A relative of mine was shot 20 years ago in the occipital lobe. Only part of the bullet was removed as it was thought to be an unnecessary risk to remove the remaining part; the specialists assured that the remaining piece would not cause any damage.
Although, till that day, there hasn't been any effect clearly linked to that incident, I am concerned that the remaining piece, would in the future cause some damage, I'm also concerned about the lead exposure from the bullet.
Any advice or thoughts would be immensely appreciated.
