Complaints that are consistent with anal cancer are loss of blood or mucus from the anus, pain (when sitting or defecating), itching at the anus, feeling more or less urge to defecate and sometimes there may be a swelling or lump near the anus .
Also, someone can lose weight without being actively involved in losing weight. Many of these complaints can also occur with hemorrhoids (a hemorrhoid is not an HIV indicator condition). The GP can distinguish these disorders from each other.
