Chemotherapy and radiotherapy related.

Hello My mother got diagnosed with breast cancer and had her surgery in LNJL hospital Delhi on 23/02/2021 and the doctors told us to get chemotherapy and radiotherapy after 5 weeks of surgery but now they say that its not available in the hospital as its a covid hospital now. They refer to another hospital but all the hospital are denied for the chemotherapy because they all are covid hospitals. As i am not financially well person so i cant afford a private hospital. I want to ask that how much time can we wait for the Chemotherapy and can we go to our hometown for 10-15 days as the situation here is bad and after few days get the chemotherapy and radiation therapy? I have shared her after surgery biopsy report. They had removed the whole brest with tumor. Please answer asap how much time we can wait for the surgery. Is there any chances to go this cancer in advance level. Thankyou
