A CA test may be used to monitor certain cancers during and after treatment. In some cases, a CA test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease. A CA test isn't accurate enough to use for ovarian cancer screening in general because many noncancerous conditions can increase the CA level. Many different conditions can cause an increase in CA , including normal conditions, such as menstruation, and noncancerous conditions, such as uterine fibroids.
Breast Cancer Tumor Marker Tests
Tumor marker - Wikipedia
Tumour markers are substances that are made by cancer cells or by normal cells in response to cancer. Most people have these substances at a low level in their blood, but the amount of each marker can increase, sometimes a lot, when there is cancer in the body. Some tumour markers are specific to one type of cancer, while others may be present in many different types of cancer. Tumour marker tests are usually done in a lab or hospital. A lab technologist will take a sample of your blood. The blood sample is then analyzed using special machines. If a tumour marker is being used to see if the treatment is working or to see if the cancer has come back, it will be measured in many samples taken over a period of time called serial measurements.

Evidence increasingly points to chronic stress as a factor that might contribute to cancer causation and influence survival. Determining whether chronic stress is related to cancer in some way, let alone how that relationship plays out in the body, continues to challenge researchers. Ditto for the range of issues that may influence the course of cancer once it has occurred. That said, experts in the field of psycho-oncology, which concerns itself with the psychological, behavioral, and social factors that may affect cancer, say that a growing body of literature suggests that stress does play a role in cancer causation and recovery.
A tumor marker is a substance that is made by the body because a cancer is present, or it can be made by the cancer itself. Some of these markers are specific to one cancer. Some are seen in several types of cancer. The markers can be found in the blood, urine, or tissues.
