Impact of multiple sclerosis on breast cancer survival

Takeaway

  • Women with multiple sclerosis (MS) have lower survival following breast cancer diagnosis than women without MS.

Why this matters

  • Cancer is a leading cause of death among patients with MS, with female breast cancer being 1 of the 3 most common incident cancers; yet, few studies have evaluated survival after breast cancer diagnosis in MS.

  • Results from this study may inform women with MS and their healthcare providers concerning survival risks and potentially impact treatment course.
