Blood Cancer Awareness Month: Understanding the Enemy

Blood Cancer Awareness Month, observed every September, serves as a powerful reminder of the ongoing fight against various types of blood cancers that silently impact millions worldwide. Despite accounting for approximately 10% of all cancers diagnosed worldwide, blood cancers such as leukaemia, lymphoma, and myeloma remain shrouded in confusion and misconceptions. This month is dedicated to raising awareness, educating the public, and encouraging early detection that can save countless lives. Through collective action and understanding, we can increase awareness and offer hope to those battling these formidable diseases. Let’s break down the barriers of fear and explore the different types of blood cancers along with their symptoms and risk factors. But first, let’s cover the basics. 

What is Blood Cancer?

Blood cancer is a type of cancer that affects the production and function of blood cells. It typically begins in the bone marrow, where blood is produced, and causes abnormal growth of blood cells, particularly white blood cells, which are crucial for the body's immune system. These cancerous cells disrupt the normal functioning of healthy blood cells, leading to symptoms such as fatigue, infections, bruising, and excessive bleeding. The three main types of blood cancers are leukaemia, lymphoma, and myeloma, each affecting different components of the blood and immune system.

How Common is Blood Cancer?

Blood cancer is one of the common forms of cancer worldwide. Each year, it affects millions of people, with an estimated 1.3 million new cases of leukaemia, lymphoma, and myeloma diagnosed globally. In India, it's the fourth most frequently diagnosed cancer, accounting for about 80,000 new cases annually, with leukaemia being the most prevalent, especially in children. Early detection and advances in treatment have improved survival rates, but awareness is still the key to effectively battling this complex disease.

What are the Different Types of Blood Cancer?

Blood cancers are broadly classified into three main types:

1. Leukaemia: Leukaemia originates in the blood and bone marrow, causing an overproduction of abnormal white blood cells that crowd out healthy blood cells. It can be acute or chronic and affects both children and adults.
2. Lymphoma: Lymphoma targets the lymphatic system, which is essential for maintaining the body’s immune defence. There are two primary types—Hodgkin’s lymphoma and non-Hodgkin’s lymphoma—both impacting the lymph nodes, spleen, and other organs.
3. Myeloma: Myeloma affects plasma cells, a type of white blood cell found in the bone marrow. These cancerous cells hinder the production of normal blood cells, leading to bone damage, anaemia, and compromised immunity.

What are the Symptoms and Risk Factors of Blood Cancer?

Blood Cancer Symptoms

Blood cancer symptoms can vary based on the type but often include:

• Unexplained fatigue: If you’re feeling unusually tired or weak despite getting enough rest, it could be a sign of blood cancer. Persistent fatigue that doesn’t improve with sleep is a red flag.
• Frequent infections: Recurrent infections or illnesses that take longer to recover from can indicate a weakened immune system, which might be linked to blood cancers such as leukaemia.
• Unexplained bruising or bleeding: If you’re experiencing frequent bruises, nosebleeds, or bleeding gums without injury, it could signal a blood disorder.
• Swollen lymph nodes: Painless swelling in the neck, armpits, or groyne could suggest lymphoma or other types of blood cancer.
• Bone or joint pain: Persistent pain in bones or joints, especially if it’s unexplained or worsening, may be a symptom of blood cancers like myeloma.
• Night sweats: Sudden and severe night sweats, especially if accompanied by fever or weight loss, may indicate an underlying condition, including blood cancer.
• Unexplained weight loss: If you’re losing weight rapidly without changes in diet or exercise, it could be a sign of a serious health issue, including cancer.
• Shortness of breath or chest pain: Blood cancers can affect the production of healthy blood cells, leading to anaemia or other conditions that cause difficulty breathing or chest pain.

If you’re experiencing one or more of these symptoms, it’s important to consult a healthcare professional for a thorough examination. Early diagnosis can greatly improve the chances of successful treatment and recovery.

Risk Factors

The exact cause of blood cancer is unclear, but several risk factors increase the likelihood of developing it:

• Age: The risk increases with age, especially for lymphoma and myeloma.
• Family history: A family history of blood cancer can raise your risk.
• Exposure to radiation or chemicals: Those exposed to high levels of radiation or chemicals like benzene are at higher risk.
• Weakened immune system: Individuals with compromised immunity, whether due to medical conditions or treatments, face a higher risk.
• Genetic disorders: Conditions like Down syndrome are associated with a higher likelihood of developing blood cancers, especially leukaemia.

Recognising these symptoms and risk factors can lead to earlier detection and better treatment outcomes.

How has Blood Cancer Survival Changed Over Time?

Blood cancer survival rates have significantly improved over time, thanks to advances in medical research, early diagnosis, and more effective treatments. Over the past few decades, the introduction of targeted therapies, immunotherapies, and bone marrow transplants has dramatically enhanced the prognosis for many patients.

For instance, survival rates for certain types of leukaemia, such as chronic myeloid leukaemia (CML), have increased from less than 20% in the 1970s to around 70% today, with some forms even nearing 90% in early-stage diagnoses. Lymphoma and myeloma have also seen substantial improvements in survival, particularly due to breakthroughs in immunotherapy.

In India, while survival rates have improved, we still lag behind the global averages due to delayed diagnosis and limited access to advanced treatments in certain regions. However, awareness, early screening programs, and increasing availability of cutting-edge treatments are helping close this gap, giving patients a better fighting chance.

What is the Significance of Blood Cancer Awareness Month?

The significance of Blood Cancer Awareness Month lies in its ability to bring focus and urgency to a pressing health issue. By concentrating efforts in September, it provides a dedicated platform for raising critical awareness and fostering dialogue about blood cancers. This heightened visibility helps drive research funding, supports advancements in treatment, and promotes early detection, which can significantly improve outcomes. Additionally, it serves as a powerful reminder of the importance of community support and solidarity for patients and families affected by these diseases, encouraging widespread engagement and advocacy.
