Anemia is a prevalent blood disorder that affects millions of people worldwide. Reduced hemoglobin levels or a decrease in the number of red blood cells (RBCs) are its defining features. The protein in RBCs called hemoglobin is in charge of transporting oxygen from the lungs to the rest of the body. A decrease in RBCs or hemoglobin can lead to various health complications. While there are numerous causes of anemia, such as iron deficiency, vitamin deficiencies, and genetic disorders, a frequently asked question is, “can anemia be caused by cancer?”
The goal of this article is to give readers a thorough grasp of the connection between anemia and cancer. We will explore the connection between cancer and anemia. The article will also explore the signs and symptoms that may suggest a link between the two conditions. Additionally, we will delve into the connection between low hemoglobin levels and cancer. Furthermore, shedding light on the potential mechanisms cancer can contribute to anemia. Additionally, we will discuss the available treatment options for anemia caused by cancer. It will provide valuable information for patients and healthcare providers seeking to manage this complex and often the challenging medical issue.
Understanding Anemia and Cancer
Anemia Sign of Cancer
Anemia can be a sign of cancer, particularly if it is persistent or unresponsive to traditional iron or vitamin deficiency treatments. Certain types of cancer, such as leukemia or lymphoma, directly affect the production of red blood cells in the bone marrow. It can lead to anemia as a result of cancer. Other cancers, such as those of the gastrointestinal tract, may cause blood loss, leading to anemia.

Low Hemoglobin and Cancer
Low hemoglobin levels are often an indicator of anemia. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen throughout the body. It can happen in several ways:
Reduced red blood cell production:
Cancers that affect the bone marrow, such as leukemia, can interfere with the production of red blood cells.
Blood loss:
Tumors in the gastrointestinal tract can cause bleeding. It leads to a reduction in the number of red blood cells and low hemoglobin levels.
Hemolysis:
Some cancers release substances that can prematurely break down red blood cells. It causes low hemoglobin levels.
Anemia Caused by Cancer: Symptoms and Diagnosis
Anemia Cancer Symptoms
The symptoms of anemia caused by cancer are similar to those of other forms of anemia. These symptoms may include:
- Fatigue
- Weakness
- Shortness of breath
- Dizziness
- Pale skin
- Chest pain
- Cold hands and feet
- Rapid or irregular heartbeat
It is essential to consult a healthcare professional if you are experiencing these symptoms, as they may indicate underlying cancer or another medical condition.
Diagnosing Anemia in Cancer Patients
A doctor will typically use a combination of diagnostic tests to accurately diagnose the cause of anemia in a patient with cancer. These tests help assess the levels of various blood components and identify the underlying factors contributing to anemia. The following tests help the diagnostic process:
Complete Blood Count (CBC)
The numbers of red blood cells, white blood cells, and platelets in the blood are all measured by a complete blood count (CBC), a thorough blood test. Low red blood cell or hemoglobin levels can indicate anemia, while abnormal white blood cell counts may suggest the presence of underlying cancer or another medical condition.
Blood Smear
A blood smear is a laboratory test that examines the shape, size, and overall appearance of red blood cells under a microscope. This test can provide valuable information about the cause of anemia, as certain types of anemia are associated with characteristic changes in red blood cell morphology.
Iron Studies
Iron studies are blood tests that evaluate the body’s iron levels and overall iron metabolism. These tests can assist in determining whether anemia is brought on by a lack of iron or by another factor, such as malignancy or persistent inflammation. Serum iron, total iron-binding capacity (TIBC), and ferritin levels are important factors in iron research.
Vitamin B12 and Folate Levels
Blood tests for vitamin B12 and folate levels can help determine if anemia is due to a deficiency in these essential nutrients. Vitamin B12 and folate are crucial for producing healthy red blood cells, and deficiencies can lead to specific types of anemia, such as megaloblastic or pernicious anemia.
Bone Marrow Biopsy
A bone marrow biopsy involves the removal of a small sample of bone marrow, typically from the hip bone, for laboratory examination. This test may be necessary to determine if cancer or another disease affects the production of red blood cells within the bone marrow, leading to anemia. A bone marrow biopsy can also provide important information about the stage and progression of certain cancers, such as leukemia or lymphoma.
Treatment Options for Anemia Caused by Cancer
Addressing the Underlying Cause
The most effective treatment for anemia caused by cancer is addressing the underlying cause of the anemia. It could entail using a variety of treatments to treat cancer, including surgery, radiation therapy, chemotherapy, immunotherapy, or targeted therapies. By treating cancer, it may be possible to improve the production of red blood cells and alleviate anemia.
Blood Transfusions
Blood transfusions are a common modality of treatment for anemia. Transfusions involve giving a patient donor red blood cells to increase their hemoglobin levels and alleviate symptoms of anemia. It is often a temporary solution, as it does not address the underlying cause of the anemia but can relieve the patient.
Iron Supplements
Iron supplements can help cancer patients with anemia if the underlying cause is iron deficiency. Before taking iron supplements, it’s crucial to speak with a medical practitioner because they can have negative effects and not be suitable for all patients.
Erythropoiesis-Stimulating Agents (ESAs)
Drugs called erythropoiesis-stimulating agents (ESAs) promote the synthesis of red blood cells. Anemia in cancer patients receiving chemotherapy or radiation therapy is occasionally treated with them. However, using ESAs in cancer patients is controversial, as there is a chance of increasing the risks of blood clots. Also, a possible negative impact on cancer treatment outcomes. A healthcare expert should be consulted before deciding whether or not to utilize ESAs.
Vitamin B12 and Folate Supplementation
If vitamin B12 or folate deficiency causes anemia, then supplements can help. This treatment is generally safe and well-tolerated by patients.
Summing it Up
Anemia can be caused by cancer, either directly from the cancer itself or indirectly through other mechanisms. These include blood loss, nutrient deficiencies, or treatment-related side effects. A better understanding of the link between anemia and cancer is essential for healthcare professionals and patients. Prompt diagnosis and appropriate treatment can significantly improve a patient’s quality of life. It may even play a role in the overall outcome of their cancer treatment.
As explored in this article, the relationship between anemia and cancer is multifaceted and complex. Identifying the underlying cause of anemia in a cancer patient is crucial. It enables medical professionals to create a successful treatment strategy. See a medical practitioner if you think that you or a loved one may have cancer-related anemia. You can talk about your symptoms, get a precise diagnosis, and look into your options for possible treatments.
