Noticed a lump that is movable,on the left side of my chest, I am a 62 yr old male, had open heart surgery about 5 yrs ago, this area has always been a little numb.  Is there anything you can tell me, besides go get it checked, which is what I intend to do.
Hi. Thanks for your query. If this movable lump is not in the line of a scar of your heart surgery, this can be a sebaceous cyst as the most probable cause. If it is on the scar-this is called an inclusion cyst And the treatment of both the things is same. If the lump is not symptomatic, you can wait and watch. Discuss this lump when you are visiting your Doctor and ask about removal.
