Blood Calcium Levels Predict Prostate Cancer
Prostate cancer can now be predicted in a new way. Men with high levels of calcium in blood are at higher risk for developing fatal form of prostate cancer. Test allows to predict prostate cancer a decade before it comes.
A study by US researchers examined 2814 men who had taken blood tests to identify calcium levels. Those men with higher levels of blood calcium had a 2.68 times higher risk of suffering a fatal form of prostate cancer, but cancer came only a decade after a test was performed. Calcium level were no way linked to nonfatal forms of disease.
Researchers are now looking at the reasons of the prostate cancer and blood calcium link. There is a hypothesis that parathyroid hormone, which is actually responsible for controlling blood calcium levels in blood, can define prostate cancer risk. There have been other researches linking calcium levels, parathyroid hormone, and prostate cancer to each other.
However, this is just a possible version and needs to be proved, otherwise, if calcium levels themselves are risk predictors, it will be very easy to cut the risk of prostate cancer. Currently there are approved medications for lowering calcium levels, and if the link is approved, it will be easy to delay prostate cancer. It is known that calcium in diet and in blood are not linked to each other, which means that men extra calcium as nutrition will not reduce prostate cancer risk.
The study can lead to simple strategies to lower and predict the prostate cancer risk in men.
"If we can show that men with high-normal serum calcium really are three times as likely to develop a fatal prostate cancer, we might be able to alter this risk with existing drugs that have been proven to be very safe," study researcher Gary G. Schwartz, PhD, of Wake Forest University Baptist Medical Center, tells WebMD.
There are about 780,000 who are prostate cancer diagnosed and 250,000 patients who die each year. Researchers are looking for ways to predict the risk of prostate cancer to treat it as early as possible. If this study is approved, doctors will be able to save lives and delay the disease.
