| incidence |
|---|
Squamous cell cancer (SCC) of the anus is a rare disease. The annual incidence is approximately 1 in 100 000, is higher in women than in men, and is increasing. Anal cancer is strongly associated with human papilloma virus (HPV) human immunodeficiency virus (HIV), and immune suppression in transplant recipients.
| diagnosis |
|---|
Small, early cancers are sometimes diagnosed serendipitously following the removal of anal tags. More advanced lesions present as a mass, non-healing ulcers, pain, rectal bleeding, itching, discharge and faecal incontinence.
A relevant history to elicit symptoms and predisposing factors should be documented. Proctoscopy and examination under anaesthesia facilitates biopsy. Diagnosis requires histological confirmation.
