Condition Lookup

Non-Small Cell Lung Cancer (NSCLC)

Specialty: Oncology

Sub-category: Lung Cancer

Symptoms:
persistent cough; chest pain; shortness of breath; wheezing; unexplained weight loss; fatigue; hemoptysis (coughing up blood)

Root Cause:
Abnormal and uncontrolled growth of lung cells leading to tumor formation in the lung.

How it's Diagnosed: videos
Diagnosis typically involves imaging tests (CT scan, chest X-ray), biopsy (either via bronchoscopy, needle biopsy, or surgery), and molecular testing for genetic mutations.

Treatment:
Treatment options depend on the stage and type but can include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy.

Medications:
Chemotherapy drugs such as cisplatin (alkylating agent) and pemetrexed (antimetabolite); targeted therapies like osimertinib (EGFR inhibitor); immunotherapies such as nivolumab (checkpoint inhibitor).

Prevalence: How common the health condition is within a specific population.
NSCLC accounts for approximately 85% of all lung cancer cases.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Smoking (primary risk factor), exposure to secondhand smoke, environmental toxins (e.g., radon, asbestos), family history, older age.

Prognosis: The expected outcome or course of the condition over time.
Prognosis depends on the stage at diagnosis. Early-stage NSCLC has a better prognosis, with survival rates improving with surgery or targeted therapy; advanced stages generally have lower survival rates.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Respiratory failure, metastasis to other organs, pleural effusion, recurrence after treatment, and side effects from treatments (e.g., chemotherapy-induced neutropenia).

Small Cell Lung Cancer (SCLC)

Specialty: Oncology

Category: Thoracic Cancers

Sub-category: Lung Cancer

Symptoms:
cough; chest pain; shortness of breath; wheezing; hoarseness; unexplained weight loss; fatigue; paraneoplastic syndromes (e.g., siadh, cushing’s syndrome)

Root Cause:
Rapidly growing, aggressive cancer that typically starts in the bronchi and spreads early to other parts of the body.

How it's Diagnosed: videos
Diagnosis often involves chest imaging (X-ray, CT), biopsy (bronchoscopy or needle biopsy), and staging with PET scan to assess metastasis.

Treatment:
Treatment primarily involves chemotherapy and radiation. SCLC is less commonly treated with surgery due to its early spread.

Medications:
Chemotherapy regimens typically include etoposide (topoisomerase inhibitor) and cisplatin (alkylating agent). Immunotherapy agents like atezolizumab are also used in combination with chemotherapy.

Prevalence: How common the health condition is within a specific population.
SCLC accounts for about 15% of all lung cancer cases.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Smoking (strongest risk factor), secondhand smoke exposure, occupational exposures (asbestos, radon), genetic predisposition.

Prognosis: The expected outcome or course of the condition over time.
SCLC is aggressive with a poor prognosis. It often metastasizes quickly and is typically diagnosed at a later stage. However, with early diagnosis and aggressive treatment, some patients may achieve remission.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Metastasis to brain, liver, and bones, paraneoplastic syndromes, treatment-related side effects, and cachexia.

Lung Carcinoid Tumors

Specialty: Oncology

Category: Thoracic Cancers

Sub-category: Lung Cancer

Symptoms:
persistent cough; wheezing; chest pain; shortness of breath; unexplained weight loss; fatigue; coughing up blood (hemoptysis); recurrent pneumonia

Root Cause:
Slow-growing neuroendocrine tumors that form in the lung tissue, often originating from bronchial epithelial cells.

How it's Diagnosed: videos
Diagnosis typically involves imaging (CT scans, X-ray), biopsy (bronchoscopy or percutaneous biopsy), and possibly a bronchial lavage or cytology. Immunohistochemistry is used to confirm the neuroendocrine nature of the tumor.

Treatment:
Surgery is the primary treatment for localized carcinoid tumors. For advanced stages, treatments may include chemotherapy or somatostatin analogs (e.g., octreotide) for symptom control and slowing tumor growth.

Medications:
Somatostatin analogs (e.g., octreotide ) for symptom control, chemotherapy agents such as streptozocin (alkylating agent) or etoposide (topoisomerase inhibitor) for advanced disease.

Prevalence: How common the health condition is within a specific population.
Lung carcinoid tumors are rare, accounting for about 1–2% of all lung cancers.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Smoking is less of a risk factor compared to other types of lung cancer. There may be associations with genetic conditions such as multiple endocrine neoplasia (MEN) syndrome.

Prognosis: The expected outcome or course of the condition over time.
Generally good prognosis, especially when diagnosed early. These tumors tend to grow slowly and are often treatable with surgery, with many patients surviving long-term after removal of the tumor.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Metastasis (though rare), recurrence of tumors, carcinoid syndrome (flushing, diarrhea, wheezing), and treatment-related side effects.

Thymoma and Thymic Carcinoma

Specialty: Oncology

Category: Thoracic Cancers

Symptoms:
chest pain or discomfort; persistent cough; shortness of breath; fatigue; weight loss; myasthenia gravis (in some cases); difficulty swallowing

Root Cause:
Thymoma is a cancer originating from the thymus gland, located in the chest. Thymic carcinoma is a more aggressive form of thymic cancer.

How it's Diagnosed: videos
Chest X-ray. CT scan of the chest. MRI for better tissue detail. Biopsy (usually via CT-guided needle aspiration or mediastinoscopy). PET scan to check for metastasis.

Treatment:
Surgical resection (thymectomy) is the primary treatment, especially for thymoma. Radiation therapy if surgery is not fully effective or if cancer has spread. Chemotherapy for thymic carcinoma or advanced thymoma. Immunotherapy is sometimes considered in advanced stages.

Medications:
Chemotherapy drugs like cisplatin , doxorubicin , and cyclophosphamide are used for thymic carcinoma. For cases with myasthenia gravis, medications like corticosteroids or immunosuppressants (e.g., pyridostigmine ) may be prescribed. Targeted therapies and checkpoint inhibitors like pembrolizumab are being explored in clinical trials.

Prevalence: How common the health condition is within a specific population.
Thymomas are rare, with about 300-400 new cases annually in the U.S. Thymic carcinoma is even rarer.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Myasthenia gravis (autoimmune disorder). Other autoimmune diseases like lupus or rheumatoid arthritis. Family history of cancer. Genetic conditions like Li-Fraumeni syndrome or DiGeorge syndrome.

Prognosis: The expected outcome or course of the condition over time.
Prognosis for thymoma is relatively good when detected early and treated with surgery. The 5-year survival rate is about 70-90%. Thymic carcinoma has a poorer prognosis, especially if diagnosed at advanced stages.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Recurrence of cancer after treatment. Spread to surrounding organs (e.g., lungs, heart). Myasthenia gravis-related complications. Infection from treatments (e.g., surgery, chemotherapy).

Mesothelioma

Specialty: Oncology

Category: Thoracic Cancers

Symptoms:
shortness of breath; chest pain (pleuritic pain); persistent dry cough; fatigue; unexplained weight loss; night sweats; difficulty swallowing

Root Cause:
Mesothelioma is a rare but aggressive cancer that affects the mesothelial cells lining the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma), or heart (pericardial mesothelioma). It is most commonly caused by exposure to asbestos.

How it's Diagnosed: videos
Chest X-ray or abdominal X-ray. CT scan or MRI. Biopsy (thoracoscopic or peritoneoscopic). PET scan for staging. Blood tests (e.g., for markers like mesothelin, but these are not definitive).

Treatment:
Surgical resection (pleurectomy/decortication or extrapleural pneumonectomy). Radiation therapy, particularly for symptom control. Chemotherapy, often with drugs like cisplatin and pemetrexed. Immunotherapy using immune checkpoint inhibitors (e.g., nivolumab, ipilimumab). Palliative treatments to improve quality of life (e.g., pleurodesis for fluid buildup).

Medications:
Chemotherapy medications such as cisplatin and pemetrexed are commonly used to treat mesothelioma. Immunotherapy agents like nivolumab and pembrolizumab may be used for advanced stages of mesothelioma. Pain management drugs like opioids (e.g., morphine ) and nonsteroidal anti-inflammatory drugs (NSAIDs).

Prevalence: How common the health condition is within a specific population.
Mesothelioma is rare, with approximately 3,000 new cases per year in the U.S. The prevalence is expected to rise due to the long latency period after asbestos exposure (20-50 years).

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Exposure to asbestos, especially in occupational settings (e.g., construction, shipbuilding, mining). Family history of mesothelioma. Living with someone exposed to asbestos. Genetic mutations (in some cases).

Prognosis: The expected outcome or course of the condition over time.
Mesothelioma has a poor prognosis with a 5-year survival rate of less than 10%. Survival rates are higher in patients with localized disease treated with surgery.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Pleural effusion (fluid buildup in the lungs). Difficulty breathing (dyspnea). Spread to other organs (e.g., liver, peritoneum). Blood clotting disorders. Cachexia (severe weight loss and muscle wasting).
