found lump/ fatty tissue or something

hi all

im new going to gp tomorrow 

woke up this morning while getting dressed i felt a lump , trying not to panic and being on the plumb side i tried to feel like dr showed me ... still felt it even over my t shirt , also slight pain more like niggle 

next month am 50 , i also suffer from antiphsolipid symdrome and warfarin for life only found that out coz i bit of blood clot went to my little finger hospital did scan found clot in my right subclavin artery 

so  i dont have usual symtoms 

also awaiting awaiting surgeon for my spine ( 3 prolaspe disc , 2 herinated disc , teathered spine sord , and spine bifida occulta ) 

closet thing to family history are 1st cousins 

i am  scared mind is thinking and yes dr google dont help 

is it normal to have mild pain with lumps in breast ?
