Blood cancer cases are rising globally, with doctors warning that many people continue ignoring early symptoms until the disease reaches advanced stages. On World Blood Cancer Day, health experts are urging people to become more aware of subtle warning signs linked to leukemia, lymphoma, and multiple myeloma — the three main types of blood cancer.
Unlike many solid tumours, blood cancers often develop silently, making them difficult to detect in the early stages. Symptoms are frequently mistaken for stress, viral infections, weakness, or fatigue, leading to delayed diagnosis.
According to Dr. Rahul Bhargava, Director and Head of Hematology at Fortis Memorial Research Institute, Gurugram, early detection can significantly improve treatment success and survival rates.
“One of the biggest challenges with blood cancer is that its symptoms often appear vague initially. Persistent fatigue, unexplained fever, frequent infections, or unusual bruising should never be ignored if they continue for weeks,” he says.
Blood cancers affect the production and function of blood cells inside the bone marrow and lymphatic system. As abnormal blood cells multiply, they interfere with the body’s ability to fight infections, carry oxygen, and clot blood properly.
Among the most common symptoms doctors urge people to watch for are:
- Constant tiredness or weakness
- Recurrent infections
- Unexplained fever
- Sudden weight loss
- Swollen lymph nodes
- Night sweats
- Bone pain
- Easy bruising or bleeding
- Pale skin
- Shortness of breath
Experts say leukemia commonly affects white blood cells, while lymphoma targets the lymphatic system. Multiple myeloma affects plasma cells, which are responsible for producing antibodies.
Doctors note that although blood cancers are more common in older adults, younger adults and even children are increasingly being diagnosed with leukemia and lymphoma.
“People often assume cancer always causes severe pain in the beginning, but blood cancer can progress silently. Sometimes patients discover it only after a routine blood test,” explains Dr. Bhargava.
Several factors may increase blood cancer risk, including family history, smoking, radiation exposure, weakened immunity, obesity, and prolonged exposure to harmful chemicals such as benzene.
Fortunately, advancements in medical science have improved survival rates significantly over the years. Treatment options now include chemotherapy, immunotherapy, targeted therapy, radiation therapy, stem-cell transplantation, and personalised cancer treatments.
Doctors stress that awareness plays a major role in early diagnosis. Ignoring symptoms for months may allow the disease to progress rapidly, making treatment more complicated.
Health experts also encourage people to avoid self-diagnosing online. Symptoms such as fatigue or fever may occur due to several harmless conditions, but persistent unexplained changes in the body should always be evaluated by a doctor.
Regular health check-ups and routine blood tests can help identify abnormalities before severe complications develop. Experts say listening to your body and seeking timely medical attention remains one of the most important steps in fighting blood cancer.
On World Blood Cancer Day, doctors remind people that early awareness can save lives. Recognising warning signs and seeking prompt medical advice may make a critical difference in diagnosis, treatment, and long-term recovery.
