A new study has found that men with prostate cancer have an increased risk of developing blood clots, especially if they’re undergoing hormone therapy.

According to HealthDay News, researchers analyzed data from Sweden’s National Prostate Cancer Register, which includes 96 percent of all prostate cancer cases in that country. The participants were divided into three groups – those receiving endocrine or hormone therapy, those receiving surgery and/or radiation and those who were simply being watched.

They found that men taking hormone therapy had a 2.48 increased risk of developing a blood clot and almost double the chance of a pulmonary embolism, compared to men without prostate cancer. Those who were treated with surgery had a 73 percent increased risk of blood clots and those who were being monitored had a 27 percent increased risk of blood clots. None had an increased risk of arterial embolism, which is when clots block an artery.

"We have known for decades that cancer patients have a greater risk of blood clots, but it hasn’t been as well-defined in the prostate cancer population," said Dr. Steven Clinton, director of prostate and genitourinary oncology at The Ohio State University Comprehensive Cancer Center – James Cancer Hospital and Solove Research Institute in Columbus.

Despite the findings, the study’s authors say doctors should not change the way men with this type of tumor are treated.
