<s>[INST] hi i have a lump in my right breast and i also hav thyroid problem,so it had been around a month that i was taking thyronorm,primosa(2 times a day) and 1 more hormonal prob medicine. And now one week ago i had a convulsion fit.Was it because of too much medicines. i had no other tensions.Now the medicines have been stopped.I am a little confused plz explain. [/INST] Hello!Thank you for the query.Breast lump can appear to some hormonal problems. But this is the last reason which should be considered. In first row you need to rule out a breast cancer. Please do not wait with it. Consult gynecologist, have breast and armpit examination and ultrasound. If the lump will be confirmed biopsy of it should be done.Hope this will help.Regards. </s>
