Sometimes anal cancer does not cause any symptoms at all. Bleeding from your rectum is the most common symptom of anal cancer. Other symptoms can include:

• Pain or pressure in your anal area

• Itching around your anus

• Discharge from your anus

• Swollen lymph nodes in your anal or groin area

• A lump or swelling near your anus

• Narrower stools

• An increase or decrease in bowel movements

• Straining during a bowel movement

Many of these symptoms may be caused by other health problems. But it is important to see your healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have cancer.
