Genetics and family history
Last but not least, there are genetic thyroid cancer causes. One type of thyroid cancer known as medullary thyroid carcinoma (MTC). Based on data, about 2 out of every 5 MTC cases are caused by an abnormal gene.
This abnormal MTC gene can be inherited, or passed on in generations. If one of your parents, grandparents, or siblings has been diagnosed with MTC, there is a chance that you also carry the gene. However, it does not guarantee that you will develop cancer.
This type of thyroid cancer is less common, however, it can develop in childhood or early adulthood instead of later on in life. MTC tends to be more aggressive and have a lower survival rate than other thyroid cancers, such as papillary thyroid carcinoma.
In summary, there are several thyroid cancer causes, two of which are being female and exposure to radiation. In addition, thyroid cancer is treatable with surgery and has a high survivability rate.
Talk to your doctor, endocrinologist, or oncologist if you feel like your thyroid is causing some problems for you.
