Ultrasound scan of breast found 4 lesions, they wasn’t worried about 3 but one has been biopsied. Should I be worried?

I noticed a small lump and went to gp she said it felt cystic and mobile, put me in the 2 week pathway. Went today they examined me, gave me a mammogram and ultrasound. Th found 3 further lesions, they gave me biopsy on the known lump and lymph nodes, went back to see the consultant and he said the other 3 were fine but the original one looked suspicious and I have to wait for an appt in 2 weeks - I’m frightened really frightened - does this mean cancer
