Can benign thyroid nodule become malignant?

Well... A thyroid nodule is technically not "benign" unless it's surgically removed and the pathologist found no cancer in the specimen. A nodule that is still in your neck could still be cancerous despite a "benign" biopsy because not all of the nodule is cancerous. Sometime it's just a speck that is cancerous and was missed during the biopsy. That's why it's important to continue to follow the nodule.
Yes. Rarely. But possible. Need to have them evaluated and removed, if there is a suspicion. By putting a thin needle in the nodule and taking fluid for examination (fna) usually helps in making the decision whether it needs to be surgically removed or just followed.

Could it happen such that a benign thyroid nodule turn into malignant years later?

Not likely. Benign thyroid nodules almost always remain that way. The more likely instance is that a malignant nodule grew within the benign nodule (more likely when the benign nodule is large). These are usually examined on ultrasound and biopsies via fine needle aspiration or core biopsy. Read more about it here: http://www.Conciergeradiologist.Com/ultrasound-guided-biopsy.Html.

High chance . The presence of microcalcifications is highly specific for malignancy and has important diagnostic value. If the nodule is indeed malignant and the only site of disease the cure rate and survival rate of thyroid cancer detected in early stage is very high. Read more...

Is a heterogeneously hypoechonic nodule 1.4x1.1x1.1cm thyroid nodule with microlobulated margins with no calcifications is a possible malignant one?

No definite answer. There's no way to know from an ultrasound whether a thyroid nodule is malignant or benign. Don't be fooled by Radiologist - all imaging is limited in its ability to diagnose these conditions. The only way to tell for certain about malignancy is to undergo a biopsy. In the mean time, an iodine uptake-and-scan could help. You'll need blood tests & the help of an endocrinologist as well. Use HT Prime. Read more...
