Risk Factors of Blood Cancer

Certain factors can increase one’s risk of developing blood cancer. Having these risk factors does not guarantee blood cancer development; however, it does indicate a higher probability of developing it.

That said, being aware of different risk factors associated with blood cancer may aid in informed decision-making with respect to blood cancer treatment.

The following are the different blood cancer risk factors:

1. Radiation Exposure

Radiation exposure is a common blood cancer risk factor. The higher the doses, the greater the risk of developing blood cancers, such as leukemia. This is due to DNA damage from previous cancer treatments or exposure during occupations. Such damage can lead to mutations, resulting in the growth of abnormal cells. People who are exposed to radiation have a higher chance of developing blood cancers many years after exposure.

Age Related

Age plays a major role when determining the high-risk factors for ALL leukemia. Acute lymphoblastic leukemia is commonly found in kids, though it is seen among adults as well. Kids who are between the ages of 2 and 5 are at the highest risk of getting this type of cancer.

2. Certain Chemicals

Exposure to certain hazardous chemicals is another blood cancer risk factor, especially leukemia and lymphoma. Prolonged exposure to some substances, such as benzene in the manufacturing industry, formaldehyde in certain occupations, and certain pesticides in agriculture, can damage the bone marrow and interfere with the normal production of blood cells. These chemicals lead to genetic mutations that lead to uncontrollable growth of abnormal (cancerous) cells. Individuals working with these chemicals should pay extra attention to protecting themselves against prolonged exposure. Also, periodic health monitoring should be conducted to detect any disorders.

3. Lowered Immunity

Reduced immunity is an important blood cancer risk factor. A weakened system loses immune power and fails to detect or destroy malignant cells. Conditions that cause compromised immunity include HIV/AIDS, autoimmune diseases, and prolonged use of immunosuppressive medication after organ transplantation. Some patients with immunodeficiency are prone to chronic inflammation, which may also lead to cancer development. Therefore, healthy living, timely vaccinations, and regular health check-ups may help reduce blood cancer risk.

4. Family History

Family history is also a significant blood cancer risk factor since some of the genetic predispositions would be linked to an increased risk of conditions like leukemia or lymphoma. People with first-degree relatives diagnosed with blood cancer are considered to have a higher risk due to inherited mutations or exposure to similar risk factors in the environment. Some syndromes, for instance, Li-Fraumeni or Down syndrome, will also raise this risk. Knowing family history will identify many individuals at early stages and result in proactive surveillance.

5. Inherited Conditions

The risk of blood cancer is also found to be associated with certain inherited genetic disorders. Genetic conditions like Fanconi anemia, Bloom syndrome, and Li-Fraumeni syndrome cause increased susceptibility to leukemia or lymphoma. These conditions are related to defective DNA repair mechanisms or chromosome instability. Many such disorders induce abnormal cell growth and predispose the healthy cells towards malignancy. For inherited syndromes, consultation should include genetic counseling and routine health check-ups to ensure early detection and timely intervention.

6. Age

The risk of blood cancer is usually higher in elderly patients, and incidence increases with age. Most blood cancers, including leukemia and lymphoma, have been reported in adults as well as the elderly of the age group higher than 60 years. The possible reason for age being a risk factor for blood cancer may be the accumulation of genetic mutations and immune system degradation that occur with aging.

7. Ethnicity

Ethnicity has long been recognized as a significant blood cancer risk factor, as certain ethnic groups are prone to developing certain types of blood cancer. Studies reported a higher risk of acute lymphoblastic leukemia in White and Hispanic children, while Asian children have a higher risk of developing acute myeloid leukemia. These differences relate to genetic predispositions, environmental exposures, and lifestyle factors.

How To Avoid/Prevent Blood Cancer?

In this section, let us discuss the solution to a burning question - “How to prevent blood cancer?”

While it is not possible to prevent blood cancer or achieve 100% lymphoma or leukemia prevention, it may be possible to reduce its risk with appropriate preventative measures.

The following are a few measures that may reduce the risk of blood cancer:

1. Eat Healthy Food

Healthy eating can be one of the effective preventative measures against blood cancer. A balanced diet provides all the essential nutrients necessary for immune and cellular functions. Foods rich in fiber and proteins can help maintain the ideal weight, reduce inflammation, and potentially prevent blood cancer. In addition, increased consumption of healthy fats from fish and nuts would likely improve overall well-being and help the immune system identify and attack cancer cells effectively.

2. Take Rest

Good sleep strengthens the body's immune system and helps it fight abnormal cell development and potentially prevent blood cancer. Inappropriate sleep is linked to increased inflammation and stress, interfering with tissue healing.

3. Protect Yourself From Infection

Protection from infections is important to prevent blood cancer, especially in immunocompromised patients. Good hygiene, including frequent handwashing and avoiding contact with seriously infected people, reduces exposure to pathogens. Immunization also increases the level of immunity. Healthy eating habits and exercise maintain a healthy lifestyle that reduces infection risk and blood cancer risks.

4. Exercise

Regular exercise is a good habit that helps prevent blood cancer. Being fit and maintaining a healthy weight is essential, as being overweight or obese is a significant risk factor for blood cancers. Exercise also improves the immune system, increases circulation, and reduces inflammation. Moderate exercises include walking, swimming, or cycling.

5. Maintain an Emotional Health

Chronic stress and negative emotions weaken the immune system and make the body susceptible to various diseases, including cancer. Maintaining emotional health, on the other hand, can improve overall well-being and thereby potentially prevent blood cancer. Improving emotional strength involves practicing mindfulness and meditation, engaging in hobbies, building robust social connections, and seeking help from friends or professionals. These activities are crucial in improving emotional health and enhancing the quality of life, which can help lower the risk of developing blood cancer.

6. Talk to Therapist

Studies have found that persistent stress and anxiety conditions can weaken a person's immunity. Therefore, maintaining optimum mental health also plays a critical role in reducing blood cancer risk. Those with mental health disruptions may reach out to a therapist to manage them effectively through counseling. Counseling provides an environment for psychological evaluation, developing coping plans, and managing stress effectively. Strength builds up and brings positive thinking about life. Subsequently, a person's health improves, which might lower the risk of developing all cancers, including blood cancer. If you are looking for more information on appropriate measures to reduce blood cancer, you may reach out to the preventive oncology team at your nearby HCG Cancer Centre.

Who is at High Risk of Blood Cancer?

People with a higher risk of developing blood cancer include those who have a family history, inherited genetic disorders, past anticancer therapies, exposure to chemicals or radiation, and a compromised immune system. Additionally, increasing age and ethnicity may also contribute to the increased risk of blood cancer.

Conclusion

The exact cause of developing blood cancers is not known. However, certain factors increase the risk of blood cancer. These factors include radiation exposure, exposure to certain chemicals, lowered immunity, family history, inherited conditions, age, and ethnicity. While it is not possible to prevent blood cancer completely, it is possible to reduce its risk. These include eating healthy food, resting adequately, protecting from infection, performing routine exercise, maintaining emotional health, and talking to a therapist.

Frequently Asked Questions

How does age affect the risk of blood cancer?

Blood cancer can affect individuals from any age group. Certain blood cancer types are relatively more common among children and young adults, while others are more common among older adults.

In the geriatric age group, individuals are at higher risk of developing lymphoma, myeloma, and leukemia. The rate at which the body is exposed to various mutations and the decline in the body’s immunity with age contribute to increased susceptibility to blood cancers among older adults.

Blood cancer could go undetected for months or years as the symptoms are very vague in the early stages.

The only way a person can be diagnosed with blood cancer early is through regular check-ups and paying attention to different blood cancer symptoms.

One may reduce their blood cancer risk by avoiding processed foods containing high sugar levels, saturated fats, artificial sweeteners, and additives. Avoiding the consumption of refined carbohydrates along with red and processed meats and refraining from excessive alcohol consumption may help reduce the risk of various cancers, including blood cancer. Emphasis should be on a well-balanced diet high in fruits, vegetables, and whole grains.

Although donations do not directly reduce the risk of blood cancer, they may help detect the disease during check-ups and screenings required during blood donation.
