You may have to gather your mammogram films, biopsy slides, pathology report, and proposed treatment plan. Usually it is not a problem to take several weeks to get a second opinion. In most cases, the delay in starting treatment will not make treatment less effective. To make sure, you should discuss this delay with your doctor.
