Hemoglobin (often abbreviated as "HemoG") is a protein in red blood cells responsible for transporting oxygen throughout the body. While hemoglobin itself is not directly linked to cancer, there are several important aspects of its relationship with cancer that are worth noting:
Many cancer patients experience anemia, which is a condition characterized by low levels of hemoglobin. This can be due to various factors, including the cancer itself, chemotherapy, or nutritional deficiencies.
Tumors often have regions of low oxygen (hypoxia) due to inadequate blood supply. Hypoxia can promote tumor progression, metastasis, and resistance to therapy. Hemoglobin's role in oxygen transport makes it a critical factor in the tumor microenvironment, as oxygen levels can influence cancer cell behavior.
Changes in hemoglobin levels or the presence of specific hemoglobin variants may serve as potential biomarkers for certain cancers.
