How are polyps diagnosed?
Your doctor can diagnose a polyp by:
- asking you about your medical history and your symptoms
- examining you
- doing medical tests, depending on the polyp they are diagnosing, such as an ultrasound, colonoscopy or hysteroscopy
If your finds a polyp, they may recommend a biopsy. If the polyp is difficult to reach, you might need a procedure such a gastroscopy, colonoscopy or hysteroscopy to get the biopsy.
Sometimes, you may find out you have a polyp as a result of a screening test. For example, you can learn you have a bowel polyp during a faecal occult blood test (poo test) used to screen for bowel cancer. A cervical polyp can be found during a routine cervical screening test.

How are polyps treated?
Treatment for your polyp will depend on:
- the type of polyp you have
- what part of your body it's in
- if your polyp is cancerous
- how many polyps you have
- their size
Sometimes, you will need treatment to improve symptoms. Some polyps need to be removed, while others should be monitored to reduce your risk of cancer.
Examples of some treatments include the following:
Uterine polyps
If your uterine polyp is causing symptoms, your doctor may prescribe medicines to relieve them. If your polyps are causing fertility problems, your doctor may recommend surgery to remove them.
Colorectal polyps
Colorectal polyps may be removed during a colonoscopy.
Gallbladder polyps
If the polyps in your gallbladder are larger than 10mm, your doctor may recommend removing them with surgery. If your polyps are smaller, your doctor will check them regularly.
Throat polyps
Polyps growing in your vocal cords in your throat can be treated with:
- resting your voice and avoid shouting
- drinking plenty of water
- treating reflux, if you have it
- having voice therapy with a speech pathologist
- surgery
What are the complications of polyps?
Whilst most polyps are benign, some may turn into cancer if they are not removed quickly enough.
For example, most bowel cancers start off as harmless polyps. If they are not discovered and removed, they can turn into cancer.
Can polyps be prevented?
You can't prevent most types of polyps. The best way to check for polyps is to visit your doctor regularly for health checks. This way, your doctor can find and treat polyps early.
All Australians aged 45 to 74 years should do a screening test for bowel cancer every 2 years.
All people with a cervix aged 25 to 74 years are recommended to have a cervical screening test every 5 years.
If you have a family history of polyps or certain genetic conditions, you may have a higher chance of getting polyps. If you are at risk, talk to your doctor about how to prevent them. Your doctor might suggest you have other regular screening tests.
You can lower your risk of some polyps and cancers by:
- eating a healthy diet
- exercising regularly
- losing weight, if you live with overweight
- avoiding smoking
- limiting alcohol
