Esophageal cancer can contribute to lower hemoglobin levels, a condition known as anemia, through several mechanisms:
-
Bleeding: Tumors in the esophagus may cause bleeding, either through ulceration of the tumor or erosion into nearby blood vessels. This can lead to a loss of blood and subsequent decrease in hemoglobin levels.
-
Nutritional deficiencies: Cancer can lead to difficulties with eating and swallowing, which may result in inadequate nutritional intake. Deficiencies in essential nutrients such as iron, vitamin B12, or folate can contribute to the development of anemia.
-
Bone marrow involvement: In advanced cases, cancer cells may infiltrate the bone marrow, which can impair the production of red blood cells and lead to lower hemoglobin levels.
-
Chronic disease: Cancer can also lead to anemia of chronic disease, where the body’s response to illness affects red blood cell production and function.
If someone is experiencing symptoms associated with esophageal cancer or anemia, it is important to seek medical evaluation and management.
