An Asian woman uses her fingers to touch under the jaw and along the side of the neck, self-checking the neck lymph nodes for swelling or tenderness.

The lymphatic system plays an important role in maintaining fluid balance by collecting excess tissue fluid, while lymph nodes throughout the body help filter and eliminate pathogens and viruses. It serves as a key defence system that supports overall health and immunity¹. However, when lymphocytes undergo malignant changes, lymphoma may develop. As early lymphoma symptoms can resemble common colds or inflammation², many people may overlook the warning signs. How can we identify possible abnormalities in the lymphatic system at an early stage?

With advances in medical technology, targeted therapy and immunotherapy have provided new treatment options for patients, but the associated medical expenses should also be carefully considered. This article explores common lymphoma symptoms, treatment approaches and long-term financial protection considerations.

Understanding Lymphoma: The "Silent Threat" Hidden Within the Immune System

Lymphoma is not a single disease, but a general term for malignant tumours that originate from the lymphatic system. Generally, lymphoma is divided into two major types: "Hodgkin lymphoma" and "non-Hodgkin lymphoma"³. Among these, non-Hodgkin lymphoma is more commonly seen in Asian populations.

According to cancer statistics from the Hong Kong Hospital Authority Cancer Registry, lymphoma has consistently ranked among the top ten most common cancers in Hong Kong⁴. In 2023, it accounted for 3.3% of all newly diagnosed cancer cases. Lymphoma can affect people across different age groups. Although there is no single confirmed cause, it is generally believed to be associated with factors such as immune system dysfunction, viral infections (such as Epstein-Barr virus) and genetic mutations⁵.

Suspecting Lymphoma Symptoms? Recognising Warning Signs from Your Body

The Most Common Warning Sign: Painless Swollen Lymph Nodes⁵

Lymph nodes are distributed throughout the body. When lymphoma develops, one of the most typical early lymphoma symptoms is the appearance of painless lumps in areas such as the neck, armpits or groin⁵. Unlike swollen lymph nodes caused by ordinary inflammation or infection, lymphoma-related lumps are usually firmer in texture and do not cause significant pain when pressed. As a result, they may be easily overlooked.

Important Body Signals: Common Symptoms of Non-Hodgkin Lymphoma⁵

Apart from localised lumps, lymphoma may also cause a group of systemic symptoms known as "B symptoms"⁵. Individuals should pay particular attention if they experience the following:

Persistent fever: An unexplained rise in body temperature that is not caused by a common infection.
Night sweats: Excessive sweating during sleep, sometimes severe enough to require changing clothes.
Unexplained weight loss: A loss of more than 10% of body weight within six months without dieting or increasing physical activity.
Persistent itchy skin: Some patients may experience generalised itching that is difficult to relieve.

If these symptoms are mistaken for fatigue caused by work stress or a common cold, diagnosis and treatment may be delayed. Therefore, if these symptoms persist for more than two weeks, it is recommended to seek professional medical advice as soon as possible. A common diagnostic procedure for lymphoma is a lymph node biopsy, which involves removing or sampling an enlarged lymph node and examining the cells under a microscope⁶.

Diagnosis Process and Latest Treatment Trends for Lymphoma

From Initial Assessment to Accurate Diagnosis

If lymphoma is confirmed, modern medicine generally uses the following approaches to evaluate the condition and determine the extent of disease⁷.

Blood tests: Blood tests may examine red blood cells, white blood cells and platelets. Doctors may also assess liver function, kidney function, electrolyte levels, lactate dehydrogenase (LDH), uric acid levels and possible viral infections.
Imaging examinations (such as PET/CT scan): Positron emission tomography-computed tomography (PET/CT) helps identify the location and extent of cancer cell spread in the body and assists doctors in determining the cancer stage.
Bone marrow examination: A bone marrow sample may be examined to determine whether lymphoma cells have spread to the bone marrow system.

Modern Medical Advances: Targeted Therapy and Immunotherapy

Although traditional chemotherapy can be effective in treating lymphoma, it may also affect normal cells during treatment. In recent years, advances in therapies targeting specific cancer markers, such as the CD20 antigen found on B cells, have led to significant progress in lymphoma treatment⁷.

Monoclonal antibody therapy: These medicines can precisely recognise and bind to cancer cells, helping the immune system identify and destroy tumour cells while reducing damage to surrounding normal cells.
Radioimmunotherapy: This treatment combines radioactive isotopes with antibodies to deliver radiation directly to cancer cells for targeted destruction⁸.
New-generation medications: New-generation medicines such as bendamustine, when used together with anti-CD20 monoclonal antibodies, are mainly used for certain low-grade or indolent B-cell lymphomas and lymphoproliferative disorders. This combination may also be better tolerated by some older patients and can provide additional treatment options.

Managing Medical Expenses: Planning Long-Term Protection Arrangements

Lymphoma is not necessarily an incurable disease. With early detection and appropriate treatment, patients may have a relatively higher chance of achieving remission or recovery⁹. However, if private healthcare services are selected, certain cancer treatments, such as radiotherapy, may involve significant expenses. Actual costs may vary depending on treatment methods, number of treatment sessions and individual circumstances¹⁰.

To address potential protection gaps, individuals may consider the following protection arrangements based on their personal needs and budget:

Medical insurance plans or Voluntary Health Insurance Scheme (VHIS): These plans generally provide reimbursement-based coverage, meaning eligible medical expenses are reimbursed according to the actual costs incurred. Some comprehensive medical insurance plans may provide higher coverage limits for eligible cancer treatments, including chemotherapy, radiotherapy, targeted therapy and immunotherapy. Actual coverage, reimbursement arrangements and other policy terms vary depending on the individual insurance plan.
Critical illness insurance plans: Unlike medical insurance, critical illness insurance provides a lump-sum cash benefit when the insured person is diagnosed with a specified serious illness. The payout may be used according to personal needs, such as supplementing medical expenses, covering daily living costs or managing other financial arrangements. Some plans may also provide multiple-claims benefits¹¹, subject to individual policy terms and conditions.

FAQs About Lymphoma

Not necessarily. The most common causes of swollen lymph nodes are infections or inflammation, such as tooth infections or tonsillitis. These lumps are often accompanied by symptoms such as redness, swelling, warmth and tenderness, and usually disappear once the underlying condition improves. However, if a lump is painless and persists without reducing in size, it is recommended to seek professional medical advice for further assessment.

Lymphoma itself is not an infectious disease and cannot be transmitted through daily contact with others. Although lymphoma is not directly considered a hereditary disease, individuals with a family history of lymphoma may have a relatively higher risk. In addition, certain viral infections, such as Helicobacter pylori and Epstein-Barr virus (EBV), may increase the risk of developing specific types of lymphoma.⁸

The prognosis of lymphoma varies depending on the lymphoma subtype, disease stage, and the patient's overall health. Generally, early-stage Hodgkin lymphoma may have a cure rate of up to 80% to 90%⁵. Even for advanced-stage or more aggressive types of non-Hodgkin lymphoma, advances in targeted therapy and immunotherapy have significantly improved survival outcomes and treatment possibilities^8,9.

Treatment plans for lymphoma vary depending on factors such as the lymphoma subtype, disease stage and the patient's individual condition. Related medical expenses may also differ according to treatment methods, treatment schedules and healthcare providers. Medical insurance plans may generally provide coverage for eligible medical expenses that meet the policy terms, including certain cancer-related treatment costs. This may help reduce the financial burden during treatment. Actual coverage scope, reimbursement arrangements and exclusions depend on the terms and conditions of individual insurance policies.
