Hi Amy,
Welcome to the OCF forum. I would like to suggest that you post under your own topic so that it gets the attention it deserves and does not get overlooked. What you do is go to the main Forum List, click on the Introduce Yourself topic, then click on New Topic in the upper left hand corner.
What you might also do is post some answers to the following questions:
What stage of cancer does your father have?
How old is he?
Who is his caregiver?
Where is he being treated?
When did he finish treatment?
Did he have any surgery?
Does he have a PEG tube?
What kind of symptoms does he have now? Weight loss, mouth sores, a lot of mucous in mouth...etc.
Once you start your own post and include a lot of this information, there will be a lot of people on the forum that can help and provide you will a lot of information.
Look forward to hearing from you.
Tom
