Do We Know What Causes Thymus Cancer?
Not much is known about why thymus cancers develop in some people but not in others. Researchers have found some DNA changes that occur more often in thymus cancer cells than in normal cells. (DNA is the chemical in each of our cells that makes up our genes — the instructions for how our cells function.) However, they are still not certain why these changes occur in some people, exactly how the changes occur, and how the changes might cause cancer to form.
