Blood tests can predict breast cancer - the media is overstated

Release date: 2015-04-29

Today's headlines forecast a new "simple blood test," claiming that the test can predict whether a woman will have breast cancer in the future. This news sounds amazing.

However, you may think that this seems to be too good, not really, you will think so.

In this study, you can find it in Metabolomics, where researchers have discovered a blood test that tests the chemicals and molecules in women's blood. This is called a "metabolic profile" and tells the doctor that the woman is Will you get breast cancer in the next seven years?

Although this method is very interesting, the study is still in its early stages, only tracking data from about 800 Danish women. Before anyone says that blood testing is a sufficiently accurate and sensitive method to reliably identify high-risk women with breast cancer, further research is needed, including research on a larger number of female populations. .

And, crucially, this work needs to prove that this approach does not erroneously identify women who are at high risk for breast cancer.

Therefore, it is still too early to say that doctors can use blood testing to predict which women will have breast cancer.

Moreover, the news agency also reported the opposite statement, there is currently not enough evidence to prove that the blood test method can "replace the mammogram", the test results can not help the custom screening, or for the mammogram Check for supplements.

Importantly, in this published article, the researchers themselves said that they still need to do more work to fully understand the implications of blood test results. More work needs to be done for women in other countries, other eating habits, lifestyles, medications and customs.

This is not to say that this blood test method will not have any results in the future. Tumor cells use nutrients to have enough energy to grow, and the changes produced by this way of tumor cells are an attractive and growing area of ​​research. Scientists are delving into whether these changes can be used to detect disease early, monitor treatment response and develop new treatments. But these are still early.

At present, this is an interesting work that may lead to the development of new detection methods in the future. This test may one day help doctors diagnose women at high risk of developing breast cancer.

However, it is still too early to say so.
