It's very important that fluid does not accumulate around the surgical site after mastectomy or breast reconstruction. Historically, these more complex plastic surgery procedures have required drains. The fluid may be measured at least once a day to ensure that drainage is decreasing as expected. Trust that, if you do need drains, your doctor will be motivated to remove them as soon as it is safe to do so. Also, if it is expected that you'll need drains, you will be fully informed well ahead of time regarding what to expect, how to care for them, and when to contact the office.
