A study involving Swedish men implies that men with prostate cancer are two and a half times more liable to suffer a blood clot as other males.

The risk is highest for men receiving hormone treatment for their cancer and they are more likely to suffer a blood clot than men without cancer.

According to the article in Lancet Oncology, they were also twice as likely to have a clot in the lung that can prove lethal.

Doctors should be aware of the heightened risk that is believed to be caused by an amalgamation of the cancer and its treatment and other conditions the men might have had.

Mieke Van Hemelrijck from King’s College London analyzed more than 70,000 Swedish men with prostate cancer.

Dr. Helen Rippon, Head of Research Management at The Prostate Cancer Charity, said that a link has been discovered between hormone therapy and blood clots in these men but that does not essentially mean that the treatment lead to the clots.

She said that other factors might be responsible and added that men on hormone therapy should not get overly worried as a consequence of this research. Hormone therapy has apparent, verified clinical benefits and can out off advanced prostate cancer for months or even years.

"We urge any man on hormone therapy who is concerned that he might be at greater risk of blood clots to speak to his specialist before making any decisions about whether to continue with the treatment", she concluded.
