Blood cancer symptoms and signs

Blood cancer is an umbrella term for malignancies that affect the production and function of your blood cells. Unlike solid tumours that you can feel or see on a scan, blood cancer is often invisible in its early stages, hiding within the bone marrow and lymphatic system. Recognising the warning signs early is the most critical step toward successful management and survival.

This blog cuts through the medical jargon to provide a clear analysis of blood cancer symptoms. Whether you are concerned about recent health changes or simply educating yourself, understanding these signals is vital.

What Is Blood Cancer?

Before diving into the symptoms, it is essential to understand the source. Blood cancer occurs when the DNA within blood cells mutates. This causes the bone marrow to produce abnormal cells that grow uncontrollably, crowding out the healthy red blood cells, white blood cells, and platelets your body needs to survive.

The three main types of blood cancer are:

• Leukaemia: Cancer of the white blood cells.
• Lymphoma: Cancer of the lymphatic system.
• Myeloma: Cancer of the plasma cells.

Common Symptoms of Blood Cancer

While symptoms vary depending on the specific type of cancer, there is a cluster of general warning signs that appear across Leukaemia, Lymphoma, and Myeloma. These are often vague and easily mistaken for the flu or general stress. However, the key differentiator is persistence.

The most common early blood cancer symptoms include unexplained fatigue that doesn’t go away with sleep, drenching night sweats, and swollen lymph nodes in the neck or armpit.

If you experience the following signs of blood cancer for more than two weeks, medical investigation is necessary. Read on to know the following are the key signs and symptoms of blood cancer in detail:

1. Persistent Fatigue and Weakness

This is not the tiredness you feel after a long day at work. This is extreme fatigue that does not improve with rest or sleep. It is often caused by anaemia (a lack of red blood cells), leaving you feeling physically drained, breathless, and unable to perform daily tasks.

2. Unexplained Weight Loss

Losing weight without changing your diet or exercise routine is a major warning sign. Cancer cells consume massive amounts of energy, and the body alters its metabolism in response. If you have lost significant weight unintentionally, consult a haematologist immediately.

3. Frequent or Severe Infections

White blood cells are your body’s defence army. In blood cancer, these cells are abnormal and cannot fight bacteria or viruses effectively. If you are suffering from recurrent infections, lingering coughs, or mouth ulcers that refuse to heal, it indicates your immune system is compromised.

4. Unexplained Bruising and Bleeding

When blood cancer crowds out healthy platelets (which help blood clot), you may notice:

• Easy bruising with no memory of injury.
• Prolonged bleeding from minor cuts.
• Frequent nosebleeds.
• Heavy periods in women.
• Petechiae: Tiny, pin-prick red or purple spots under the skin that do not fade when pressed.

5. Drenching Night Sweats

Many patients report waking up soaking wet, requiring a change of bedsheets. While night sweats can be hormonal, they are also a classic systemic symptom of Lymphoma and Leukaemia.

6. Swollen Lymph Nodes

Painless lumps in the neck, armpit, or groin are caused by a build-up of abnormal white blood cells in the lymph glands. Unlike infection-based swelling, these lumps are often painless and rubbery to the touch.

7. Bone and Joint Pain

This is particularly common in Multiple Myeloma and Acute Lymphoblastic Leukaemia (ALL). As the bone marrow becomes overcrowded with cancer cells, it can cause deep, aching bone pain in the back, ribs, and hips.

Specific Symptoms by Cancer Type

While the above symptoms are general, certain signs point toward specific blood conditions.

Leukaemia Symptoms

Leukaemia symptoms develop based on whether the cancer is acute (fast-growing) or chronic (slow-growing).

• Acute Myeloid Leukaemia (AML) often presents with sudden, severe illness, high fever, and shortness of breath.
• Chronic Leukaemia may be asymptomatic for years, often discovered accidentally during a routine blood test.
• Pale skin (Pallor) occurs due to fewer red blood cells.

Lymphoma Symptoms

Lymphoma specifically targets the lymphatic system, the body’s disease-fighting network. The following are the distinct signs and symptoms for lymphoma:

• Painless Swelling: The most frequent symptom for non-hodgkin & hodgkin lymphoma is a lump in the neck, armpit, or groin. Unlike an infection, these swollen lymph nodes are usually painless and feel rubbery or firm.
• Abdominal Pain: If the spleen becomes enlarged, it presses on the stomach, causing a feeling of fullness after eating only a small amount, or general bloating.
• Itchy Skin: Unexplained, severe itching (pruritus) without a visible rash is a unique symptom of Hodgkin Lymphoma. It can be localized or affect the whole body.
• Alcohol Sensitivity: Rarely, some people with lymph nodes affected by Hodgkin Lymphoma feel immediate pain in those nodes after drinking alcohol.
• Chest Pain and Cough: If Non-Hodgkin Lymphoma affects the thymus or lymph nodes in the chest, it can press on the windpipe. This leads to a persistent dry cough, chest pain, or difficulty breathing, even whilst resting.
• Unexplained Fatigue: Patients with Non-Hodgkin Lymphoma often report a deep, debilitating tiredness (fatigue) that does not improve with sleep, signalling that the body is fighting the cancer cells.

Myeloma Symptoms

Myeloma symptoms arise because the cancer affects plasma cells, causing them to multiply uncontrollably in the bone marrow and produce abnormal proteins.

• Bone Pain and Fractures: This is the most common warning sign of Multiple Myeloma. The cancer weakens the bones, leading to deep, persistent pain (often in the back, ribs, or hips) and causing bones to fracture easily from minor stress or injury.
• Kidney Problems: The production of abnormal proteins (M proteins) can damage the kidneys. This often leads to kidney failure, indicated by a decrease in urination, swelling in the legs, and extreme thirst.
• High Calcium Levels (Hypercalcaemia): As bones break down, calcium is released into the bloodstream. This condition, known as hypercalcaemia, causes symptoms like confusion, severe thirst, stomach pain, and constipation.
• Recurrent Infections: Because the cancerous plasma cells crowd out healthy antibody-producing cells, the immune system is weakened. Patients often suffer from frequent bacterial infections, particularly pneumonia.
• Nerve Damage (Spinal Cord Compression): If weakened bones in the spine collapse, they can press on the spinal cord or nerves, causing numbness, tingling, or weakness in the legs.

Symptoms on Different Skin Tones

Healthcare guidance often focuses on lighter skin, but blood cancer symptoms may appear differently on Black, Asian, and Brown skin tones. It is crucial to know what to look for:

• Bruising: On darker skin, bruises may not look blue or purple. They may appear dark brown or black and feel tender/warm to the touch.
• Rashes/Petechiae: On brown skin, these tiny spots may look purple or darker than the surrounding skin.
• Pallor: You may not look “pale” in the face. Instead, check the palms of the hands, nail beds, and the inside of the lower eyelid. If the inner eyelid is pale pink or white rather than dark pink/red, it indicates anaemia.

Stages of blood cancer

Staging is a method to characterise the degree how much the cancer has grown and spread to other organs. The doctor uses these stages to plan a precise treatment plan for the patient according to their condition. The stages of blood cancer are:

• Stage 1 – Cancer has not spread that much but there are enlarged lymph nodes.
• Stage 2 – The organs near major lymph nodes are affected such as the liver, spleen, and other lymph nodes.
• Stage 3 – Problems like anaemia have started to appear in stage 3 along with the issues mentioned above.
• Stage 4 – In the 4th stage, other vital organs have started to get affected and the rate of blood platelets falls down sharply.

When to See a Doctor: Navigating Care in India

While blood cancer is becoming increasingly prevalent in India, the curability rates are very high when the disease is caught early. It is easy to blame a persistent cough on pollution or tiredness on the heat, but assuming these symptoms are harmless can be dangerous. “Time is tissue”—meaning the faster you act, the better your chances.

Here is a practical guide on when and where to seek help in India.

The 2-Week Rule

Do not wait for symptoms to disappear on their own. If you experience persistent symptoms—especially unexplained fatigue, lumps, or night sweats—for more than two weeks without a clear cause (like a known infection), you must take action. While a General Practitioner (GP) is a good starting point, if symptoms persist, you must move beyond basic care and consult a leading hemato-oncologist in India or the oncologist.

When is it an Emergency?
Some types of cancer, such as Acute Leukaemia, can progress rapidly. You should seek immediate emergency care if you or a loved one experience:

• Sudden confusion or vision changes.
• Uncontrollable bleeding from the nose or gums.
• Severe breathlessness even while resting.
• Seizures or loss of consciousness.

Diagnosis and The Path Forward

A blood cancer diagnosis involves a structured detective process that typically begins with a Complete Blood Count (CBC) to detect abnormal levels of red cells, white cells, or platelets. If red flags appear, a Peripheral Blood Smear allows a haematologist to visually examine the shape of the cells under a microscope. To confirm the specific type of cancer, the gold standard is a Bone Marrow Biopsy, where a sample is extracted from the hip bone to analyse genetic mutations. This is often supported by Imaging Scans (like PET/CT or MRI) to map the cancer’s spread, and advanced Flow Cytometry to identify the exact cellular subtype, ensuring the chosen blood cancer treatment is perfectly targeted.
