I have had small discharges of blood from my backpassa
ge since having radiotherapy. In the past they have been small spots and smears. A sistoscopy in July 2017 indicated that there was nothing to worry about and this happens after such treatment. In the last few weeks however these discharges have become heavier and the blood is almost black in colour. they can happen with little warning and I am worried when I leave the house. I am due to see my oncologist next month, but am unsure whether I should seek advice in the meantime. Can anyone advise?
