Cancer patients (once their radio/cymo therephy is over) are usually told to relax and do enjoyable things, such as having parties, holidays, country walks, so the sun-bed is not unusual (unless your friend has skin cancer). Some cancer patients look very ill, others (due to the type of cancer) look no different then before they had cancer. Remember Jane Tomlinson? She was given 6 months to live but died about 7 years later. During which time she received telephone calls from people saying she was a fraud and that she did not have cancer. So be careful what you say!
