How Is Blood Cancer Diagnosed?

Picture this: you’ve got your normal, well-behaved blood cells just doing their thing, and then in walks these troublemakers—abnormal blood cells—ready to stir the pot. It’s like they missed the memo on personal space and boundaries. The unwelcome guest we’re highlighting is blood cancer, a term that covers a range of malignancies affecting our blood, bone marrow, and lymphatic systems.

Approximately 10% of cancer diagnoses in the US are blood cancers, meaning that roughly 185,000 people will be diagnosed with it in 2023. But fear not, because we’re here to provide you with the know-how on all forms of blood cancer. Whether you’re confronting these rogue cells firsthand or standing alongside a loved one who is dealing with them, brace yourself to navigate the realm of blood cancers with unwavering determination.

Navigating the Many Faces of Blood Cancer

The breadth of blood cancer types is vast and varied, each type with its own nuances and symptoms. Here’s how to determine what type of blood cancer you may be coming face to face with.

Acute Lymphoblastic Leukemia (ALL) 

Meet Acute Lymphoblastic Leukemia, commonly referred to as ALL. This major agitator sets up shop in the bone marrow, the body’s hub for blood cells. It progresses quickly, producing an abundance of immature blood cells rather than the mature ones our bodies need. ALL primarily attacks lymphocytes, our vital white blood cells. As for the symptoms of Acute Lymphoblastic Leukemia? We’re talking fatigue, weakness, recurring fever and infections, easy bleeding and bruising, bone and joint pains, swollen lymph nodes, and a surprise cameo of unexpected weight loss. 

Chronic Lymphocytic Leukemia (CLL) bears a strong resemblance to ALL. The primary difference lies in their progression speed. CLL develops more gradually, earning its “chronic” designation. For a significant period, many individuals might remain symptom-free. However, when symptoms do emerge, they mirror those associated with ALL.

Acute and Chronic Myeloid Leukemia

Acute Myeloid Leukemia targets the chameleons of our cell world: our myeloid cells, known for their shape-shifting abilities into red blood cells, specialized white blood cells, or platelets. If you’re faced with AML, brace yourself for an assortment of symptoms such as persistent tiredness, breathlessness, unintended weight loss, repeated infections, fever, night sweats, unusual and frequent bleeding, and a noticeable paleness to the skin.

Chronic Myeloid Leukemia (CML), like AML, affects the myeloid cells. Its progression mirrors that of CLL, particularly in the chronic phase. This slow development is somewhat of a silver lining—it’s like having a reliable GPS that helps detect and address this blood cancer in a timely manner.


In the world of Lymphoma, navigating its complexities is akin to understanding a family tree. At its roots, you find two main branches: Non-Hodgkin and Hodgkin Lymphoma. Venture into the Non-Hodgkin branch, and you’ll encounter siblings, B-Cell and T-Cell. B-cell Lymphoma, often seen as the more prevalent sibling, originates from the diligent B lymphocytes that produce antibodies. In contrast, T-cell Lymphoma comes from the T lymphocytes, cells that are always on guard to combat those unwelcome infected cells and bolster our immune defenses. For both, the cancerous lymphocytes grow uncontrollably, disrupting the immune system’s functionality and potentially metastasizing throughout the body.

Those navigating the lymphoma journey frequently grapple with telling symptoms like swollen lymph nodes, persistent fatigue, and nocturnal sweats. Yet, what sets Hodgkin Lymphoma apart is its signature characteristic: the distinctive Reed-Sternberg cells, unusually large cells found within the lymph nodes.


Myeloma, occasionally termed the “subtle disruptor” and more widely recognized as multiple myeloma, is a notable entity in the cancer domain. It originates in plasma cells, the diligent white blood cell specialists that produce our body’s defensive antibodies. These cells begin an unexpected overgrowth, expanding aggressively within the confines of the bone marrow. This unchecked multiplication leads to an influx of irregular antibodies. The implications? These antibodies can compromise our kidney function and exert undue stress on our bones, presenting a series of hurdles for the body to navigate.

What are the Risk Factors for Blood Cancer?

Blood cancer may seem like a formidable opponent. But it becomes much more manageable when we shine a light on its potential triggers. So, let’s take a plunge into the factors that might increase a person’s chances of developing blood cancer.

The Role of Genetics and Age

If blood cancer has left its mark on a close family member—a parent, a sibling, or a child—you might want to lean in a bit closer. Specific syndromes and disorders may elevate your risk: 

  • Down Syndrome
  • Li-Fraumeni Syndrome
  • Fanconi Anemia
  • Ataxia-Telangiectasia
  • Hereditary hematologic disorders
  • Inherited immune system abnormalities
  • Mutations in the BRCA1 and BRCA2 genes

Age also plays a major role in the development of blood cancers. While many of these malignancies prefer the seasoned chapters of one’s life, acute lymphoblastic leukemia often casts its shadow in the early stages of childhood.

Where Daily Habits Meet Hidden Hazards

Every day, we might encounter invisible hazards such as high doses of radiation or pesticides. Prolonged exposure to these can increase our risk of developing blood cancer. Lurking chemicals like benzene, which can be found in gas, cigarette smoke, or in some glues, paints, furniture wax, and detergents, can also up your risk.

The daily choices we make and the habits we adopt can serve as either our shield or our undoing. The weight of our decisions, quite literally, matters, as being obese or overweight can elevate our risks. Thus, making healthy decisions—like maintaining an optimal weight, forgoing that extra drink, opting for a balanced diet, and soaking up some sunshine—can steer us toward a brighter, cancer-resistant path.

Past Treatments, Present Implications

Past medical conditions can provide valuable insights into our health patterns that might be relevant in the realm of blood cancers. Those with an autoimmune disease or a compromised immune system, whether due to conditions like HIV/AIDS or protective medications, tread a distinct path. In the same vein, certain viral markers, such as Epstein-Barr virus (EBV), Human T-lymphotropic virus (HTLV-1), and Hepatitis C virus (HCV), leave imprints tied to specific blood cancers. Previous treatments like chemotherapy or radiation therapy, as well as conditions like rheumatoid arthritis, can also compound your risk.

What Can You Do? Tests and Treatments for Blood Cancer

Decoding the enigma of blood cancer is like piecing together a complex puzzle, with each test revealing a bit more of the bigger picture. The process often starts with blood tests, which measure the counts of red blood cells, white blood cells, and platelets in one’s system. But that’s just the tip of the iceberg. Here are other advanced tests that can help you delve deeper into the elusive signs of blood cancer:

  • Bone Marrow Tests
  • Imaging Studies
  • Lumbar Puncture
  • Genetic and Molecular Testing

These diagnostic tools and tests can provide a comprehensive picture of your health status, ensuring that patients receive the most appropriate and effective care tailored to their specific condition. And thankfully, there are a variety of treatment options tailored to individual patients’ needs. Some of the primary treatments for blood cancer are chemotherapy, radiation therapy, targeted therapy, immunotherapy, and stem cell transplantation.

Blood Battles: Empowering Yourself as a Blood Cancer Advocate

Getting into the complexities of blood cancers has highlighted the progress of medical science and the enduring strength of individuals. For every type of abnormal cell, there’s a dedicated specialist. Every diagnostic test brings clarity, and each treatment offers a pathway to recovery. Whether you’re the patient or a supportive ally, you now possess a greater understanding to confront blood cancer effectively—and let’s face it, you’re practically a blood cell detective now!
