An Informative post today


To raise awareness......
The following was written by Andi S Green on Helium.com

Thyroid cancers are quite rare. There are several types of thyroid cancer, papillary, medullar and anaplastic. If you find an abnormal lump in your throat or unusual swelling then it is still best to visit your Dr to have it checked out. You may have other symptoms such as temperature changes, appetite changes or energy level changes.

1) Thyroid cancer is linked to previous problem with the thyroid gland, even if benign.

2) Thyroid cancer is also linked to previous exposure to radiation. In the 1950's and 60's children were often treated with high dose x-rays to treat acne, enlarged tonsils or scalp infections. This deep x-ray treatment is a risk factor. Also people exposed to radioactive particles during atomic tests or nuclear accidents are also at risk.

3) Genetic causes/family history of thyroid cancer is again a risk factor. Medullary thyroid cancer can be caused by an alteration in a gene called RET. This has a strong inherited component. So if there is family history of medullary thyroid cancer then Drs may suggest removing your thyroid to avoid cancer occurring.

4) Certain other inherited conditions are linked with an increased risk from the disease. Gardner's Syndrome or Cowden disease are linked to a higher rate of incidence of thyroid cancer. Also a bowel condition called FAP is linked to the disease.

5) Females are 2.5 times more likely than males to acquire the disease.

6) Apparently white Americans are more likely than black Americans to acquire the disease.

7) Poor diet has been linked to the disease, especially a diet short in iodine.

8) Late pregnancy has been linked to greater susceptibility to the disease.

9) Age is a factor. Papillary and follicular cancers are more common in young adulthood where medullar is more common in adults.

Hopefully this gives a good overview of some of the general causes of thyroid cancer.

The following I found on About.com

When cancerous thyroid nodules are discovered during the first or second trimester, surgery should be offered in the second trimester. Well-differentiated thyroid cancers grow slowly, so if the evaluation indicates that the cancer is papillary or follicular, and there is no evidence of advanced disease, a woman may be offered the opportunity to wait until after childbirth for surgery.

A pregnant woman who has previously had thyroid cancer or a woman who has a confirmed thyroid cancer who is waiting until after delivery for thyroid surgery can receive treatment that will allow TSH to remain suppressed but detectable. Ideally, the free T4 or total T4 levels should remain within the normal range for pregnancy.

Radioactive iodine should not be given to women who are breastfeeding.

Women who receive therapeutic doses of radioactive iodine should wait six months to a year to become pregnant, to ensure that thyroid function is stable, and the thyroid cancer is in remission.
