My dad has cancer, please can someone explain? (14 year old girl)?

Cancerous nodes are cancer growths. When they opened up your father and did not do anything that is because it is too far gone to help him survive, we don't know how long he will have but when my dad had cancer and it spread to his liver he died within 6 weeks, you will need to be there for your mum and pray for your dad as the pain will get unbearable near the end and he will hallucinate and talk rubbish so if he doesn't know who you areor says something horrible to you or your mum don't take it seriously as he wont know what he is saying.
