I decided to do a full health screening and they found a lump in my left breast, the doctor ask me to do another ultrasound in yearly basis, previously i found a lump in my
thyroid, did ultrasound and doctor claimed the lump is benign and follow up after 6month, i decided to remove half thyroid and it turned to be cancerous. So is it advisable to do a second ultrasound just to be sure the lump in my breast is really benign?
