[|Human|] Hi My dad is in his 70s and his nose is bleeding continuously for 2 days now. He is int he hospital but drs cannot find a solution yet. He is a nose cancer survivor and used to get nose bleeds often. But not like this. Do you have an answer for this? Thanks
[|AI|]  Nose bleed (epistaxis) in nose cancer survivor can be due to a recurrence or complications of treatment (I presume that the cancer was treated with radiation therapy). If there is no evidence of disease recurrence on examination or imaging studies then complication of radiation therapy resulting in atrophy of lining (mucosa) and telangiectasia (dilated capillaries) is a possibility. If nasal packing with a Chat Doctor. I hope it is of help to you. Please discuss it with your treating doctors.
