95% of Adults Have Epstein-Barr Virus: How it Increases Your Risk of Cancer

As a busy professional, you know that your health and longevity depend on staying informed and proactively managing risks. One stealth threat that often goes undetected is the Epstein-Barr virus (EBV).

EBV is a common virus in the herpes virus family that infects up to 95% of adults worldwide at some point in their lives. For most, EBV causes no symptoms or only a mild illness. However, EBV infection is also associated with several severe diseases later in life, including cancer.

By understanding EBV, how it relates to your health, and the steps you can take now, you gain valuable knowledge and an action plan to support your wellbeing and longevity.

TLDR: EBV is linked to various cancers, such as nasopharyngeal carcinoma and lymphomas.

• EBV is a common virus that infects up to 95% of adults.
• While EBV usually causes mild or no symptoms, it can lead to serious diseases and cancer later in life.
• Understanding EBV and taking proactive steps can help support your health and longevity.

What Is Epstein-Barr Virus (EBV)?

Epstein-Barr virus (EBV) is a member of the herpesvirus family that infects humans. EBV is one of the most common human viruses, infecting nearly all adults worldwide.

How Does it Spread?

The virus spreads primarily through saliva and is usually transmitted through close personal contact, such as kissing.

What Are The Symptoms?

Infection with EBV typically occurs during childhood or adolescence and causes few or no symptoms. However, in some cases EBV leads to infectious mononucleosis, also known as mono or the “kissing disease" - characterized by fever, sore throat, fatigue and swollen lymph nodes in the neck.

What Happens After Infection?

Once infected with EBV, the virus remains dormant or inactive in certain white blood cells in the body for life. Periodic reactivation of the virus may occur, but typically causes no symptoms in healthy individuals. However, reactivation of EBV in immunocompromised persons can lead to serious complications. EBV infection has also been linked to several types of cancer, including Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma.

Prevalence and Transmission

EBV spreads through contact with saliva and respiratory droplets. By adulthood, over 95% of people have been infected with EBV at some point in their lives.

The Link Between EBV and Cancer

The Epstein-Barr virus (EBV) has been linked to several types of cancer.

Nasopharyngeal Carcinoma

EBV infection is a causative factor in nasopharyngeal carcinoma, a cancer of the upper throat (the most common head and neck cancer in Singapore).

Lymphoma

EBV is associated with certain lymphomas and lymphoproliferative disorders. Infection with EBV early in life increases the risk of Burkitt's lymphoma.

EBV is also strongly linked to Hodgkin's lymphoma, with the virus detected in tumor cells of up to 50% of cases in developed nations.

How Does it Happen?

The mechanisms by which EBV may promote oncogenesis are complex. The virus may directly transform B lymphocytes through expression of viral oncoproteins like latent membrane protein 1 (LMP1). EBV infection can also lead to genomic instability and indirectly contribute to cancer development over many years of latency and reactivation.

Interpreting EBV Antibody Test Results

Interpreting the results of your EBV antibody test is important for understanding your risk of EBV-related illnesses. There are three main antibodies tested:

VCA IgG

Viral Capsid Antigen IgG antibodies develop early after EBV infection and remain elevated for life. A positive result indicates past EBV exposure, but not necessarily a current active infection. Around 95% of adults will test positive for VCA IgG.

VCA IgM

Viral Capsid Antigen IgM antibodies are produced temporarily during early EBV infection. A positive VCA IgM test means there is likely a current or very recent EBV infection. VCA IgM levels decline a few months after infection. A negative VCA IgM test in the presence of a positive VCA IgG test indicates past EBV exposure without a current active infection.

EBNA IgG

Epstein-Barr Nuclear Antigen IgG antibodies develop several months after EBV infection and also remain positive for life. A positive EBNA IgG test, along with a positive VCA IgG and negative VCA IgM, means there was an EBV infection in the past, but no current active infection.

EBV Antibody Testing: Who Should Be Screened?

Who Should Be Tested

Those who should consider EBV antibody testing include:

1. Healthy adults over age 35. As we age, the risk of EBV-related complications and certain EBV-associated cancers increases. EBV antibody testing at age 35 and older, even without symptoms, may help establish a baseline and monitor for significant changes over time.
2. Adolescents and young adults with symptoms of mononucleosis such as fatigue, sore throat, swollen lymph nodes, and fever. EBV antibody testing can confirm the diagnosis of mononucleosis and rule out other potential causes.
3. Patients with chronic fatigue or fibromyalgia. Some research links EBV infection to chronic fatigue syndrome and fibromyalgia. EBV antibody testing may provide information to better understand a patient’s condition and treatment options.
4. Patients with compromised or weakened immune systems. For those with HIV/AIDS, organ transplants, or autoimmune disease, EBV infection or reactivation can lead to serious complications. Routine EBV antibody testing may help monitor for infection or changes in antibody levels.

EBV antibody testing, along with a comprehensive physical exam and evaluation of risk factors, can determine who may benefit from more frequent EBV screening and monitoring.

Lifestyle Factors That Impact EBV and Cancer Risk

To reduce your risk of EBV-related cancers, focus on lifestyle factors under your control.

Limit Alcohol Consumption

Excessive alcohol use can weaken your immune system and increase the risk of EBV-related cancers. Limit intake to no more than one drink per day for women, and two per day for men. Abstaining from alcohol altogether may provide the greatest benefit.

Maintain a Healthy Weight

Carrying excess weight puts extra stress on your body and immune system. Losing weight through diet and exercise can help reduce inflammation in the body. Aim for a balanced diet low in sugar, refined carbs, and processed foods. Focus on lean proteins, healthy fats like olive oil, and fiber-rich whole grains, fruits and vegetables.

Get Adequate Sleep

Lack of sleep can negatively impact your immune function. Most adults need 7 to 9 hours of sleep per night to feel well-rested. Make sleep a priority and stick to a consistent sleep schedule, even on weekends. Keep your bedroom cool, dark, and quiet for the best quality rest.

Manage Stress Levels

Chronic stress releases hormones like cortisol that can suppress your immune system, allowing EBV to become active or reactivate. Try relaxation techniques like yoga, meditation, deep breathing, or journaling. Spending time in nature and exercising regularly also help lower stress. Seek professional counseling or therapy if needed.

Don't Smoke or Vape

Tobacco use is a major risk factor for EBV-related cancers like nasopharyngeal carcinoma and Hodgkin's lymphoma. Quitting smoking or vaping is one of the best things you can do for your health and EBV management. Talk to your doctor about medications or nicotine replacement options that can help you stop for good.

Nutritional Strategies to Manage EBV

To help manage EBV-related cancers, several nutritional strategies can be employed. These include:

Reducing Salt Intake

Excessive salt intake has been linked to an increased risk of nasopharyngeal carcinoma (NPC), a type of EBV-related cancer. Salt consumption can raise inflammation and stimulate the growth and spread of cancer cells.

To help lower NPC risk:

• Choose fresh produce, meats and whole grains. Season yourself with herbs and spices instead of pre-seasoned foods.
• Check nutrition labels for lower sodium content. Aim for 2,300 mg of sodium per day or less. Use salt alternatives for flavor.
• Request sauces and dressings on the side. Ask for "less salt" when eating out.
• Over time, your taste buds adjust to less salt. Reducing sodium by 500 to 1,000 mg daily can lower health risks.

Adequate Protein Intake

Consuming adequate amounts of high-quality protein provides the amino acids necessary for immune health.

Aim for 20 to 30 grams of protein with each meal, especially at breakfast. Good sources include organic chicken, grass-fed beef, fatty fish like salmon, eggs, nuts, and legumes.

Reduce Sugar and Refined Carbohydrates

Sugar and refined carbs like white flour promote inflammation in the body and EBV-related cancers. Limit intake of sweets, sugary beverages, white bread, and pasta.

Instead, choose complex carbs from vegetables, fruits, whole grains. Aim for less than 25 grams or about 6 teaspoons of added sugar per day.

Increase Certain Nutrients

Several nutrients help support immune health and inhibit EBV, including:

• Zinc: Found in oysters, beef, pumpkin seeds. Aim for 15 mg per day.
• Selenium: Found in Brazil nuts, sardines, eggs. Aim for 55 mcg per day.
• Vitamin D: Fatty fish, egg yolks, fortified foods. Aim for 600 to 800 IU per day.
• Turmeric or Curcumin: Turmeric spice or curcumin supplements have antiviral and anti-inflammatory effects. Aim for 500 to 1000 mg of curcumin 2-3 times per day.

Stay Hydrated

Drinking plenty of water and herbal tea helps flush out toxins from your cells and provides moisture for mucous membranes. Aim for 6 to 8 glasses of filtered water per day. Herbal teas like licorice, astragalus and reishi mushroom also have antiviral effects.

Limit Caffeine and Alcohol

Both caffeine and alcohol can exacerbate symptoms and promote inflammation in those with EBV. Limit coffee, black tea and alcohol consumption or avoid them altogether.

Following these nutritional strategies along with adequate rest, stress management and exercise can help strengthen your immunity, inhibit EBV and improve health. Be sure to consult your doctor before making any major changes to your diet or supplement regimen.

Supplements That May Help Prevent EBV-Associated Cancers

Supplements may help support immune health. Some options to consider include:

Vitamin C

Vitamin C acts as an antioxidant and helps support immune function - aim for 1,000 mg of vitamin C twice per day.

Vitamin D

Vitamin D helps regulate immune response and may help reduce cancer risk. Most adults need at least 2,000 IU of vitamin D per day. You may need higher doses to reach optimal blood levels of 40-60 ng/mL.

Zinc

Zinc plays an important role in immune health and may have antiviral effects. The typical dosage for EBV is 15-30 mg of zinc picolinate or zinc gluconate once or twice per day. Do not exceed 40 mg per day.

Garlic

Garlic has natural antiviral and immune-boosting properties. Most studies have used aged garlic extract in doses of 600-1,500 mg per day. Garlic supplements may interact with blood thinners, so consult your doctor before using.

Astragalus

The herb astragalus may help boost immune function and has been shown to have antiviral effects against EBV in test tube studies. A typical dosage is 500-1,000 mg of astragalus extract 3-4 times per day. Astragalus can interact with some medications, so check with your doctor first.

In summary, supplements like vitamin C, D and zinc along with L-lysine, garlic and astragalus may help strengthen your immunity and control the reactivation of EBV when used under the guidance of your physician. Lifestyle changes like managing stress, limiting alcohol and quitting smoking can also help keep EBV in remission.

Medications and Other EBV Management Options

If you have been diagnosed with EBV, your doctor may prescribe or recommend certain medications or management options to help control the virus and reduce symptoms. These include:

Antiviral Drugs

Antiviral drugs, such as acyclovir, can be used to treat acute EBV infections and reduce the severity and duration of symptoms. However, antivirals do not eliminate the EBV virus from the body. They are most effective when taken early in the course of infection.

Immunosuppressants

For chronic active EBV infection or EBV-related autoimmune conditions, immunosuppressant drugs may be used to calm an overactive immune system. These include corticosteroids like prednisone, as well as stronger immunosuppressants such as azathioprine. Long-term use of immunosuppressants can have significant side effects, so close monitoring is required.

Symptomatic Relief

In addition to antiviral and immunosuppressant drugs, your doctor may prescribe medication for specific symptoms caused by EBV such as pain relievers for sore throat and joint pain, as well as medication for nausea or other gastrointestinal issues.

Conclusion

In summary, the Epstein-Barr virus is an important health consideration as you age and strive to optimize your wellness. While EBV is extremely common and often asymptomatic, knowing your levels and taking proactive steps to keep the virus in check can have meaningful impacts on your health, longevity, and risk of disease.
