Thank you for your query.
Sorry that your friend is going through this.
Cancer and it's treatment takes a toll on the body in addition to suppressing the immunity.
Prolonged hospital stay with long standing intravenous catheters also pose threat of infection.
Major surgery with post operative infection along with metastatic cancer has a poor prognosis, in terms of life and its quality.
When a cancer is inoperable, your friend will be offered
palliative care (where measures, surgical included, are taken to keep him as comfortable as possible).
Options of chemo or
radio therapy should be discussed with the doctors to see if the benefits outweigh the risks.
Some don't tolerate these therapies well & it makes for a poor quality of life.
I'm sorry that this is all the advise I can offer you.
Hope I've been helpful. Please let me know if I've been helpful.
Wish he feels better. Wish you good health as well.
