I considered them about 15 years ago when I was diagnosed with breast cancer. I couldn't justify the distance then from my home to the regional hospital but now they have several different locations and the trip might not be so long.
Tell your friend to put away the "pride factor" and allow/let people help them. It takes a large village to help a person with cancer to get through it. It takes people you don't know who will step up to the plate and do something that you can't. When it is a man it becomes a "man thing" about providing for his family as that is part of a man. I know because my husband went throught this when he was diagnosed with advanced prostate cancer and had to stop working. It was me who pointed out how he helped the family without working and to put it on paper so that he could see it and relax a bit. Our roles have changed quite a bit as I still work and he is at home. He is on chemo now but the team of doctors that he has are going everything they can to help him live a good and comfortable life. I know that there will be a time one day that this is not so and I don't run around with my head in the sand.
Have the wife take pictures and have hubby write notes to the son. Let dad think of all the things he wants to tell his son so that "just in case" he does leave before that age he will have something for the son to read and understand. Dad should use a recorder so that the voice is heard and son can get a feeling of being closer to dad than just the pictures alone.
The things that have to be done around the house are things that other people can do to make their lives a little easier. I know easier said than done but it is true. Lean on the friends and family that are helping. They wouldn't be there if they didn't want to be.
Above all else have her take care of herself. Make sure she gets rest and a break from the strain of being a caregiver. Make sure she keeps her appearance up. Get her out of the house and to a movie or a day at the spa or have a glass of wine with her at her home. Make it a girls night out or in depending on the weather. *I say this because of the show What Not to Wear when they have a person who has been a caregiver who has lost their own identity.*
Many heartfelt thoughts and prayers for your friend and friend's family at this time of the year. Let everyone stop and smell the roses. They really are pretty even at night when most people can't see them.

PS Cancer survivor now caregiver to hubby. I work to keep my sanity and my personal space. There are things that I need to do but don't have the energy anymore to do them as I used to. One day they will be done.
