My mam has cancer and it has spread

My mam got throat cancer about 1.5 years ago and she had to have a full Laryngectomy. We found out soon after that her cancer had still spread and she was advised to try immunotherapy (after radiotherapy and chemo)

That treatment worked great and it has bought us some time..

Today I received a phonecall telling me that her cancer is growing in her liver.

I'm scared to lose someone who has been apart of my whole life.

Thinking about losing her makes me feel utter dispair and I need to catch my breath

I want to tell her all this but I don't want her to worry. I want her to know how much I love her and care for her but at the same time I want to be strong for her.

I don't think I have any regrets (we've had a complicated past) but I know she likes to bury her head in the sand. I don't want to enable her to ignore the situation and want to encourage her to open up.

I wish (even hope) I could have a few more years with her, to make her life better and see her happy.

I'm an only child, 34 and she is 68. No other family.
