At your age with no personal or family history to suspect hereditary breast cancer (e.g. BRCA gene mutations that can be passed from parent to child) the chances of your lump being cancerous is really not very high.
That said, any breast lump should be checked by a doctor to be certain.
Besides a physical examination, imaging of the lump will be performed to better inform us if the lump needs to be removed. A needle biopsy (sampling of tissue from the lump) may also be offered.
Most experienced breast surgeons would not suggest that all lumps need to be removed. The decision is best made after a consultation.
