Blood Cancer Symptoms That Should Not Be Ignored
Some persistent changes warrant medical assessment because they may reflect abnormal blood-cell production or involvement of the lymphatic system. The table below indicates some blood cancer symptoms and also explains briefly why they should not be ignored:
| Symptom | What It May Indicate? |
| Fever that does not go away or recurrent infections | Abnormally low or abnormal white blood cells leading to weakened immunity |
| Frequent bruising, nosebleeds or bleeding gums | A low platelet count (thrombocytopenia) |
| Lymph node swelling or an enlarged spleen | Accumulation of abnormal blood cells in the lymphatic system, spleen, or liver |
| Persistent bone or back pain | Bone marrow involvement, especially in leukaemia and multiple myeloma |
| Unexplained rapid weight loss coupled with night sweats | Blood cancer progression or increasing activity of the disease |
| Persistent abdominal fullness or swelling | Enlargement of the spleen, liver or abdominal lymph nodes |
| Breathlessness with excessive fatigue | Severe anaemia as a result of reduced red blood cells |
| Small red or purple spots on the skin (petechiae) | Low platelet count needing immediate evaluation |
Why Do Blood Cancer Symptoms Occur?
Blood cancer occurs when abnormal changes in blood-forming or immune cells cause them to grow, survive or multiply uncontrollably instead of developing and functioning normally.
In leukaemia, these abnormal cells build up in the bone marrow and interfere with the production of healthy red blood cells, white blood cells and platelets. This can lead to anaemia, frequent infections, easy bruising and bleeding.
Lymphoma develops when abnormal lymphocytes multiply and collect in lymph nodes or other organs, which may cause swelling, fever, night sweats or unexplained weight loss. Multiple myeloma affects plasma cells in the bone marrow and can lead to anaemia, bone damage, kidney problems and high calcium levels.
Blood Cancer Symptoms That Require Immediate Medical Attention
Emergency medical care is necessary if a person with known or suspected blood cancer develops the following symptoms:
-
Bleeding that does not stop
-
Vomiting blood, coughing up blood or passing black, tar-like stools
-
High fever with severe chills, confusion or marked weakness
-
Severe breathlessness or chest pain
-
Sudden confusion, fainting or loss of consciousness
-
Severe back pain with new leg weakness or numbness
-
Sudden inability to walk or stand
-
Loss of bladder or bowel control
These symptoms can indicate serious infection, major bleeding, severe anaemia, spinal cord compression or another acute complication.
Symptoms of Blood Cancer Based on Type
Blood cancer is not a single disease but a group of cancers that affect different blood cells and tissues. While many symptoms overlap, the pattern and severity of symptoms can vary depending on whether the cancer is leukaemia, lymphoma or multiple myeloma.
Symptoms of these different types of blood cancers are given in the table below:
| Type of Blood Cancer | Symptoms |
| Leukaemia | Fatigue, paleness, frequent infections, fever, easy bruising or bleeding, petechiae, breathlessness and sometimes bone or joint pain |
| Lymphoma | Painless swollen lymph nodes, fever, drenching night sweats, unexplained weight loss, tiredness, itching and sometimes breathlessness or abdominal swelling |
| Multiple Myeloma | Persistent bone pain, particularly in the back, ribs, hips or shoulders; tiredness, breathlessness, weakness, increased thirst, frequent urination and unexplained weight loss |
Symptoms of Blood Cancer in Women
Symptoms of blood cancer may differ in women. The low number of platelets may cause excessive bleeding during periods (menorrhagia), whereas anaemia intensifies symptoms such as fatigue and shortness of breath. If pregnant females have symptoms like continuous fever, unusual bruising, swollen lymph glands, or others, they should get themselves medically examined.
Although these symptoms are not specific to blood cancer and can have many other causes, persistent or unusually heavy menstrual bleeding should be medically assessed, particularly when accompanied by unexplained bruising, paleness or fatigue.
Symptoms of Blood Cancer in Children
Leukaemia is the most common cancer diagnosed in children, although lymphoma and other blood cancers can also occur. Parents may notice the following symptoms in children:
-
Persistent tiredness or unusual weakness
-
Pale skin
-
Repeated fever or infections
-
Easy bruising or unexplained bleeding
-
Frequent nosebleeds
-
Pinpoint red or purple spots on the skin
-
Bone or joint pain
-
Painless swollen lymph nodes
-
Reduced appetite or unexplained weight loss
-
Abdominal swelling or fullness
-
Limping or reluctance to walk because of bone or joint pain
These symptoms are more often caused by conditions other than cancer. Persistent or unexplained combinations of symptoms should nevertheless be assessed by a paediatrician.
Can You Have Blood Cancer Without Symptoms?
Yes. In some cases of blood cancer like chronic lymphocytic leukaemia (CLL) and chronic myeloid leukaemia (CML), symptoms may not be present until later stages of the disease. In some cases, blood abnormalities are noticed in routine blood tests, and the disease is discovered by accident. It is important to conduct further tests in the absence of symptoms to establish the type of cancer.
When Can Blood Cancer Symptoms Become Life-Threatening?
Blood cancers can become life-threatening when they cause severe infection, bleeding, anaemia, neurological complications or major organ dysfunction. Some of these blood cancer symptoms are given in the table below:
| Symptoms | Why It Is Serious |
| High fever with shaking chills, confusion or rapidly worsening weakness | This may indicate a severe infection or sepsis, particularly when normal immune function is impaired. |
| Bleeding that will not stop, vomiting blood or passing black stools | A very low platelet count or clotting abnormality may cause serious internal or external bleeding. |
| Severe breathlessness, chest pain, dizziness or fainting | Severe anaemia or another cardiovascular or respiratory complication may reduce oxygen delivery to vital organs. |
| Severe headache, vomiting and sudden confusion | In some acute leukaemias, these symptoms may indicate serious bleeding or neurological complications. |
| Severe back pain with leg weakness, numbness or loss of bladder or bowel control | In multiple myeloma, these symptoms may indicate spinal cord compression and risk permanent neurological damage. |
| Extreme thirst with vomiting, confusion and marked weakness | In multiple myeloma, this pattern may indicate severe hypercalcaemia. |
| Sudden breathlessness, confusion, weakness or visual changes with an extremely high white-cell count | Rarely, acute leukaemia can cause leukostasis, which interferes with blood flow to the lungs or brain. |
How are Blood Cancer Symptoms Diagnosed?
Doctors employ the following diagnostic procedures in determining whether symptoms are related to blood cancer:
| Diagnostic Test or Assessment | Purpose |
| Medical history and physical examination | Reviews symptoms and checks for paleness, bruising, enlarged lymph nodes, spleen or liver |
| Complete blood count (CBC) with differential | Measures red cells, different white-cell types and platelets; particularly important when leukaemia is suspected |
| Peripheral blood smear | Examines the appearance and maturity of blood cells |
| Bone marrow aspiration and biopsy | Examines bone marrow cells and is important for diagnosing and classifying many leukaemias and multiple myeloma |
| Flow cytometry | Identifies abnormal cell populations and helps classify many leukaemias and some lymphoid cancers |
| Cytogenetic and molecular tests | Look for chromosome or gene changes that help define the exact blood cancer |
| Lymph node biopsy | Removes lymph node tissue for examination and is a key test when lymphoma is suspected |
| Serum protein and free light-chain tests | Looks for abnormal monoclonal proteins when multiple myeloma is suspected |
| CT, PET-CT, MRI or whole-body imaging | Assesses lymph nodes, organs, bone marrow or bone involvement according to the suspected cancer |
FAQs
-
Q1. What is the first symptom of blood cancer?
Ans: Fatigue, infection, or swollen lymph nodes without pain could be one of the first symptoms of blood cancer. -
Q2. Can blood cancer develop without symptoms?
Ans: Certainly. Chronic blood cancers may have no symptoms at all and may be discovered through blood test results. -
Q3. What are the last-stage blood cancer symptoms?
Ans: Blood cancer symptoms at the later stages may include excessive tiredness, infections, uncontrolled bleeding, bone pains, weight loss, difficulty in breathing, or confusion. These symptoms need immediate medical attention.
