Strange, my left breast “vibrates” every so often, sort of like a cell phone that's on vibrate! For the last three days my left breast has this strange vibration. At first I thought I was imagining it but it continues! It doesn't hurt… just feels weird. Could it be a symptom of breast cancer? — Joni

reasonable possibilities:

Fasciculation – a tiny twitching of the muscles, this can be the result of motor neuron disease. But it can also occur in healthy people, the result of too much caffeine, exercise, fatigue, or stress.

Contractions of the tiny muscles surrounding the milk ducts in the breast. Cause unknown, though the theory is they could be due to a temporarily blocked duct.

Spasms of the tiny blood vessels in the breast. Again, cause unknown.

Martee L. Hensley, M.D., a medical oncologist at Memorial Sloan-Kettering Cancer Center in New York, writes about breast vibration as follows:

“While feeling vibrations in the breast is a rather uncommon complaint, these sensations have not been associated with any serious condition. It is sometimes hard to pinpoint an exact cause… [but it’s] highly unlikely that there is cause for alarm, whatever the specific explanation.

“Some possible causes may include muscle twitching – breast tissue does have a small amount of muscle in it, and these muscles may involuntarily contract, like a muscle spasm you might feel in a larger muscle. The chest-wall muscles behind the breast tissue might also contract or spasm.”
