Evaluation warranted: Depending on how low the white count, it would be wise to continue to be followed by a primary health care provider and/or hematologist. It will likely return to normal, but it should be followed. ...Read more

Post op thyroid: Surgery for cancer the replacement thyroxine should be dosed sufficient to keep TSH low to avoid stimulating any tumor remnants. Most Endocrinologists advise suppressing tsh for about 5 years. Thyroglobulin levels and antibodies should also be measured. Your TSH level appears adequately suppressed.

I recently had a thyroid blood test done. It was normal. If I have cancer in my body would it show up with the blood test?

I recently had a thyroid blood test done. It was normal. If I have cancer in my body would it show up with the blood test?

No: A blood test for thyroid function will not reveal cancer, not even thyroid cancer. There are virtually no reliable blood tests for cancer, exceptions being cancers of blood. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Past thyroid cancer, now years later I have abnormal blood calcium, what to do?

Past thyroid cancer, now years later I have abnormal blood calcium, what to do?

Parathyroids: Presumably, your thyroid cancer treatment involved surgery and radioactive iodine. Usually, this preserves the parathyoid glands, but sometimes they can get damaged. Parathyroids make PTH which maintains blood Ca. If PTH is low, your blood Ca will fall, and cause a number of symptoms. For starters, get an ionized Ca and PTH. See your Endocrinologist. ...Read more

I had thyroid cancer in the past. Now years later I have abnormal blood calcium. Could these be related?

I had thyroid cancer in the past. Now years later I have abnormal blood calcium. Could these be related?

Some relationship: Calcium metabolism is controlled vial the parathyroid glands. There are 4 such glands, 2 on top of the thyroid and 2 at the lower pole. When a total thyroidectomy is performed for Ca some of the glands may be injured and the Ca++ levels drop. If the remaining glands grow post op they produce excess hormone then the level of serum Ca++ becomes elevated. ...Read more

FineNeedle aspiratio: 4-7 % thyroid nodules can be cancerous. What was your TSH levels. Was a fine needle aspiration (FNA) ever performed on this nodule? If TSH IS NORMAL get FNA! If TSH lower than normal get Nuclear Thyroid Scan. If scan shows non functioning nodule...then get FNA. If FUNCTIONING NODULE check FT4 and T3 (liothyronine) levels. Certain characteristics of a nodule that can be worrisome talk to an Endocrinologist. ...Read more
