My brother is about to leave hospital this week after being there for six weeks, having had massive chemo then a stem cell transplant to try to rid his body of NH Lymphoma. His wife has invited her sister and 5 others to stay. They are flying from America and staying for 2 weeks, arriving the day before my brother comes out of hospital. They will be going to London each day on the tube and visiting restaurants and theatres. Should they stay elsewhere to reduce risk? Cant scroll problem list
