Its good that you had observed that there's a lump in your breast. You were knowing since last 1 year so you might also be observing the lump. If the lump has increased in size recently or its consistency has changed, so the skin over the lump is showing changes like orange peel, than you need to really worry. But if the lump has not shown any changes in last 1 year than there is possibility that the lump is not cancer. So fix an appointment with your dcotor for biopsy
& than after the report it will be clear whether it is cancer or not,
Wish you good health, take care.
