Most women will never have symptoms. Yet, the main symptoms are burning, itching, irritation, rectal or anal bleeding. In more advanced stages, there could be anal discharge, ulcers, lumps and abscesses.
The only way for anal cancer to be found is to have a full examination by a doctor. However, getting an abnormal pap test of your anus could be a sign of cancer or dysplasia.
Your doctor may also use a DRE or digital rectal exam to diagnose issues. This is where they will use a gloved finger that is fully lubricated into your anus and rectum to feel for anything abnormal.
If you happen to have any symptoms, then your doctor may then recommend an anoscopy as well as a biopsy. It is very important that you talk to your doctor about getting checked for anal cancer regularly.
