Medullary Thyroid Cancer

Specialty: Oncology

Category: Solid Tumors

Sub-category: Endocrine Cancers

Symptoms:
lump in the neck; diarrhea; flushing; hoarseness; neck pain; enlarged lymph nodes

Root Cause:

Less common, accounting for 3–5% of thyroid cancers; more frequently diagnosed in people with hereditary genetic conditions like multiple endocrine neoplasia (MEN).

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Family history of medullary thyroid cancer, genetic mutations (RET mutations), and MEN syndrome types 2A and 2B.

Prognosis: The expected outcome or course of the condition over time.
Prognosis varies depending on stage; localized cases have good survival rates (80–90%), while advanced or metastatic cases have poorer outcomes.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Metastasis to the lymph nodes, lungs, liver, and bones; recurrence; and complications from treatment, such as hypocalcemia.

Anaplastic Thyroid Cancer

Specialty: Oncology

Category: Solid Tumors

Sub-category: Endocrine Cancers

Symptoms:
rapidly growing neck lump; difficulty breathing; difficulty swallowing; hoarseness; painful throat

Root Cause:
Highly aggressive cancer that arises from thyroid follicular cells; often associated with mutations in TP53, BRAF, or RAS genes.

How it's Diagnosed: videos
Fine-needle aspiration biopsy, imaging (CT, MRI, PET scans), and molecular testing for genetic mutations.

Treatment:
Surgery (if operable), external beam radiation, chemotherapy (doxorubicin, paclitaxel), and experimental targeted therapies.

Medications:
Doxorubicin (chemotherapy), paclitaxel (chemotherapy), and sorafenib (targeted therapy for advanced disease).

Prevalence: How common the health condition is within a specific population.
Rare, accounting for 1–2% of thyroid cancers. More common in older adults, usually after the age of 60.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Older age, prior history of thyroid cancer, genetic mutations (TP53), and environmental factors such as radiation exposure.

Prognosis: The expected outcome or course of the condition over time.
Very poor prognosis with a median survival of 6 months; the disease is often diagnosed at an advanced stage.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Rapid growth, metastasis to distant organs (lungs, bones), airway obstruction, and difficulty in treatment due to its aggressive nature.

Thyroid Cancer

Specialty: Oncology

Category: Solid Tumors

Sub-category: Endocrine Cancers

Symptoms:
lump or swelling in the neck; hoarseness; difficulty swallowing; persistent cough not due to a cold; neck pain; enlarged lymph nodes

Root Cause:
Abnormal growth of cells in the thyroid gland, which may be caused by genetic mutations, radiation exposure, or other factors.

How it's Diagnosed: videos
Physical exam, thyroid ultrasound, fine-needle aspiration biopsy, blood tests (TSH, thyroglobulin), imaging (CT, MRI), and radioactive iodine scans.

Treatment:
Treatment options include surgery (thyroidectomy), radioactive iodine therapy, external beam radiation, targeted therapy, and chemotherapy.

Medications:
Targeted therapy drugs such as sorafenib and lenvatinib (tyrosine kinase inhibitors) may be prescribed. Hormone replacement therapy with levothyroxine (thyroid hormone) is commonly required after thyroidectomy.

Prevalence: How common the health condition is within a specific population.
Approximately 1% of all cancers globally; more common in women and often diagnosed in individuals aged 30–60.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Family history of thyroid cancer, exposure to radiation, genetic mutations (e.g., RET proto-oncogene), iodine deficiency, and female sex.

Prognosis: The expected outcome or course of the condition over time.
Generally favorable, especially for differentiated thyroid cancers like papillary and follicular types; survival rates exceed 90% with early diagnosis and treatment.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Recurrent cancer, metastasis to other organs (lungs, bones), hypothyroidism after treatment, and damage to nearby structures (e.g., vocal cords, parathyroid glands).

Parathyroid Cancer

Specialty: Oncology

Category: Solid Tumors

Sub-category: Endocrine Cancers

Symptoms:
neck mass; hypercalcemia (elevated calcium levels); fatigue; weakness; kidney stones; bone pain

Root Cause:
Rare malignant tumor of the parathyroid gland, often resulting in overproduction of parathyroid hormone (PTH), leading to hypercalcemia.

How it's Diagnosed: videos
Elevated calcium and PTH levels in blood tests, neck ultrasound, fine-needle aspiration biopsy, and imaging (CT, MRI, PET scans).

Treatment:
Surgical excision of the parathyroid tumor, with lymph node dissection if needed. Chemotherapy and radiation may be used for advanced disease.

Medications:
Cinacalcet (calcium-sensing receptor agonist to lower calcium), bisphosphonates (to manage bone pain and prevent fractures), and pazopanib (targeted therapy for advanced disease).

Prevalence: How common the health condition is within a specific population.
Extremely rare, accounting for less than 1% of parathyroid disorders.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Previous radiation exposure, hyperparathyroidism, and familial hyperparathyroidism.

Prognosis: The expected outcome or course of the condition over time.
Prognosis depends on early detection and complete surgical resection; survival rates are lower in advanced cases due to frequent recurrence.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Recurrence of cancer, metastasis (especially to lungs and bones), hypercalcemia-related issues like kidney stones and osteoporosis.
