Salivary Gland Tumors: Early Signs, Risk Factors and Treatment

Have you noticed a small, painless lump near your jaw or ear? Or maybe a swelling in your mouth that doesn’t seem to go away? At first, it may not feel serious. Many people ignore these signs, thinking it’s just a minor issue. But sometimes, these can be early signs of salivary gland tumours.

Salivary gland tumours develop in the glands that produce saliva, the fluid that keeps your mouth moist and helps with digestion. While many of these tumours are not cancerous, some can turn into salivary gland cancer, which needs timely treatment. Understanding the early symptoms, risk factors, and treatment options can help you take the right steps at the right time.

What Are Salivary Gland Tumours?

Salivary gland tumours are abnormal growths that form in your salivary glands. These glands are located in and around your mouth and throat. You have three major pairs of salivary glands:

• Parotid glands (near your ears)
• Submandibular glands (under your jaw)
• Sublingual glands (under your tongue)

There are also many small glands inside your mouth. These tumours can be:

• Benign (non-cancerous) – They grow slowly and usually don’t spread.
• Malignant (cancerous) – They can grow faster and may spread to other parts of the body.

The most common benign salivary gland tumour is called a pleomorphic adenoma. On the other hand, malignant salivary gland tumours are less common but more serious. It’s important to know that not all salivary gland tumours are cancer, but all unusual lumps should be checked by a doctor.

Early Signs and Symptoms of Salivary Gland Tumors

In many cases, the first symptoms of salivary gland cancer are mild and easy to ignore. That’s why awareness is important.

Common early signs include:

• A painless lump near the jaw, ear, or neck
• Swelling in the mouth or face
• A feeling of fullness on one side of the face

These are often the first signs of salivary gland tumours.

Other symptoms may include:

• Numbness in the face
• Weakness or drooping on one side of the face
• Difficulty opening the mouth fully
• Trouble swallowing
• Pain in the face or jaw

These are considered more serious salivary gland cancer symptoms, especially if they persist. In many Indian households, people tend to ignore small lumps or swelling, thinking it’s temporary. But if a lump does not go away within 2–3 weeks, it’s best to consult a Otolaryngologist in Kolkata.

Risk Factors for Salivary Gland Tumors

Doctors don’t always know the exact cause of salivary gland cancer. However, certain factors can increase the risk.

Common risk factors include:

1. Age
   Salivary gland tumours are more common in older adults, but they can occur at any age.
2. Radiation exposure
   People who have had radiation therapy to the head or neck area have a higher risk.
3. Tobacco use
   Smoking or chewing tobacco, which is common in India, may increase the risk.
4. Workplace exposure
   Working in industries involving chemicals, rubber, or metals may increase exposure to harmful substances.
5. Viral infections
   Certain viruses may also play a role, though this is less common.

It’s important to remember that having these risk factors does not mean you will definitely develop salivary gland tumours. It just increases the chances.

How Salivary Gland Tumors Are Diagnosed

If you notice symptoms, a doctor will perform a few tests to find out what’s causing the problem.

Diagnosis usually includes the following:

1. Physical examination
   The doctor will check for lumps or swelling in your face, jaw, and neck.
2. Imaging tests
   Scans help doctors see inside the body. These may include:

• Ultrasound
• CT scan
• MRI

3. Biopsy (FNAC)
   A small sample of cells is taken from the lump using a thin needle. This test helps confirm whether the tumour is benign or malignant. In India, FNAC (Fine Needle Aspiration Cytology) is a commonly used, simple, and affordable test. Early diagnosis plays a key role in successful treatment, especially in cases of salivary gland cancer.

Treatment Options for Salivary Gland Tumors

The treatment depends on:

• Whether the tumor is benign or malignant
• Its size and location
• Whether it has spread

1. Surgery

Surgery is the most common salivary gland tumour treatment.

• For benign tumours, the tumour is removed along with a small part of the gland.
• For cancerous tumours, a larger area may be removed.

Doctors take special care to protect the facial nerves during surgery.

2. Radiation therapy

Radiation uses high-energy rays to destroy cancer cells.

It is often used.

• After surgery to reduce the risk of cancer coming back
• When surgery is not possible

3. Chemotherapy

Chemotherapy uses medicines to kill cancer cells.

It is usually used when:

• The cancer has spread
• Or in advanced cases

4. Targeted therapy (in some cases)

This is a newer treatment that targets specific cancer cells without harming normal cells.

Final Thoughts

Salivary gland tumours may be rare, but they should not be ignored. A painless lump might seem harmless, but it can be an early sign of a bigger problem.

The good news is that with early diagnosis and proper treatment, many people recover well.

If you or someone in your family notices any unusual swelling near the jaw, ear, or mouth, it’s always better to get it checked early. A small step today can prevent bigger problems tomorrow.

FAQs:

Are salivary gland tumours usually cancerous?

No, most salivary gland tumours are benign (non-cancerous), especially those in the parotid gland.

Can a lump near the jaw be a salivary gland tumour?

Yes, a painless lump near the jaw or ear can be a sign of a salivary gland tumour and should be checked by a doctor.

Is surgery always required for salivary gland tumours?

Surgery is the most common treatment, but not all cases require it, especially if the tumour is small or benign.

How long does it take for a salivary gland tumour to grow?

It depends on the type—benign tumours usually grow slowly over years, while malignant ones may grow faster.

Can salivary gland tumours recur after treatment?

Yes, some tumours can come back after treatment, so regular follow-up with your doctor is important.

Can imaging tests detect salivary gland tumours early?

Yes, imaging tests like ultrasound, CT scan, or MRI can help detect tumours early and guide diagnosis.
