I finally have a date to have blood work done to see where my tumor markers are. Next Tuesday I will have my blood work done and then it will be a waiting game. To be honest, I am torn about seeing my results. On one hand, I am excited to see the results because I feel we have worked really hard with all the drastic changes we have made with our lifestyle, and the amount of treatments I have been doing. On the other, I have to admit that there is a little fear in the back of my mind whispering to me that everything won’t be ok. This is where the battle lies. In the mind. It is a daily fight to remain positive and focused. But fight I will! Please continue to pray for our family. Pray for peace in this time as we await the results of the blood work.
Thanks for being a part of our journey.
To learn more about tumor markers, check out below the info I found on the cancer.gov website. Thanks.
What are tumor markers?
Tumor markers are substances that are produced by cancer or by other cells of the body in response to cancer or certain benign (noncancerous) conditions. Most tumor markers are made by normal cells as well as by cancer cells; however, they are produced at much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumor tissue, or other tissues or bodily fluids of some patients with cancer. Most tumor markers are proteins. However, more recently, patterns of gene expression and changes to DNA have also begun to be used as tumor markers.
Many different tumor markers have been characterized and are in clinical use. Some are associated with only one type of cancer, whereas others are associated with two or more cancer types. No “universal” tumor marker that can detect any type of cancer has been found.
There are some limitations to the use of tumor markers. Sometimes, noncancerous conditions can cause the levels of certain tumor markers to increase. In addition, not everyone with a particular type of cancer will have a higher level of a tumor marker associated with that cancer. Moreover, tumor markers have not been identified for every type of cancer.
How are tumor markers used in cancer care?
Tumor markers are used to help detect, diagnose, and manage some types of cancer. Although an elevated level of a tumor marker may suggest the presence of cancer, this alone is not enough to diagnose cancer. Therefore, measurements of tumor markers are usually combined with other tests, such as biopsies, to diagnose cancer.
Tumor marker levels may be measured before treatment to help doctors plan the appropriate therapy. In some types of cancer, the level of a tumor marker reflects the stage (extent) of the disease and/or the patient’s prognosis (likely outcome or course of disease). More information about staging is available in the NCI fact sheet Cancer Staging.
Tumor markers may also be measured periodically during cancer therapy. A decrease in the level of a tumor marker or a return to the marker’s normal level may indicate that the cancer is responding to treatment, whereas no change or an increase may indicate that the cancer is not responding.
Tumor markers may also be measured after treatment has ended to check for recurrence (the return of cancer).
How are tumor markers measured?
A doctor takes a sample of tumor tissue or bodily fluid and sends it to a laboratory, where various methods are used to measure the level of the tumor marker.
If the tumor marker is being used to determine whether treatment is working or whether there is a recurrence, the marker’s level will be measured in multiple samples taken over time. Usually these “serial measurements,” which show whether the level of a marker is increasing, staying the same, or decreasing, are more meaningful than a single measurement.
