What Does Rubbery Thyroid Nodule Indicate
I have several heterogeneous thyroid nodules and cysts with 7mm biggest in size. What does this indicate?
Common. Don't worry: Many people have nodules as they get older. Don't worry about them if they are less than 1cm in size. When and if they get bigger, then we biopsy the solid ones and aspirate the fluid with a needle. ...Read more
Fnac report of thyroid nodule-colloid, individual follicular cell n folliculr cell in cluster in haemorrhagic bckground. What it indicate?
Does a partially calcified thyroid nodule measuring 1cm indicate higher risk for ca? I had stage 2 ov ca at age 26 (3yrs ago) does that raise risk too?
Male with dominant homogenous solid thyroid nodule in midpoint that measures 1.1x1.3x1.7. Does this indicate a high cancer risk? Are most benign?
Most are benign: Hi. Yes, most nodules with those characteristics are benign. I'll assume you're not hyperthyroid (hyper-functioning nodules are NEVER cancer). Nevertheless, the chance of cancer is high enough (about 10-15% for nodules like that) that you MUST get it biopsied (non-surgical needle biopsy with gene testing is recommended). Don't ignore it, and don't ASSUME benignity. Cheers! ...Read more
Variable: Thyroid nodules are variable in their growth patterns. Some can grow quickly in size, particularly if there is a cystic component to the nodule. Your doctor will usually suggest an ultrasound to follow the growth of the nodule every 6 months to one year, depending on the level of suspicion. ...Read more
Usually not: In the distant past, thyroid hormone was used to 'shrink' nodules. More recent studies with ultrasound monitoring has shown that most nodules do not shrink with thyroid hormone treatment. Because thyroid cancer is the fastest increasing cancer in women, it is important to follow most thyroid nodules with ultrasound. With hashimoto's thyroiditis, there can be false or pseudonodules. ...Read more
May need biopsy: The management of thyroid nodules depends on a number of factors. How big are they? What do they look like on ultrasound? Are they "hot" (take up radioiodine) or cold? Are they part of a multinodular goiter or hashimotos thyroiditis? The risk of a nodule being cancer is usually low, but big, solitary nodules are more worrisome. A biopsy is an easy procedure by someone trained in this. ...Read more
Several steps: 1) history and physical exam by doctor, 2) blood test to assess thyroid function. If hyperthyroid: needs treatment and usually a nuclear scan. 3) if thyroid function is normal or depressed usually a thyroid ultrasound is done 4) if nodule is solid or suspicious then fine needle aspiration. 5) if benign: follow-up - if malignant (or suggestive) refer to qualified surgeon. ...Read more
Very common problem: Thyroid nodules are very common. We do not know why they appear. They normally do not cause functional changes in the thyroid. Once they are found, thyroid labs are done and ultrasound is used to evaluate. Those over 1 cm often get biopsied with fine needle aspiration biopsy. Luckily, about 95% of nodules are benign. ...Read more
Depends on problem: 3 major categories of potential health issues caused by thyroid nodules: a) large size affecting swallowing, breathing, voice ; b) over active production of thyroid hormone (hyperthyroid) ; and c) ~5% of nodules are cancer. Methimazole and ptu (propylthiouracil) are pills that block thyroid hormone production, treating b) above. Radioactive i-131 can shrink/destroy nodule, treating a) and b). Need surgery for c). ...Read more
Complicated question: Most nodules are initially treated with a biopsy. Additional therapy, if any, will depend on the results of that biopsy and any other symptoms or signs associated with that nodule. In truth, the treatment for any thyroid nodule is very individualized and impossible to generalize further. ...Read more
Only occassionally: While almost all thyroid cancers are cold, so are most benign nodules. If the nodule is hot, it is extremely rare for it to be cancer. If it is cold and looks suspicious on an ultrasound performed or at least interpreted by a very experienced clinician, it should be biopsied to see if surgery is necessary. ...Read more
Depends on the cause: If a nodule is due to hashimoto's thyroiditis (inflammation caused by autoimmunity, where one's own immune system attacks one's proteins and tissues), then taking thyroid hormone pills can shrink it. If it's a tumor that's over-producing thyroid hormone, radioactive iodine can kill it, and make it smaller). Fluid-filled cysts can be drained with a needle, but may grow back. Cancer needs surgery. ...Read more
Variables: Radioactive Iodine treatment for hyperthyroidism tends to have a much higher success rate than medications. Depending on the dose of radioactive iodine chosen, and the disease under treatment (Grave's vs toxic goitre, vs hot nodule etc), success rate in achieving definitive resolution of the hyperthyroidism may vary from 75-100%. A major expected side effect of radioactive iodine in hypothyroidism ...Read more
It could be a colloid cyst - an accumulation of thyroid hormone. It could be a benign adenoma - an area of thyroid gland that is growing slightly differently/faster than the rest of the gland.
Most physicians follow benign thyroid nodules to see if they are growing or changing, which may necessitate another biopsy. ...Read more
