If you have anal cancer, you may bleed from your rectum, which you may see in your faeces or on toilet paper, have pain in your anal area, develop a mucus discharge from your anus, feel small lumps around your anus, experience itchiness around your anal area, have difficulty controlling your bowel movements(faecal incontinence) or feel a lump in your groin. These symptoms aren't always caused by anal cancer but if you have them, contact your doctor.
