Affinity Health, a leading provider of high-quality health cover, offers essential information on recognising the signs of blood cancer.
Blood cancer may not always show up with apparent symptoms, but early detection can be life-saving.
World Blood Cancer Day is on 28 May, so it’s crucial to raise awareness about the early warning signs.
According to Worldwide Cancer Research, blood cancers are the fifth most common type of cancer globally, with approximately 1.3 million new cases diagnosed worldwide in 2020.
“The good news is that ongoing research continues to improve how we detect and treat cancer, giving patients a better chance at recovery and quality of life,” says Murray Hewlett, CEO of Affinity Health.
“Blood cancer is often misunderstood and can go undiagnosed for a long time, especially when the symptoms are mild or easy to overlook.”
What Is Blood Cancer?
Blood cancer is a type of cancer that affects how blood cells are made and how they work. It usually starts in the bone marrow or lymphatic system and can spread quickly if not treated. Blood cancer can affect anyone—children, adults, or seniors, and often develops quietly, without clear warning signs. There are three main types:
- Leukaemia affects the blood and bone marrow and can develop rapidly (acute) or slowly (chronic).
- Lymphoma begins in the lymphatic system and includes Hodgkin and non-Hodgkin lymphoma.
- Myeloma is a cancer of plasma cells that weakens the immune system and bones.
Early Symptoms and Warning Signs
Blood cancer symptoms are easy to overlook, especially early on. That’s why it’s important to know what to watch for. Common early symptoms include:
- Weakness or persistent fatigue.
- Frequent infections.
- Unexplained weight loss.
- Swollen lymph nodes (especially neck, armpits, or groin).
- Easy bruising or bleeding.
- Night sweats.
- Bone or joint pain.
- Ongoing fever without a clear cause.
While these symptoms could be linked to other illnesses, they should never be ignored—especially if they persist.
Why Early Diagnosis Matters
Early diagnosis improves the chances of successful treatment and better outcomes. However, because the symptoms often mimic other less serious illnesses, people may delay seeing a doctor or dismiss their symptoms entirely.
How Blood Cancers Are Diagnosed
Doctors usually start checking for blood cancer with a blood test, which can show if something’s not right with your blood cells. If more tests are needed, they might suggest:
- Taking a small sample of bone marrow.
- Doing scans such as a CT, PET, or MRI.
- Testing a swollen lymph node.
What Treatment Looks Like
Treatment varies based on the type and stage of the cancer and the patient’s overall health. Common treatments include:
- Chemotherapy.
- Radiation therapy.
- Targeted therapy or immunotherapy.
- Stem cell or bone marrow transplants.
With ongoing advances in medicine, many people with blood cancer go on to lead whole lives, especially when treatment starts early.
