it is normal to have some fat in your arm pit which can cause some mild "sticking out" of the arm pit area.
are you overweight?
that is good there isn't a spot there.
you can have your GP doctor examine your arm pit and your breast. I bet they will find no evidence of cancer.
let me know if you have questions.
if you are feeling and pressing on the area frequently, this can cause it to be tender.
if you had breast cancer, you would feel a lump in your breast
or an enlarged lymph node in your arm pit.
let your doctor examine these areas if it is worsening your anxiety to do so.
at your age, breast cancer is rare and unlikely.
you are not describing you are feeling a lymph node in your arm pit
one swollen lymph node would not cause your arm pit to swell out
you would be able to feel it with your fingers.
go see your GP doctor.
