Unfortunately, whatever scans or surgery may show there is a possibility that unseen micromets can exist and go on to establish elsewhere which can become evident in many years after treatment, so this should be remembered and men still monitored. This may well result in a man becoming over concerned about things that may well not be PCa related. The chest is not a frequent site for PCa especially if the cancer has not already established elsewhere. However, whether a man has PCa or not the general advice is that a persistent cough should be investigated because it can be a symptom of other problems My daughter has only recently been discharged from hospital where she spent 2 weeks with a severe chest infection, although in addition to a cough she had pain if breathing other than shallowly. .
