Welcome to the forum Mars0295 although I'm sorry to read that your dad was diagnosed with stage 4 bowel cancer last year and that he's recently been having difficulties with his diagnosis.

I noticed you mentioned he was taking cannabis oil and just wanted to share with you what one of cancer nurses said about this on another member's post: 

Medicinal cannabis is currently attracting a lot of media interest but at the moment ,it remains at a very early stage of research. If a product is used as a medicine to treat a serious medical condition there needs to be evidence to show that it works. There is no scientific evidence at the moment to say that cannabis oil can treat cancer successfully.  Doctors need evidence to underpin the treatment they give which is why this isn't a standard treatment. 

Having said this, sometimes people feel better and more in control of their situation if they feel that they are doing something to help themselves. So if someone did choose to take cannabis oil they should let their specialist know, just in case there are any interactions with conventional drugs.  Interactions might not be known any way, as cannabis oil will not have been tested in the same way vigorous way as conventional medicines.

If your dad's medical team are not aware he is taking cannabis oil it would be in his best interests to let them know as they'll be able to give you advice about this and let you know the impact this may be having on your dad.

Our thoughts are with you and your dad at this difficult time.

Kind regards,
