A new study has found some cancers to be slightly more frequent in people with multiple sclerosis (MS) than in people without MS. The study is published in the October 9, 2024, online issue of Neurology(r), the medical journal of the American Academy of Neurology. Types of cancers found to have a small increased risk include bladder, brain and cervical cancers. The study does not prove that MS increases a person’s risk of cancer. It only shows an association.
