Yes, nodules, including benign ones like thyroid nodules, can often enlarge or grow over time.
Even though many nodules are harmless, their size can change. Here's a more detailed breakdown:
-
Benign Nodules Can Grow: Just because a nodule is diagnosed as benign (non-cancerous) through methods like needle biopsy, it doesn't mean it will stay the same size. In fact, many benign nodules will gradually increase in size.
-
Why Size Matters: While a benign nodule is not cancerous, its growth can still cause problems:
- Compression: A larger nodule can compress surrounding structures, such as the trachea (windpipe) or esophagus, leading to difficulty breathing or swallowing.
- Cosmetic Concerns: A noticeable nodule in the neck region can be a cosmetic concern for some individuals.
- Hormone Production: In the case of thyroid nodules, some can become "autonomous," meaning they produce thyroid hormone independently of the body's needs, leading to hyperthyroidism.
-
Monitoring Nodules: Due to the potential for growth, nodules, even those initially diagnosed as benign, often require regular monitoring. This may involve:
- Ultrasound Scans: These scans help track the size and characteristics of the nodule over time.
- Repeat Biopsies: If a nodule shows significant growth or changes in appearance, a repeat biopsy might be recommended to ensure it remains benign.
In summary, while most nodules are benign, they have the potential to enlarge, which can sometimes necessitate intervention. Therefore, regular monitoring is essential to manage any potential complications.
