My right breast is swelling rapidly. It is hot to the touch. Should I go to the er mammo and US this week lump found undetermined benign or malignant ?

Are malignant breast lumps usually movable?

I'm 46 and had a core biopsy for a large breast lump. The diagnosis was fibroadenoma. Will it ever turn malignant?

NO: Generally fibroadenomas are benign tumors that predcominantly occur in younger females of childbearing age. In and of themselves, they do not transform into malignant lesions. This is determined by other factors such as family history, genetic testing, calcfications, cellular atypia, etc. That will be a part of a complete hsitory and physical examination, . ...Read more

Lump between breasts, history of melanoma, malignant mole removed from directly across the location of the lump. Any chance it's just a cyst?

Wrong question: Please forgive my frankness. The only question you need to ask is, "Could it be CANCER?" With your cancer history, and the fact that this is a dominant mass where there's possibly breast tissue, you need to get seen. Period. Pick up the phone now. To be brave, act brave. We'll be thinking of you, and if it's benign / nothing / a lipoma / a cyst, you're a stronger and more skilled person. ...Read more
