Minor salivary gland tumours of the palate: what surgery involves | CION Cancer Clinics
A minor salivary gland tumour of the palate is a lump growing from one of the many tiny saliva glands in the roof of the mouth. Some are not cancer and some are. Surgery removes the lump with a rim of healthy tissue around it, usually through the mouth. If bone is involved, part of the palate comes out too, and the gap is closed with a dental plate or with tissue. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is a minor salivary gland tumour of the palate?
It is a growth that starts in one of the tiny saliva glands lining the roof of your mouth. You have hundreds of these small glands spread through the lining of the mouth and throat, and the palate has more of them than most places. That is why the roof of the mouth is the most common site for these tumours.
How it usually shows itself
Most people notice a firm, smooth swelling on one side of the roof of the mouth, often towards the back. It frequently does not hurt, which is why it may be found by a dentist or when a denture stops fitting. Pain, numbness, bleeding, an ulcer or loose teeth nearby are more worrying and should be checked promptly.
Who can be affected
These tumours occur across adult life, including in people who have never smoked or chewed tobacco. That sets them apart from the more common mouth cancers linked to tobacco. A lump in the palate should be checked whatever your habits.
What it might be
Is it cancer, and what types are there?
Only a biopsy can say. In these tiny glands a larger share of tumours are cancers than in the big saliva glands, so every palate lump is taken seriously.
Pleomorphic adenoma
The most common tumour here that is not cancer. It grows slowly and does not spread, but it is removed because it keeps growing and can, rarely, change into a cancer over many years.
Mucoepidermoid carcinoma
One of the more common salivary cancers. Low-grade types grow slowly and behave gently. High-grade types grow faster and may need more treatment after surgery.
Adenoid cystic carcinoma
A cancer that tends to grow slowly but spreads along nerves, sometimes further than the lump suggests. Scans look for this, and radiotherapy is often discussed after surgery.
Other types
Polymorphous adenocarcinoma and several rarer cancers can also start here. The pathology report names the exact type, and the type shapes the plan more than the size alone.
Not sure whether this applies to you?
Ask an oncologistBefore surgery
How does a palate lump go from first check to a plan?
Examination and biopsy
A specialist looks at the lump and feels the neck for lymph nodes. A small piece of tissue is taken, usually under local anaesthetic, to find out what the lump is.
Scans
A CT scan shows whether the bone of the palate is thinned or worn away. An MRI shows soft tissue and whether the tumour is tracking along a nerve. Often both are needed.
Tumour board
Surgeons, radiation oncologists, radiologists and pathologists look at the results together. A dental specialist who makes plates for the mouth may join if bone removal is likely.
The plan is explained
You hear what will be removed, how any gap will be closed, and whether further treatment is expected. Bring a family member and your questions.
The operation
What does palate surgery remove?
The surgeon removes the tumour with a margin, a rim of normal tissue around it, to lower the chance of it coming back. How much comes out depends on the size of the tumour, its type and whether it has reached the bone.
When the lump sits only in the lining
If the bone is not involved, the tumour and the lining over it are removed through the mouth, with no cut on the face. The bone beneath is often left in place. The raw area heals over several weeks, sometimes under a protective plate.
When bone has to be removed
If the tumour has worn into the bone, part of the hard palate is taken out. This is called a partial maxillectomy, meaning removal of part of the upper jaw. It leaves an opening between the mouth and the nose, which has to be closed so you can eat and speak normally.
Who a bigger operation may not suit
For some people, general health or the spread of the disease means a large operation carries more harm than benefit. The team weighs this with you. Radiotherapy or other approaches may then be discussed instead.

Side by side
How is a gap in the palate closed?
A dental plate (obturator)
Tissue repair (flap)
A custom plate that fits against the opening, made by a dental specialist
Tissue moved from nearby, or from elsewhere in the body, to seal the opening
Lets the team look directly at the area at check-ups
The opening is sealed, so there is nothing to take out or clean
Needs refitting as the area heals and changes shape
A longer operation, sometimes with a second wound where tissue was taken
Often used for smaller and medium gaps
Often used for larger gaps, or where a plate will not hold
Commonly believed
What do families often believe about a palate lump?
"It does not hurt, so it cannot be serious."
Many cancers of the palate cause no pain for a long time. A lump that does not hurt still needs a biopsy. Waiting for pain to appear can mean waiting until the tumour has grown into the bone.
"I never smoked, so it cannot be cancer."
Tumours of the tiny saliva glands are not strongly linked to tobacco. They occur in people who have never smoked or chewed. Your habits do not rule a cancer in or out.
"Losing part of the palate means I will never eat or speak normally again."
A well-fitted plate or a tissue repair usually lets people eat, drink and speak clearly again. It takes practice and some adjustment in the first months. A speech therapist and a dental specialist help with this.
"A biopsy will make the tumour spread."
A biopsy is how the type of tumour is found, and the type decides the operation. It does not send cancer through the body. Skipping it leaves the team planning without the most important fact.
On your report
What words will you see on the report?
- Minor salivary gland
- One of the tiny saliva glands in the lining of the mouth and throat, as opposed to the large glands in the cheek and under the jaw.
- Hard and soft palate
- The bony front part of the roof of the mouth, and the soft, muscular part behind it.
- Perineural invasion
- Cancer cells seen growing along or around a nerve. It often leads the team to discuss radiotherapy.
- Grade
- How abnormal the cells look under the microscope. Low grade usually means slower growing.
- Margin
- The rim of normal tissue around what was removed. Clear means no cancer cells were seen at the edge.
- Obturator
- A removable dental plate that closes an opening in the palate.
Questions we are asked
Common questions about palate tumour surgery
Is a lump on the roof of my mouth always cancer?
No. Many lumps on the palate are not cancer, and some are not tumours at all, such as a bony bump or an infection from a tooth. But in the tiny saliva glands a sizeable share of tumours are cancers, so any lump that does not settle within a couple of weeks should be checked by a specialist.
Can the tumour be removed through the mouth?
Usually, yes. Most palate tumours are removed through the open mouth without any cut on the face. Very large tumours, or those reaching into the nose or sinus, may need a different approach. Your surgeon will explain the route once the scans have been reviewed.
Will I have a hole in the roof of my mouth?
Only if bone has to be removed. Then there will be an opening between the mouth and the nose, closed with a dental plate or with tissue. Without closure, food and drink can pass into the nose and speech sounds nasal, which is why the closure is planned before the operation.
When will I be able to eat normally?
Soft and liquid foods come first, usually for the early weeks while the area heals. People with a plate learn to eat with it gradually. Most return to a wide range of foods, though very hard or sticky foods may stay difficult. A dietitian can help you keep your weight up.
Will I need radiotherapy after surgery?
It depends on the type and grade of the cancer, the margins and whether nerves were involved. Radiotherapy is often discussed for adenoid cystic carcinoma and for high-grade cancers. It is usually not needed for a tumour that is not cancer and was removed completely. The tumour board recommends once the report is ready.
Can it come back?
Yes, some can, sometimes many years later. That is why follow-up visits continue for a long time, and why the surgeon aims for a clear margin. A tumour that is not cancer and was removed in one piece seldom returns. Your team will tell you how often you need checks.
Will my teeth be affected?
If part of the upper jaw is removed, some teeth on that side may come out with it. The dental plate can carry replacement teeth. A dental check before surgery is useful, because infected teeth are easier to treat before the operation and any radiotherapy than after.
Does Aarogyasri or insurance cover this surgery?
Often, yes, when it is part of cancer treatment. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. The dental plate may be covered differently from the operation, so ask about it separately. Call the helpline with your card details and the team will check your cover.
