This isn\’t entirely unheard of. Rare, but not never.
Gavin Hyatt, 30, explained that the lump forced its way out after lying inside his abdomen since he was born.
Medics said the 4cm growth was a parasitic twin that died in the womb early in their mother\’s pregnancy.
Mr Hyatt, a former firefighter, from Witney, Oxfordshire, said: "Four hospital doctors had previously examined me and were all puzzled by the lump.
"Some thought it was a cyst, others an in-grown hair.
"Then one said it could be my undeveloped identical twin that I absorbed at a very early stage. I feel absolutely fine now but it has not sunk in yet that I could have had a twin brother. …. I haven\’t told many people. I feel like a bit of a freak."
Odd and rare, perhaps, but perhaps not a freak.
I have him in a jar at home and I call him little Gav.
That makes you a freak, yes.
