Causes and risk factors for thyroid cancer

Causes and risk factors for thyroid cancer

Like any other cancer, causes thyroid cancer is unknown, but the cancer is generally 

caused 

by a series of mutations that are inherited or occur during the life of the genetic material of 

people.
Nevertheless know some risk factors that increase the possibility of follicular cancer, 

namely:

    Exposure to radioactive materials in abundance, either from the environment or those 

used for medical purposes for the diagnosis or treatment. Risk is directly proportional to the 

amount of radiation and with how much was her early exposure. It is worth mentioning that 

the radiation used in the diagnosis of dental disease is large and does not constitute a risk 

factor at all.

Generation: Most cases occur between generation 25 and 65.
  
Sex: Women more likely.
 
 Iodine deficiency: Today is not a problem in the Western world.
 
 Family history of thyroid disease in general and cancer in particular.

What is thyroid cancer

What is thyroid cancer?


Is a division of thyroid cells independently and without supervision. There are two basic types according to the source of the cancer cells. The thyroid cancer is relatively uncommon, and is usually detected early, so full curable in most cases.
 
Types of thyroid cancer

There are two types of cells in the thyroid gland by embryonic origin and function:


1- (Follicular)

 Follicular carcinoma or  Papillary carcinoma    This type of cancer is more common.

2- ( Endodontic )

 Endodontic carcinoma   This type of cancer is very rare.
