Suspicious lump

I went to the hospital after a lump was found in my left breast. Ive had the mammogram & scan inc a core biopsy & now have an appointment to revisit hospital, just one week later. My question is, do you normally have to go back for results or is this a bad sign. I wasnt sure if you were usually called back if it is cancer or do they call you back wether its cancer or not, as im now somewhat worried, thanks all. ️
