Leukemia is a type of cancer that affects the blood-forming tissues, including the bone marrow and lymphatic system. It leads to the overproduction of abnormal white blood cells, which impairs the body's ability to fight infections and hinders the production of red blood cells and platelets.​

Common clinical features

The clinical features of leukemia can be subtle and nonspecific, especially in its early stages. Recognizing these signs is crucial for prompt diagnosis and treatment.​

General symptoms:

  • Fatigue and weakness: Due to anemia caused by a shortage of red blood cells.​
  • Frequent infections: Resulting from a lack of healthy white blood cells.​
  • Fever or chills: Often without an apparent cause.​
  • Unexplained weight loss: A common symptom in many cancers, including leukemia.​
  • Swollen lymph nodes: Especially in the neck, armpits, or groin.
  • Easy bruising or bleeding: Such as frequent nosebleeds or bleeding gums.​
  • Petechiae: Small red spots under the skin caused by bleeding.​
  • Bone or joint pain: Due to the spread of leukemia cells to the bone surface or joint.​
  • Enlarged liver or spleen: Leading to abdominal discomfort.​

These symptoms can vary depending on the type of leukemia and its progression.

Diagnostic approaches

Early detection of leukemia significantly improves treatment outcomes. The diagnostic process typically involves:​

  • Physical examination: Checking for signs like pale skin, swelling of lymph nodes, or enlargement of the liver and spleen.​
  • Blood tests: A complete blood count (CBC) can reveal abnormal levels of white blood cells, red blood cells, and platelets.​
  • Bone marrow biopsy: Extracting a sample of bone marrow to look for leukemia cells.​
  • Imaging tests: Such as X-rays, CT scans, or MRIs to detect the spread of leukemia.​
  • Genetic tests: Identifying specific genetic mutations can help determine the type of leukemia and guide treatment.​

Considering future options: cryopreservation

Facing a diagnosis of leukemia can be overwhelming, especially when treatment options are limited. In such cases, exploring future-oriented possibilities becomes essential.​

At Tomorrow.bio, we offer human cryopreservation—a process of preserving individuals at low temperatures after legal death, with the hope that future medical advancements may allow for revival and treatment. While not a cure, it represents an opportunity to bridge today's limitations and tomorrow's possibilities.​

We understand the emotional weight of a terminal diagnosis. Our team is here to provide information and support, helping you make informed decisions about your future.​

The latest insights on cryonics, delivered each monday morning.

About Tomorrow.bio

At Tomorrow.bio, we are dedicated to advancing the science of cryopreservation with the goal of giving people a second chance at life. As Europe’s leading human cryopreservation provider, we focus on rapid, high-quality standby, stabilization, and storage of terminal patients—preserving them until future medical technologies may allow revival and treatment.​

Our mission is to make human cryopreservation a reliable and accessible option for everyone. We believe that no life should end because current medical capabilities fall short.​

Our vision is a future where death is optional—where people have the freedom to choose long-term preservation in the face of terminal illness or fatal injury, and to awaken when medicine has caught up.​
