A Thyroid Cancer Surgeon in Bangalore can help patients understand that thyroid cancer is not a single disease. There are different types of thyroid cancer, and each type can behave differently, grow at different rates, and require a different treatment approach. Understanding these differences can help patients have more informed conversations with their healthcare team.
In this Video, Dr. Satish C, Surgical Oncologist, explains the four main types of thyroid cancer, how they differ, and why identifying the specific type is important when planning treatment.
Thyroid cancer develops when abnormal cells in the thyroid gland begin to grow uncontrollably. The thyroid is a small, butterfly-shaped gland located at the front of the neck and plays an important role in regulating metabolism and other body functions.
Thyroid cancers are classified based on the type of thyroid cell from which the cancer develops. The four main types are papillary, follicular, medullary, and anaplastic thyroid cancer.
1. Papillary Thyroid Cancer
Papillary thyroid cancer is the most common type of thyroid cancer. It generally grows slowly and often has a good prognosis, particularly when diagnosed at an early stage.
It can occur at different ages and may sometimes spread to nearby lymph nodes in the neck. Despite this, many patients can be successfully treated.
Treatment may involve surgery, and depending on the individual case, additional treatments such as radioactive iodine may be considered.
2. Follicular Thyroid Cancer
Follicular thyroid cancer is the second most common differentiated thyroid cancer. It develops from follicular cells of the thyroid.
Unlike papillary thyroid cancer, follicular thyroid cancer is more likely to spread through the bloodstream to areas such as the bones or lungs. However, its behaviour varies between individuals.
Surgery is often an important part of treatment, with additional treatment considered depending on the tumour’s characteristics and stage.
3. Medullary Thyroid Cancer
Medullary thyroid cancer develops from C cells, which produce the hormone calcitonin. It accounts for a smaller proportion of thyroid cancers compared with papillary and follicular types.
Some cases occur sporadically, while others are associated with inherited genetic conditions, particularly changes involving the RET gene.
Because inherited forms can run in families, genetic evaluation may be recommended in appropriate cases. Treatment planning may differ from that used for differentiated thyroid cancers.
4. Anaplastic Thyroid Cancer
Anaplastic thyroid cancer is a rare but aggressive form of thyroid cancer. It can grow quickly and may cause symptoms such as rapidly increasing neck swelling, difficulty swallowing, breathing problems, or changes in the voice.
Because it can progress rapidly, prompt evaluation and treatment planning are important. Management may involve a combination of surgery, radiation therapy, systemic treatment, or targeted therapies depending on the individual case.
Knowing the exact type of thyroid cancer helps doctors understand its expected behaviour and select appropriate treatment. Factors such as tumour size, spread, stage, molecular characteristics, and the patient’s overall health may also influence treatment decisions.
A thyroid nodule does not automatically mean cancer. When a suspicious thyroid nodule is identified, appropriate evaluation may include ultrasound, blood tests, and, when indicated, a fine-needle aspiration biopsy.
Conclusion
The four main types of thyroid cancer—papillary, follicular, medullary, and anaplastic—have different biological characteristics and may require different treatment approaches. Understanding the specific type is an important step in planning appropriate care.
If you have been diagnosed with thyroid cancer or have concerns about a suspicious thyroid nodule, consulting a Thyroid Cancer Surgeon in Bangalore can help you understand the diagnosis and available treatment options. A Best Surgical Oncologist in Bangalore can also guide you through evaluation, surgical planning, and multidisciplinary cancer care.
FAQ's
The four main types are papillary, follicular, medullary, and anaplastic thyroid cancer.
Papillary thyroid cancer is the most common type.
No. Treatment depends on the type, stage, tumour characteristics, spread, and individual patient factors.
Some cases of medullary thyroid cancer are associated with inherited genetic conditions. Genetic counselling and testing may be recommended when appropriate.
No. Most thyroid nodules are not cancerous. However, suspicious nodules may require further evaluation.
