Semen can promote cervical cancer

The increase in cervical cancer and uterus can be caused by a hormone-like molecule in semen, according to the Medical Research Council (MRC).

Molecules (prostaglandins) present in semen (BBC Photo) Scientists from MRC have discovered abnormal levels of prostaglandins that increase tumor growth. They believe that women with cancer should also ask their husbands to carry condoms when having sex.

However, one oncologist says the risk of unprotected intercourse for this condition is 'negligible'.

Prostaglandins occur naturally in female reproductive organs cells. Its role is to regulate cell growth and order the uterus to thicken or thin in the monthly menstrual cycle. But the concentration of prostaglandins in semen is 1,000 times higher.

Cervical and uterine tumor cells have prostaglandin receptors on their surfaces. Scientists at the MRC have exposed cancer tissue to prostaglandins. They found that the prostaglandin flow in semen increased normal signaling levels between cells. This cumulative signal level leads to an increase in tumor growth.

The researchers say the finding helps develop a therapy that prevents prostaglandins from coming into contact with tumor cell receptors, and thus slowing the progress of cancer.
