A man has been forced to have his penis removed five years after it was injected with olive oil to make it bigger.
The unnamed 50-year-old was admitted to hospital after suffering a cut to his penis some six months ago. He did not seek medical help and the cut became infected, swelling his genitals "to the size of a coconut."
When he finally saw a doctor, it was discovered he had cancer that required his penis to be amputated, The Bangkok Post reported.
Police Captain Dr Surat Kittisup-porn of Thailand's Police General Hospital told reporters: "He was ashamed to visit a doctor, but the pain and infection grew so he had no choice."
It is not clear if the olive oil injection contributed to the infection, although the procedure has been reported to cause swelling, inflammation and abscesses.
According to the Herald Sun, black market olive oil injections are common in Thailand, as are complications, with the hospital apparently receiving around 40 patients a month concerned about side-effects.
Hospital spokesman Sirikul Jiaranaikhajorn told AFP: "This is the biggest (genital) surgery we have ever done as we found cancer," adding the majority of patients they treat tend to suffer infections and there is no evidence the procedure causes cancer.
She added: "It only brings bad results - people misunderstand (that it works).
Tragically, the man's cancer has spread to his testicles and abdomen and surgeons fear it will spread again in the future.
