Fortunately anal cancer is rare but it can give the exactly same symptoms as piles.
Anal cancer is rare, much less common than bowel cancer. The symptoms of anal cancer can be exactly the same as haemorrhoids, often giving bleeding and irritation. If a person has new anal or bowel symptoms that do not disappear within six weeks then it is important that they have an examination by a qualified doctor. The diagnosis of anal cancer is made after small biopsies of the concerning area have been analysed under the microscope. Most patients with anal cancer require radiotherapy (or X-Ray) treatment to the anus. Some patients require chemotherapy or excision surgery. If you are concerned about the possibility of anal cancer then you should make an appointment to see your local doctor.
