I form lumps in my breast they are not a mass and one of them is not a cyst they done ultrasound and mammogram but it still scared me what is it?

Lump: Being scared is a normal feeling. However, do not let the fear take over your life. If no strong family history of breast/ovarian cancer, having a normal mammo and sono are sufficient and they should put your mind on ease. F/u with your md and have annual clinical breast exam and you can also do self breast check.But, if you are at high risk-strong family history-mri need to be considered. D/w md.

See a breast doctor: It is important not to panic, but to take action to get the answer. It sounds like you need a biopsy (sample of the mass) in order to find out what this is. Contact your doctor for a referral to a breast specialist. Most biopsies will come back as noncancerous.

Can't tell based: on limited information, but if you look at the bottom of the report, there will be a BIRADS category for the lesion, which is the radiologist's level of suspicion. BIRADS 2 is benign, 3 is probably benign(less than 2% chance of cancer), 4 is suspicious(about 30%), and 5 is highly suspicious(about 75% or more).
