 [ Symptoms ] can a fracture cause a fever [ Disease ] i am sorry to hear your dad is going through this it sounds frightening i would not jump to an immediate diagnosis of cancer while this unexpected bleeding certainly should be investigated by a health care professional there could be many causes for this bleeding that have nothing to do with cancer that said i would suggest your dad see a health care provider as soon as possible any time a person develops a new symptom such as bleeding it is worth getting it checked out hope this helps wishing your dad all the best
