My Dad’s prostate cancer operation

My dad is the most hardworking person i know. He is now 76 years old and his work involves buying grocery items and selling them to market vendors for a small profit (and receive payment of around 40 cents per day until fully paid). All of which is done by walking to the grocery and walking back to the market.

He never went to doctor for checkup, but we insisted on it. Long story short, doctor found prostate cancer on him, normal PSA is 0 to 4, his was already 75.

Operation was 600,000 pesos (around 12000$), excluding medicines. Me and my sister are employees and this amount is a big burden on us. My parents don't have health card (over age) nor significant savings.

Any help would significantly help our family. The entire bill is currently in my credit card. I'm so much worried because based on the biopsy, there are already cancer cells in the prostate surface, hoping for your prayers and if possible any financial support will be highly appreciated, thank you so much.
