What are head and neck lumps?

Head and neck lumps are abnormal swellings or masses that can develop in various areas of the head and neck region, including the scalp, face, throat, neck, and even inside the mouth or nose. These lumps can vary significantly in size, shape, and consistency, and their causes range from benign (non-cancerous) to malignant (cancerous) conditions.

It’s important to seek professional medical advice to determine the underlying cause of a head or neck lump and to receive appropriate treatment if necessary. Early diagnosis can significantly improve outcomes, particularly in cases where the lump is malignant (cancerous).

An enlarged lump in the neck can indicate swollen lymph nodes, which may be caused by infections, inflammation, or more serious conditions like cancer.

What causes a lump in the head and neck region?

Lumps in the head and neck region can be caused by a variety of factors, ranging from benign conditions to more serious underlying diseases. Understanding the possible causes is essential for accurate diagnosis and treatment. Here are some of the most common causes:

Infections: infections are one of the primary causes of lumps in the head and neck area. These can lead to the enlargement of lymph nodes, commonly known as swollen glands.
- Viral infections: conditions like the common cold, influenza, and infectious mononucleosis can cause lymph nodes to swell as the body fights off the infection.
- Bacterial infections: bacterial infections, such as strep throat or dental abscesses, can also result in swollen lymph nodes. In some cases, these infections can form abscesses, which are pockets of pus that feel like lumps.
- Tuberculosis and HIV: more serious infections like tuberculosis or HIV can also present with enlarged lymph nodes in the head and neck region.
Cysts: cysts are non-cancerous, fluid-filled sacs that can develop in the head and neck. They are usually harmless but can cause discomfort if they become infected or grow large.
- Sebaceous cysts: these are commonly found on the scalp or face and are caused by blocked sebaceous glands.
- Thyroglossal duct cysts: these cysts form along the pathway that the thyroid gland follows during development in the embryo. They often present as a midline neck lump.
- Branchial cleft cysts: these congenital cysts are remnants of embryonic development and are typically found on the side of the neck.
- Dermoid cysts: these are rare congenital cysts that can contain hair, skin, and other tissues and are usually found in the head or neck.
Benign tumours: benign tumours are non-cancerous growths that can cause lumps in the head and neck region. They generally grow slowly and do not spread to other parts of the body.
- Lipomas: these are soft, fatty tumours that can occur under the skin anywhere in the head and neck region.
- Fibromas: these are tumours composed of fibrous or connective tissue and can develop in various locations in the head and neck.
- Hemangiomas: these benign growths of blood vessels are often present at birth and can appear as lumps on the head or neck.

Malignant tumours: malignant or cancerous tumours in the head and neck region are less common but require immediate attention due to their serious nature.
- Thyroid cancer: nodules in the thyroid gland can sometimes be cancerous, leading to a lump in the front of the neck.
- Skin cancers: malignant skin tumours like melanoma or squamous cell carcinoma can develop as lumps on the scalp, face, or neck.
- Lymphomas: these cancers of the lymphatic system can present as painless lumps in the head and neck.
- Salivary gland tumours: tumours in the salivary glands, such as parotid gland tumours, can cause noticeable lumps. Some of these tumours can be malignant.
Trauma: injury or trauma to the head or neck can result in the formation of a lump.
- Hematomas: these are collections of blood outside the blood vessels, usually caused by injury. They may appear as a painful, swollen lump.
- Fractures: severe trauma that results in fractures to the facial bones can also lead to swelling and lump formation.
Thyroid nodules: most thyroid nodules are benign, but a small percentage may be cancerous. They can cause a visible lump and sometimes lead to symptoms like hoarseness or difficulty swallowing.

Understanding the underlying cause of a lump in the head and neck region is crucial for determining the appropriate treatment plan. If you notice a persistent or concerning lump, it’s important to consult a healthcare professional for an accurate diagnosis and timely management.

Sometimes, issues with the thyroid gland, such as nodules or goitre, can cause a noticeable lump in the neck.

What are the symptoms of a lump in the head and neck region?

The symptoms associated with a lump in the head and neck region can vary widely depending on the underlying cause. Some lumps may be asymptomatic and discovered incidentally, while others may present with noticeable discomfort or other associated symptoms. Here’s a breakdown of common symptoms to be aware of:

Physical characteristics of the lump

- - Size and shape: lumps can range from very small (pea-sized) to large, and they can be round, oval, or irregular in shape.
  - Consistency: the lump may feel soft, rubbery, firm, or hard to the touch. Some lumps, like cysts, may be fluid-filled and feel spongy, while others, like tumours, may feel solid.
  - Mobility: some lumps can be easily moved under the skin, while others are fixed and immobile. A lump that is hard and immovable may be more concerning.
  - Tenderness: lumps caused by infections or inflammation are often tender or painful to touch, whereas benign or malignant tumours may be painless.

Pain

- - Localised pain: a lump may cause localised pain at the site, especially if it’s associated with an infection, abscess, or inflamed lymph node.
  - Referred pain: sometimes, the pain from a lump may radiate to nearby areas, such as the ear, jaw, or shoulder, particularly if the lump is pressing on a nerve or muscle.

Swelling and inflammation

- - Redness and warmth: lumps caused by infections or abscesses may be accompanied by redness, warmth, and swelling of the surrounding tissue.
  - Visible swelling: some lumps, especially those on the neck or face, can cause visible swelling that may alter the appearance of the affected area.

Systemic symptoms

- - Fever: a fever may accompany a lump if it is due to an infection, such as with swollen lymph nodes or an abscess.
  - Fatigue: generalised fatigue and malaise may be present, particularly if the lump is related to a systemic infection or a malignancy.

Difficulty swallowing (Dysphagia)

- Swallowing issues: a lump in the neck, particularly near the throat or oesophagus, may cause difficulty swallowing or a sensation of something being stuck in the throat.
- Hoarseness: if the lump is near the vocal cords or larynx, it may cause changes in voice, including hoarseness or a raspy quality.
Changes in the skin overlying the lump: the skin over the lump may become discoloured, turning red, purple, or blue, particularly if there’s bleeding, infection, or a vascular issue. In some cases, the skin over a malignant lump may break down, leading to ulceration or open sores.
Swollen lymph nodes: enlarged lymph nodes in the neck, under the jaw, or near the collarbone are common and can be associated with infections, autoimmune conditions, or malignancies.

Is a lump in the head and neck region always painful?

A lump in the head and neck region is not always painful. The presence or absence of pain often depends on the underlying cause of the lump. For example, lumps caused by infections, such as swollen lymph nodes, abscesses, or inflamed cysts, tend to be tender and painful due to the body’s immune response.

On the other hand, benign tumours, cysts, and even some malignant tumours can develop without causing any pain, which makes them harder to detect until they grow larger or start to interfere with nearby structures. In some cases, the lack of pain might lead individuals to delay seeking medical evaluation, which can be concerning, particularly if the lump is associated with a more serious condition. Therefore, it’s important to pay attention to other accompanying symptoms, such as changes in size, shape, or texture, and seek medical advice even if the lump is painless.

Pain can sometimes be a symptom of a lump, especially if it's due to an infection or inflammation.

Who is at risk of developing a lump in the head and neck region in Singapore?

In Singapore, several factors can increase the risk of developing a lump in the head and neck region. These risk factors are often related to lifestyle choices, environmental exposures, and underlying health conditions. Here are some key groups that may be at higher risk:

Smokers and tobacco users: individuals who smoke or use tobacco products are at a significantly higher risk of developing lumps in the head and neck region, particularly those associated with cancer. Tobacco use is a major risk factor for cancers of the oral cavity, throat, larynx, and other areas of the head and neck. Even smokeless tobacco products, like chewing tobacco, increase the risk of developing tumours in these regions.
Heavy alcohol consumers: excessive alcohol consumption is another major risk factor for head and neck cancers. The combined effect of smoking and heavy drinking further amplifies this risk, making these individuals particularly vulnerable to developing malignant lumps in the head and neck area.
Elderly individuals: as people age, the likelihood of developing lumps, both benign and malignant, increases. This is partly due to the natural aging process and the cumulative exposure to risk factors over time. Elderly individuals should be vigilant about any new lumps, as the risk of malignancy is higher in this age group.
Individuals with a history of viral infections: certain viral infections, such as the Human Papillomavirus (HPV) and the Epstein-Barr Virus (EBV), have been linked to an increased risk of developing head and neck cancers. In particular, HPV-related oropharyngeal cancers have been on the rise globally, including in Singapore. People with a history of these viral infections may be at higher risk of developing related lumps.
People with a family history of cancer: a family history of head and neck cancers or other cancers can increase an individual’s risk of developing similar conditions. Genetic predisposition may play a role in the likelihood of developing both benign and malignant lumps in the head and neck region.
Individuals with chronic infections or immune system disorders: chronic infections, such as tuberculosis or HIV, and immune system disorders can lead to persistent swelling of lymph nodes in the head and neck, presenting as lumps. These individuals are at higher risk of developing such lumps and should be closely monitored.
Patients with previous head and neck cancer: individuals who have previously been treated for head and neck cancer are at an increased risk of developing new lumps in the same region, whether due to recurrence or the development of a new primary tumour. Regular follow-up and monitoring are crucial for these patients.

Understanding these risk factors can help individuals take proactive steps to monitor their health and seek early medical attention if they notice any unusual lumps in the head and neck region. Early detection and intervention are key to effective treatment and better outcomes.

How are lumps in the head and neck region diagnosed for further evaluation?

At NC Tan Surgery, we diagnose lumps in the head and neck region using a combination of clinical examination and various diagnostic tests to determine the underlying cause and nature of the lump. Here’s an overview of the diagnostic process we employ:

Medical history and physical examination: our diagnostic process begins with a thorough medical history and physical examination. Our doctor will ask about the lump’s duration, any associated symptoms (such as pain, difficulty swallowing, or weight loss), and any relevant personal or family history, such as smoking, alcohol use, or previous cancers. During the physical examination, the doctor will assess the size, location, consistency, and mobility of the lump.
Imaging studies: may be necessary to obtain a more detailed view of the lump and the surrounding tissues. Types of imaging tests may include;
- Ultrasound: an ultrasound is commonly used as an initial imaging study, particularly for lumps in the neck. It can help determine whether a lump is solid or cystic (fluid-filled) and assess its size and vascularity.
- CT scan (Computed Tomography): a CT scan provides cross-sectional images of the head and neck, which helps with a more detailed assessment of the lump’s location and its relationship to nearby structures. This imaging modality is especially recommended for evaluating deep-seated lumps.
- MRI (Magnetic Resonance Imaging): MRI is another imaging option that provides high-resolution images of soft tissues. It is particularly useful for evaluating lumps that are suspected to involve nerves, muscles, or other soft tissues.
- PET Scan (Positron Emission Tomography): a PET scan may be used if there is a suspicion of cancer. It helps identify areas of high metabolic activity, which could indicate the presence of malignant cells.
Biopsy: in some cases, a biopsy may be required to definitively diagnose the nature of a lump, especially if there is concern about cancer.
- Fine needle aspiration (FNA): FNA is a minimally invasive procedure where a thin needle is used to extract cells from the lump for microscopic examination. It is commonly used for lumps in the lymph nodes, thyroid, and salivary glands.
- Core needle biopsy: this procedure uses a larger needle to obtain a tissue sample from the lump. It provides more tissue than FNA, allowing for a more comprehensive analysis.
- Excisional biopsy: in some cases, the entire lump may be surgically removed (excisional biopsy) for histopathological examination. This is often done if the lump is small, easily accessible, and there is a need for a definitive diagnosis.
Laboratory tests: laboratory tests may be performed to support the diagnosis, particularly if the lump is related to an infection, autoimmune condition, or cancer.
- Blood tests: blood tests can provide information about infection, inflammation, or tumour markers that may be relevant to the lump's cause.
- Thyroid function tests: if the lump is related to the thyroid gland, thyroid function tests may be performed to assess hormone levels and gland activity.
Endoscopy: in cases where the lump is located in areas such as the throat, nasal passages, or larynx, an endoscopy may be required. During this procedure, a thin, flexible tube with a camera is inserted to visualise the internal structures and obtain biopsies if necessary.
Cytology and histopathology: cells or tissues obtained from the biopsy will be sent to a laboratory for cytological or histopathological analysis. Pathologists will examine the samples under a microscope to identify the type of cells present and determine whether the lump is benign or malignant.

This comprehensive diagnostic approach ensures that the underlying cause of the head and neck lump is accurately identified, which can help guide appropriate treatment and management.

What are the common treatment options for the lumps in the head and neck region?

The treatment options for lumps in the head and neck region depend on the underlying cause, the location and size of the lump, and the overall health of the patient. At NC Tan Surgery, we employ the following treatment options for the lumps in the head and neck region:

- Observation and monitoring: in cases where the lump is small, asymptomatic, and likely benign, doctors may recommend a watch-and-wait approach. This involves regular monitoring and follow-up appointments to observe any changes in the lump’s size, shape, or associated symptoms. If the lump remains stable and non-problematic, no further treatment may be necessary.

Medications

- Antibiotics: if the lump is caused by a bacterial infection, such as an infected lymph node or abscess, antibiotics may be prescribed to eliminate the infection. Once the infection is resolved, the lump often decreases in size or disappears entirely.
- Antiviral medications: for lumps associated with viral infections, such as those caused by the Epstein-Barr virus (related to mononucleosis) or herpes, antiviral medications may be recommended.
- Anti-inflammatory drugs: non-steroidal anti-inflammatory drugs (NSAIDs) or corticosteroids may be prescribed to reduce inflammation and pain associated with certain types of lumps, such as those caused by autoimmune conditions or inflammatory disorders.
Surgical removal: surgery is often the treatment of choice for lumps that are suspicious for malignancy, cause significant discomfort, or interfere with normal functions such as swallowing or breathing.
- Excisional biopsy: in some cases, the entire lump is surgically removed not only for diagnostic purposes but also to eliminate the abnormal tissue.
- Tumour resection: if the lump is found to be malignant, a more extensive surgery may be required to remove the tumour along with some surrounding healthy tissue to ensure complete excision.
- Cyst removal: benign cysts, especially those that are large, recurrent, or symptomatic, may be surgically removed to prevent complications like infection or rupture.
- Thyroidectomy: if the lump is a thyroid nodule and is found to be cancerous or causing other health issues, partial or total removal of the thyroid gland (thyroidectomy) may be necessary.

The choice of treatment is highly individualised and depends on the specific diagnosis, the patient's overall health, and personal preferences. If you suspect a lump in your head or neck, schedule a consultation with NC Tan Surgery for expert evaluation and personalised care.

In cases where a neck lump is caused by thyroid nodules, goitre, or thyroid cancer, thyroidectomy may be necessary to remove part or all of the thyroid gland.
