Stein102, whether a partial or complete rupture of the pec major both need to be investigated and potentially repaired. Most Orthopaedic Surgeons would recommend this considering you desire to continue lifting. Those tears whether partial or complete that are located closer to the musculotendinous junction or humeral attachment are more likely to be successful if repair is achieved earlier rather than later.

I would encourage you to advice regarding an Wikipedia reference-linkMRI to ascertain the extent and location of the tear before returning to lifting or forceful adducting activities.

I have seen partial tears that haven't bruised up and were difficult to observe even when stress testing.

I also agree with physiointhesand regarding the cuff.

Good Luck!
