Q. I was diagnosed with non-small cell lung cancer and am receiving chemotherapy. I've had two colds within a three-week period and also a low level of hemoglobin in my blood (the doctor has recommended erythropoietin treatments). Could these issues be diet related?
Chemotherapy for either small cell or non-small cell lung cancer tends to be fairly aggressive and can produce some difficult side effects. While chemotherapy is focused on destroying lung cancer cells it can also interferes with the production of the three types of blood cells: red blood cells, white blood cells, and platelets. Normally, just before you start a chemotherapy session, your doctor arranges for you to have blood tests to determine the effect the chemotherapy is having on your blood cells. Low counts of any of these cells may prompt either a change in dosage or frequency of treatment, or a need to take medication that can stimulate bone marrow production of the blood cells.
Your colds may be due to the chemotherapy’s suppression of the bone marrow’s production of white blood cells, which are the body’s infection fighters. If your doctor feels that your white cell count has significantly decreased, he or she may consider putting you on a medication for this condition. Ask your doctor whether this might be a possibility.
Similarly, the low levels of hemoglobin you mention may be due to low red blood cell counts caused by chemotherapy. Red blood cells carry oxygen and iron to provide the body with components necessary for energy. Red blood cells are an important factor in maintaining energy levels in our bodies and too few of them can result in fatigue and anemia. It sounds like your doctor believes an erythropoietin-type drug might be helpful in boosting your red blood cell count. While extreme low red blood cell counts are not normally related to diet, you might also want to ask your doctor for a referral to a dietitian who works with cancer patients to develop a meal plan that would increase your dietary intake of iron and help you maintain a healthy weight.
