little did we know, that we have this tragedy waiting for us. My father for the first time in life, got a sudden seizure on Sunday, 6th of Sep.2020. The 911 team helped him in immediate aid and moved him to Good Samaritan Hospital, Los Gatos. They did MRI, CT scan, and number of other tests to find out the reason behind it. Unfortunately,  my father is diagnosed with very advanced stage of brain cancer,  multiple metastasis in brain. Doctors want to start with radiotherapy as soon as possible. Me and my husband, have been trying our best to deal with all the finances that we can for his best treatment. But, we feel, we might not be able to do it without some help. While in India his company is going to take care of all the expenses for his treatment from beginning till end. Those of us staying in US,  know that even the richest of all, can't think of getting medical treatment without insurance. Please help us to start his preliminary treatment, so that he is in a health condition to atleast travel back to his country and continue with remaining treatment and meet his old mother- my grandmother,  who is waiting desperately for him to come back home. Every day counts. I request you all to help us in beginning this long day that lies ahead.
Thanks in advance.
