Is iron Linked to cancer?

In addition, heme iron, mainly found in red meat, can be involved in carcinogenesis by acting as a nitrosating agent (11), forming N-nitroso compounds that are known carcinogens (12). This could explain the association between red meat intake, the main source of heme iron, and certain types of cancer (13).

Why does cancer cause low iron?

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 low iron cause anemia without cancer?

Lymphoma in the bone marrow

If you have lymphoma cells in your bone marrow, they take up space that is normally used to make healthy blood cells. This can lower the number of red blood cells your bone marrow makes, leading to anaemia.

Can a blood test reveal lymphoma?

The doctor also might order blood tests to look for signs of infection or other problems. Blood tests aren't used to diagnose lymphoma, though. If the doctor suspects that lymphoma might be causing your symptoms, they might recommend a biopsy of a swollen lymph node or other affected area.
