My husband has found a mass in his right groin , seems to be fixed. he says it has not increased in size since found 2 day ago? ideas? or concerns?

Mass in groin: A fixed mass in the groin can be an enlarged lymph node, a cyst or a hernia. If it is tender or painful he should see his physician or go to an urgent care to have it evaluated. Severe pain can indicate an incarcerated hernia which is an emergency.

Hernia or Lymph Node: Most common masses in the groin are an inguinal hernia or lymph node. If it is painful and increases with straining it's most likely a hernia which should be fixed surgically. If it's a lymph node and does not improve in one week he should see his family doctor.
