I went through the same thing, 2x, through out my chemo, and had to have 2 dif. blood transfusions. And they even had me give my self shots in the stomach at home, to bring it up.

I had to have two during treatments as well and felt so much stronger after.

Thanks, all. I really appreciate it. Will just treat as a little bump in the road.

Anemia in People With Cancer
What is anemia?
If your red blood cell count is low, you might have a condition called anemia (uh-nee-me-uh). The red blood cell count is measured with a blood test called a CBC. (CBC stands for complete blood count.)

Anemia means your blood has too little hemoglobin (HE-muh-glo-bin). Hemoglobin is the part of the red blood cell (RBC) that carries the oxygen your body uses.

Doctors often define anemia as a hemoglobin (Hb) level of less than 12 g/dL (grams per deciliter). But many people do not feel much different until their hemoglobin level falls below 11 g/dL, or sometimes even lower. Symptoms of anemia often start slowly, so you may not even notice them at first. But the symptoms get worse as the hemoglobin gets lower. These symptoms can include:

Fast heart beat
Shortness of breath
Trouble breathing when doing things like walking, climbing stairs, or even talking
Dizziness
Chest pain
Swelling in the hands and/or feet
Pale skin, nail beds, mouth and gums
Extreme tiredness (fatigue)
Fatigue, or severe tiredness and weakness, is often the symptom that bothers people most. All of these symptoms can be signs that your body tissues aren’t getting enough oxygen. For more information on fatigue and how to manage it, please see our document called Fatigue in People With Cancer.

What causes anemia?
There are many different causes of anemia in people with cancer. Some of them may have nothing to do with the cancer. The more common causes are:

The cancer itself
Cancer treatment, such as radiation or chemotherapy
Blood loss (this can be slow constant bleeding such as from the intestine or bladder; or fast bleeding, like heavy menstruation or bleeding from a stomach ulcer)
Certain vitamins or minerals missing in a person’s diet
Major organ problems (including severe heart, lung, kidney, or liver disease)
Red blood cells (RBCs) being destroyed by the body before they’re replaced
The body making fewer RBCs
Sickle cell disease or thalassemia (inherited disorders)
A combination of any of these factors
There are also some risk factors that may make you more likely to have anemia. These include:

Platinum-based chemotherapy (this is a certain group of chemo drugs)
Certain tumor types (such as lung or ovary tumors)
Having a low hemoglobin level before you had cancer.
