My Mothers Oral Cancer Treatment

I am from a poor family My mother is 55 Years old

i don't know when my mother started to get oral cancer symptoms but as poor family we dont have that much money to do regular medical checkup.

but since last year my mothers condition has become worse ( suddenly)

i am now 21 i don't have a job my father died when i was 5.

so basically i dont have any money to cure my mother so i ask help from everyone.

please help otherwise my mother will die.
