Can you give blood if you have thyroid cancer?

Can you give blood if you have thyroid cancer?

Probably not: This is a really good question. I would check with yout local blood bank but as far as I know, the only 2 cancers that will allow you to donate blood are: basal cell carcinoma of the skin and carcinoma in-situ of the cervix. Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

If you have thyroid cancer will your TSH level in your blood test be bad?

If you have thyroid cancer will your TSH level in your blood test be bad?

No: Your blood tests can all be completely normal with thyroid cancer. There is absolutely no correlation between your blood tests and thyroid cancer. The only way to diagnose thyroid cancer is by fna of a suspicious nodule. Read more

If you have thyroid cancer will your TSH level in your blood test abnormal?

If you have thyroid cancer will your TSH level in your blood test abnormal?

No: A physician cannot tell that you have thyroid cancer by looking at the TSH level. The best way to evaluate for malignancy in a thyroid is to perform a fine needle biopsy. Read more

If you have thyroid cancer will your TSH level in your blood test be abnormal?

If you have thyroid cancer will your TSH level in your blood test be abnormal?

Not usually: Most people with thyroid cancer have thyroid glands that work normally, and have a normal TSH - at least until they are removed! It is possible to have thyroid cancer and have an abnormal tsh, but this is uncommon. Read more

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

Not necessarily: Tsh stands for thyroid stimulating hormone. It does exactly that-- tells your thyroid to make thyroid hormone. If your thyroid isn't making enough hormone, your TSH will increase. And if your thyroid is making too much hormone, your TSH will go down. But cancer is usually not the cause for a high or low tsh. And you can have a completely normal TSH and still have thyroid cancer. Hope that helps! 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

Could you tell me if someone has thyroid cancer wouldn't the CBC blood test show that something was abnormal?

Could you tell me if someone has thyroid cancer wouldn't the CBC blood test show that something was abnormal?

Cancer: Likely not. The cancer if it spread would likely just affect local structures. Ultrasound is the best method to detect it. Certain lab tests screen for certain types of thyroid cancer. Read more

Are thyrogen injections and blood work as effective as I123 and scan in determining thyroid cancer reccurence?

Are thyrogen injections and blood work as effective as I123 and scan in determining thyroid cancer reccurence?

Thyroid cancer: A thyroidologist or endocrinologist are best qualified to follow a patient who has been treated for thyroid cancer. Scanning of the thyroid area is one way of detecting recurrence, but other more specialized methods may be used by specialists in this field. Read more

I have a couple of 6mm lymp nodes and my mchc came back low on my blood test. Does one have to do with the other? I also had thyroid cancer last year.

I have a couple of 6mm lymp nodes and my mchc came back low on my blood test. Does one have to do with the other? I also had thyroid cancer last year.

Cannot say: Cannot say in your particular case, but generally, 6mm lymph nodes are not necessarily significant. MCHC low implies low iron, but can be wtih a chronic disease (active or recovering from cancer, among many many others).
BUt could also theoretically be the beginning of a return of the cancer. Read more

Does thyroid cancer cause blood in stool?

Does thyroid cancer cause blood in stool?

No: This is not something routinely seen with thyroid cancer. It's somewhat possible that this could happen if the cancer had spread to involve the GI tract but this isn't a common occurance either. Read more

Ultrasound shows 7 nodules; blood work is normal. History of thyroid cancer in family. Dr. Says wait a year and recheck. Good advice? Get 2nd opinion?

Ultrasound shows 7 nodules; blood work is normal. History of thyroid cancer in family. Dr. Says wait a year and recheck. Good advice? Get 2nd opinion?

Sounds Ok: Annual re-examination is usually fine, and if any of the nodules reveal 15-20% growth, sampling with a needle (biopsy) can be considered at that time. Read more

Been told I have a full thyroid. Blood work fine. Would an MRI with contrast detect thyroid cancer? Had a recent one for an MS checkup.

Been told I have a full thyroid. Blood work fine. Would an MRI with contrast detect thyroid cancer? Had a recent one for an MS checkup.

No MRI: You don't need an MRI of the thyroid. I am not sure you need anything. What is a "full thyroid"? You have to ask your doctor what is meant by that. It may mean it is slightly enlarged. Most of the causes of that are benign. You may want to see an endocrinologist.... Rather than get an unnecessary test. Also, be careful not to overreact to things your doctor may say/write.

My blood test showed an elevated level of tg antibodies. Does that mean I have cancerous cells running around? Had papillary thyroid cancer a year ago

My blood test showed an elevated level of tg antibodies. Does that mean I have cancerous cells running around? Had papillary thyroid cancer a year ago

Not necessarily.: Having elevated tg antibodies primarily means that the more important tg test itself will be falsely lower than its true value. (no conversion formula exists.)

if your tg antibodies are only 20 or so, with an undetectable tg level, it is hard to know what that means. If your tg antibodies are much higher, then concern for the presence of thyroid cancer would increase. Read more

I had my thyroid removed in 1991 due to thyroid cancer, have been on Synthroid until approx 9 months ago. . I was really sick before Christmas this year and thought it was the flu. . . dr. Did a thyroid blood test and ths level is 477. . . he said t

Must take thyroid: I don't know what your question is, but it appears that you were not taking Synthroid (thyroxine) for many months. This is very dangerous. Your body requires thyroid hormone to function correctly. Since you had your thyroid removed, there is no alternative to taking thyroid hormone. Having had thyroid cancer, it is essential that the TSH be normal. Read more

How fast does papillary thyroid cancer spread. Can I give myself 3 months for complete checks. Fna and molecular marker tests by www. Veracyte. Com?

How fast does papillary thyroid cancer spread. Can I give myself 3 months for complete checks. Fna and molecular marker tests by www. Veracyte. Com?

Not fast: By far most common thyroid cancer. Highly curable, with very good likelihood that you will live normal lfe span. Must be treated by medical oncologist and/or endocrinologist; am not either one, so can't supply details about the testing you are talking about. Let your physician guide the frequency of follow up.

How can you tell if you have thyroid cancer in the cervix thank you?

Please clarify: It would be extraordinarily unusual for thyroid cancer to spread to the cervix. It is fairly common however for thyroid cancer to go the the cervical lymph nodes. This means the lymph nodes in the neck around the thyroid. These can be checked by the scans done before surgery and possibly with removal of the nodes during the thyroid operation. Read more
