Question: Why is hemoglobin low in lung cancer?

Can lung cancer cause low hemoglobin levels?

Cancer-related or cancer treatment–related anemia occurs frequently in patients with lung cancer,2, 3 with one comprehensive review reporting incidences of anemia (hemoglobin [Hb] ≤12 g/dL) and severe anemia (Hb <8 g/dL) as high as 100% and 55%, respectively, in patients with lung cancer receiving chemotherapy.

Does lung cancer affect hemoglobin?

Background and objective: Anemia is commonly observed in lung cancer (LC). Hemoglobin levels at the time of diagnosis could be considered a prognostic indicator in patients with LC.

Why does cancer cause low hemoglobin?

What causes anemia in cancer patients? Anemia is a common condition of cancer patients. This is because cancers cause inflammation that decrease red blood cell production. In addition, many chemotherapies are myelosuppressive, meaning they slow down the production of new blood cells by the bone marrow.

Can you be anemic with lung cancer?

Anemia has a high prevalence in patients with lung cancer. Its frequency and severity depend on tumor stage, duration of disease, and previous and current treatment. Anemia affects the health-related quality of life and impacts prognosis and outcome of therapy.
