2. Follicular Thyroid Cancer (FTC): Beyond the Basics
Next in line is Follicular Thyroid Cancer, often encapsulated by the abbreviation FTC. Making up approximately 10 to 15% of thyroid cancer cases, FTC is the second most common type.
FTC’s defining characteristic is its tendency to spread via the bloodstream, as opposed to local expansion observed in PTC. This hematogenous spread means that FTC can reach distant organs such as the lungs and bones, introducing additional challenges in disease management.
FTC shows a peculiar geographical distribution, with higher prevalence observed in regions where dietary iodine intake is insufficient. This connection between dietary iodine and FTC provides critical insight into possible preventative measures.
The disease also shows a predilection for older individuals, specifically those over 50 years old. Despite the risk of distant metastasis, the overall prognosis for FTC is generally positive, particularly when early detection and intervention are possible.
The causes of FTC largely remain a mystery. Though a definitive trigger is yet to be identified, certain risk factors are commonly implicated. These include a lack of iodine in the diet, exposure to low levels of radiation, and specific inherited genetic conditions.
Symptoms of FTC mirror those of PTC, making differentiation based on symptoms alone challenging. These can include a lump or nodule in the neck, difficulty swallowing, changes in voice, and, in rare instances, neck pain. Owing to the similarity of symptoms with other conditions, seeking professional medical advice is crucial to reach an accurate diagnosis and commence appropriate treatment. (2)
