Is there a positive correlation between having MS and cancer? Many people I know with MS also have/had cancer (including my self - Stage IV Breast).
Because an occurrence of breast cancer makes a patient more susceptible to future cancers, I am interested in knowing if there is a more elevated risk due to also having MS.
The verdict is still out on whether there is an elevated risk of cancer in Multiple Sclerosis patients. Most studies have shown no evidence of an increased risk of cancer but several outliers have shown a decreased or increased risk. It seems unlikely that an increased risk of cancer is associated with MS based on current available evidence. However, several treatments for MS may increase the risk of certain skin cancers and cancer of bone marrow derived cells (lymphomas and leukemias) and one treatment may increase the risk of bladder cancer.
