Can cancer patients eat folic acid?

Folic

acid is a water-soluble vitamin that is essential for cell growth and development, especially in DNA synthesis and cell division. For cancer patients, folic acid supplementation is beneficial to increase white blood cell count, improve immune function, and reduce side effects of chemotherapy drugs, such as bone marrow suppression and anemia. However, folic acid supplementation is not the main treatment for cancer and should not be over-relied upon. Cancer treatment usually includes surgery, chemotherapy, radiotherapy and immunotherapy.
