The journal Cancer Prevention Research recently published a study that links estrogen and head and neck cancers in young women. The authors of the study say that estrogen triggers the activity of CYP1B1, an enzyme in the body. However, this was only detected in pre-cancerous cells; it did not occur in healthy cells or in those that had become cancerous. The authors of the study believe that CYP1B1 could be a good place to start when finding pre-cancerous lesions in the head and neck. Stopping it there could prevent cancer from spreading or moving to a more advanced stage. During the past 10 years, there has been an increase in the diagnosis of head and neck cancers among younger women, but most cases are still in men ages 50 to 74.
