What if I don’t want to go for cancer treatment I feel am too young

I found out I have all the signs and symptoms of breast cancer but I am too young to accept and I don’t want my family to know about it because I don’t have the financial support my family are so poor to support me and I have a three year old son I don’t want to die and live him alone so I am telling myself not to go and know my problem thinking about my outcome just trusting God for healing, so I am confused and weak so what should I do?
