Study testosterone linked to cancer

UNITED STATES (OBSERVATORY NEWS) — British doctors have linked high testosterone levels to the risk of developing cancer. However, its level affects tumor development in men and women differently.

A team from the Universities of Cambridge and Exeter discovered that testosterone levels influence the development of malignant tumors and diabetes, the study published on MedicalXpress says.

According to its authors, who have conducted the genetic analysis of more than 425,000 blood samples from men and women, the high level of this sex hormone is not a consequence of the disease but one of its causes . Concretely, this promotes the development of breast and prostate cancer.

Risks

It has been shown that an increased level of testosterone in women increases the risk of developing type 2 diabetes by 37%. In men , this probability is reduced by 14%.

Another danger of high testosterone levels in women is an increased risk of polycystic ovarian disease and endometriosis, the study found.

Conclusions and projects

“Methods to reduce testosterone levels are widely used today to treat prostate cancer, but there was no certainty that they could be used to prevent” the disease, found the one of the study’s authors, John Perry. “Now we understand more clearly the risks and benefits of hormone therapy in this area.”

The scientists said they had not yet been able to link testosterone levels to other conditions, such as cardiovascular disease, but that they planned to conduct such a study.
