Lab tests for breast cancer may also be used to:. For people who are at high risk for breast cancer, such as a person who has a personal or family history of the disease, a genetic test may be recommended. The test will look for:.
A simple blood test that detects tumor cells circulating in the blood shows promise as a new way to predict high or low risk of a breast cancer relapse. We found that in women who were cancer-free five years after diagnosis, about 5 percent had a positive CTC test," said lead researcher Joseph A. Sparano continued.
If you are diagnosed with breast cancer, your doctor may order additional lab tests to assist with prognosis. Results from these tests can provide insight into which cancer treatment options may be most effective for you. Jan was diagnosed with Stage 4 breast cancer in June after undergoing a routine bone scan for an unrelated injury. A wife and mother, Jan described her initial diagnosis as a complete shock.
A simple blood test could help to detect breast cancer relapse up to two years earlier than imaging in patients with early-stage breast cancer. In a small study, carried out by the University of Leicester and Imperial College London and funded by Cancer Research UK, researchers showed that the blood test was able to detect 89 per cent of all relapses, on average 8. Breast cancer is the second leading cause of cancer death in women.
You may not need them. And the risks may be greater than the benefits. Imaging tests, such as CT, PET, and bone scans, take pictures to help find out if the cancer has spread in your body.

A new blood test looking at immune cell activity may be able to predict the likelihood of breast cancer recurrence. Photo credit: Getty royalty-free. A newly-developed blood test may be able to predict if people with breast cancer are likely to relapse at the point they are initially diagnosed by looking at markers of immune system function.
You can eat and drink normally before most blood tests. Your doctor will tell you if you need to stop eating and drinking beforehand and for how long. This is called fasting.
