I have bony lump in my groin and have had this for 3 years. Originally it was diagnosed as a groin strain and further investigations and a MRI scan showed it to be on my pubic tubicle of aprox 2.5 cm and probably as a result of repetitive aducter exercises. I was told it may get bigger. I feel well but the lump seems to be getting larger maybe 4cm it dosen t hurt but I sometimes get a sensation that its pressing on nerves at the top of my leg so I can sense it touching other areas I am a female of 45 years 5 ft 9 and aprox 11 stone. What is the likely hood that this is something sinister and is there a quick blood test to show if it is rather than further scans etc
