Heart and lung tests

Some cancer treatments can damage your heart

and lungs. Thus, your doctors will test how well your

heart and lungs work to plan treatment. If they aren’t

working well, you may receive other treatment.

Ejection fraction

An echocardiogram is an imaging test of your heart.

It uses sound waves (ultrasound) to make pictures.

During this test, you will be lying down. Small patches

will be placed on your chest to track your heartbeat.

Next, a probe with gel on its tip will be slid across part

of your bare chest. A picture of your beating heart

will be seen at once on a screen. The pictures will be

recorded for future viewing.

An echocardiogram shows how much blood is

pumped out of the left side of your heart. The amount

of pumped blood is called the ejection fraction. It

is a measure of heart failure. A normal amount of

pumped blood is between 55 and 70 percent. High or

low ejection fraction may prevent you from receiving

some types of chemotherapy.

Pulmonary function tests

Pulmonary function tests reveal how well your lungs

work. Three tests are often used. A common side

effect of these tests is shortness of breath.

• Spirometry involves blowing into a tube to

measure how much air and how fast you

breathe.

• A gas diffusion test involves breathing in a

harmless gas and measuring how much you

breathe out. It tells how much oxygen travels

from your lungs into your blood.

• Body plethysmograph involves sitting in a

small room and breathing into a tube. This test

measures how much air your lungs can hold

and how much air is left in your lungs after

you exhale.

Vaccines

Your spleen is part of your lymphatic system. Your

chances of getting an infection are high if your spleen

is treated with radiation. In this case, get vaccinated

before treatment for H-flu (

H

aemophilus in

flu

enzae),

pneumococcal, and meningococcal infections. H-flu

does not cause the common flu. It causes other

diseases like bacterial meningitis. Not all vaccines

are safe for people with cancer. Talk with your doctor

about other vaccinations before getting them.
