Tumours of the Nose and Sinuses
A tumour is the name for any kind of swelling or growth and can be benign (non-cancerous) or malignant (cancerous). Those that affect the nose or sinuses are referred to as sinonasal tumours.
What are tumours of the nose and sinuses?
A tumour is a swelling or growth that occurs when cells grow abnormally. A sinonasal tumour is a growth in the nose, the space behind the nose, or the sinuses. Sinonasal tumours are rare, with only 10 in 1 million people affected each year.
Tumours can be split into 2 main types:
Benign tumours
Benign tumours grow slowly and do not spread to other parts of the body. They are usually not harmful, but can cause issues if they grow large and press on other organs or tissues.
Examples of benign sinonasal tumours:
nasal polyps – a swelling of the lining of the nose
inverted papilloma – a one-sided, warty, slow-growing tumour that can be similar to a nasal polyp
haemangioma – a collection of blood vessels that usually causes nosebleeds and nasal blockage
osteoma – a bony, smooth, non-tender swelling
angiofibroma – a collection of fibrous tissue and blood vessels, typically found in teenage boys, that appears on one side and causes a blocked nose and occasional nose bleeds
Malignant tumours
Malignant tumours are cancerous. They may grow more quickly and can invade surrounding tissues and spread to other parts of the body (metastasis).
Examples of malignant sinonasal tumours:
squamous cell cancer – a common form of skin cancer
lymphoma – tumours of the immune system
melanoma – a type of skin cancer derived from pigmented cells
adenocarcinoma – more common in those people who work with hardwoods
Most sinonasal tumours are benign, but they can also be malignant. It’s important to get any growth looked at by a specialist for an accurate diagnosis and to understand treatment options.
At Welbeck, our ear, nose and throat (ENT) specialists see patients with tumours of the nose in our state-of-the-art Ear, Nose & Throat centre, where they use the most advanced diagnostics and treatment options to provide the best possible care.
More information
The symptoms you experience with a sinonasal tumour can vary depending on the type of tumour and its location.
Symptoms can include:
a persistent, one-sided blocked nose
nosebleeds
nasal discharge or crusting
a decreased sense of smell
a lump
facial pain or numbness
vision problems such as double vision
swollen glands in the neck
Tumours are caused by an abnormal growth of cells or tissues. It’s not always clear what triggers this growth, but there are certain factors that increase the risk of developing a sinonasal tumour.
Risk factors for sinonasal tumours include:
smoking
exposure to dust from wood, leather or textiles
exposure to certain chemicals such as formaldehyde, chromium, and nickel
infection from certain strains of human papillomavirus (HPV)
At your initial consultation, your ENT specialist will talk to you about your symptoms and medical history and will examine your nose. They’ll recommend the most appropriate diagnostic tests to complete your diagnosis.
Diagnostics may include:
nasal endoscopy – a thin, flexible tube with a camera and light is inserted through your nostril to examine your nasal passages and sinuses
a biopsy – where a small tissue sample is removed for further testing
CT, MRI or PET scans
The results of any further testing will be fully explained to you in a follow-up appointment, along with the possible treatment options.
Tumours cannot always be prevented, but there are things you can do to reduce your risk of developing a sinonasal tumour.
Reduce your risk of developing a tumour of the nose by:
avoiding smoking
wearing a well-fitted, protective mask if you work with dust from wood, leather, or textiles
limiting exposure to chemicals such as formaldehyde, chromium, and nickel
Most sinonasal tumours are benign and do not cause many complications.
Complications of tumours of the nose include:
vision problems
problems with speech, swallowing and breathing
numbness in the face
dental problems
If the tumour is malignant, there’s a risk of cancer spreading to other parts of the body.
The treatment options for any sinonasal tumour will depend on its location, size, and whether it’s cancerous or not. Following your diagnosis, your consultant will explain the best treatment options available for you.
Most sinonasal tumours can be removed using surgery. Often this can be done in a minimally invasive procedure through the nose, using an endoscope (a thin, flexible tube with a camera and light attached).
If the tumour is cancerous, your consultant will discuss the next steps with you, including any further treatment needed, such as radiotherapy and chemotherapy.

No, nosebleeds are common and not usually serious. However, persistent, one-sided, or unexplained nosebleeds should be investigated.
It’s rare, but possible, for certain types of benign sinonasal tumours to become cancerous. For example, inverted papillomas are benign but have a 5% to 15% chance of turning into squamous cell carcinoma.
Yes, small tumours can remain asymptomatic until they grow large enough to block airflow, cause facial swelling, or affect surrounding structures.
Yes, it’s possible for sinonasal tumours to return after surgery. Recurrence rates depend on the tumour type and the completeness of surgical removal. Regular follow-ups are recommended after surgery to remove a tumour to monitor your health.
