I have a father in law who has just undergone radiotherapy for 3 weeks 3 times per week . After finishing seemed ok but then got rushed to a and e with sepsis . Now being treated with fresubin drinks and undertaken a course of rluclox 3g drip . . Is there a time limit to life expectancy for this treatment as nobody seems to be telling us or do we need to ask . My husband is very timid and would not ask these questions. Thankyou
