A British survivor of testicular cancer is alive due to a relatively unknown method of detection: a pregnancy test.
Cambridgeshire's Byron Geldard, 18 at the time, visited his doctor because of an ache in his side, the Telegraph reports.
The boy was told he had nothing to worry about, however, as his doctor attributed the pain to exercise.
He returned to the doctor a few months later, following a trip to the Greek island of Kavos with some friends.
Geldard had developed a lump on his side and underwent an ultrasound exam immediately after this visit.
Doctors found a tumor had spread to Geldard's lungs and abdomen, but they weren't positive which type of cancer he had.
Geldard told the Telegraph,
Geldard was soon contacted by the Teenage Cancer Trust unit in Cambridge and told to provide a urine sample for a pregnancy test.
According to the Telegraph, an emerging placenta in a woman creates the same hormone yielded by a disease that afflicts tens of thousands of men worldwide.
A positive pregnancy test led to the teen's diagnosis of stage four testicular cancer.
A spokeswoman for the Teenage Cancer Trust said these tests have been used to diagnose testicular cancer for roughly six years.
Geldard began chemotherapy the day after his diagnosis.
The hormone had been largely present in the beginning of his treatment, but his chemotherapy proved to be working.
Geldard had the significantly diminished tumor in his abdomen, one testicle and the lymph nodes behind his stomach removed last December.
A test revealed him to be cancer free the next month.
Geldard, now 19, has since become an ambassador for the Teenager Cancer Trust and will be speaking to students about testicular cancer.
He is also crafting a standup comedy show to spread awareness about the disease.
