99.999999% bad, yes, but not ALL bad...lower cancer risk in people with MS was already known before this study, but more evidence is always nice...
Multiple sclerosis associated with lower cancer risk
March 30, 2009 - A new study shows that people with multiple sclerosis may be at a lower risk for cancer overall, but at a higher risk of developing certain types of cancer, such as brain tumors and bladder cancer. The study is published in the March 31, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.
Researchers looked at the medical records of 20,000 people with multiple sclerosis and 204,000 people without the diagnosis. After 35 years, they found that the people with MS had a decreased overall risk of cancer by 10 percent compared to people who did not have the disease. The result was more pronounced in women. However, for people with MS the risk for certain cancers, such as brain tumors and bladder and other urinary organ cancers, increased by up to 44 percent compared to people without MS.
Scientists also evaluated the parents of people with MS to determine whether there was a possible genetic link. They found that there was no overall increased or decreased risk of cancer among either mothers or fathers of those with MS, compared to parents of people without MS.
