EXAMPLES OF DIFFERENT CANCER PATIENT SCENARIOS-
HOW PET IMAGING CAN HELP
LUNG CANCER

During a routine physical examination your doctor tells you that
the routine chest x-ray showed a lesion in your right lung and it’s
not sure whether it is benign or malignant. A PET scan will show whether
the lesion is benign or malignant. If the lesion is benign, you can
be monitored over time with chest x-rays to detect any changes in
the lesion. If the lesion is found to be malignant by PET scan, the
same PET scan can determine if the cancer has spread. The PET scan
will also show if surgery or some other type of therapy is needed.
RECURRENT COLORECTAL CANCER
You have a history of colon cancer. Your doctor tells you that your
serum CEA levels have increased. A CT scan of your abdomen and pelvis
is negative. A PET scan can determine whether there is a recurrence
of the colon cancer and if it has spread. The PET scan can also help
determine what treatment would be indicated.
BREAST CANCER
You have a history of breast cancer and have recently developed symptoms
that worry you. A PET scan can determine whether there is a recurrence
of the cancer and the extent of its spread. One PET scan can image
most of the body eliminating the need for several other scans to be
done.
LYMPHOMA
You have been diagnosed with a lymphoma. A PET scan can determine
the extent of the disease. A follow up PET scan can determine the
success of treatment of this disease.
RECURRENT MELANOMA
You have a history of malignant melanoma. Recently you develop pain
in your abdomen. It is possible that the melanoma has spread to your
abdominal cavity. A PET scan can determine whether the cancer has
recurred and spread. It can also help determine what treatment you
should receive.
THE HEART
You have been told that your heart is so damaged that you need a
heart transplant. A PET scan can determine whether the heart muscle
is damaged beyond repair or could be salvaged by bypass surgery.
THE BRAIN
Your doctor suspects that you have early onset of Alzheimer’s disease.
A PET scan can diagnose this condition in its early stages so that
aggressive treatment can occur. A PET scan can also find areas of
seizure activity that could be removed by surgery.
