Differences Between Lung Cancer and Lymphoma

Two types of cancer may affect the lungs: primary lung cancer, which is cancer that begins in the lungs, and metastatic lung cancer, which is cancer from other locations in the body that spreads to the lungs. The two main types of lymphoma are cancers of the lymphatic system; these are Hodgkin's and non-Hodgkin's 5.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Onset of Disease

In lung cancer, symptoms are usually not present until the disease is advanced, according to the Mayo Clinic 1. Symptoms include coughing up blood, a new cough that lingers, shortness of breath and chest pain. Primary lung cancer is categorized as either small cell or non-small cell. Small cell lung cancer is typical for heavy smokers, and non-small cell lung cancer includes other cancer types such as squamous cell, large cell carcinoma and adenocarcinoma.

Symptoms for Hodgkin's and non-Hodgkin's lymphoma include fever, fatigue, itching, swollen lymph nodes and night sweats. Lymph nodes are found in clusters in the pelvis, neck, underarm and abdomen. MedlinePlus reports that in the majority of cases, the cause of non-Hodgkin's lymphoma is unknown 25.

No screening tests are used for lung cancer, reports the MD Anderson Cancer Center 3. Diagnostic testing options to determine the presence of lung cancer include: chest X-rays to spot abnormal areas in the lungs; computed tomography (CT) scans to create precise computerized pictures; bronchoscopy to look into the lungs and take a lung biopsy; fine-needle aspiration to obtain a tissue sample with a thin needle; sputum cytology to examine cells from expelled mucus; and thoracentesis to obtain fluid from the lungs for microscopic examination.

Lymphoma symptoms are similar to other disease processes and blood disorders and require a doctor's expertise for accurate diagnosis and treatment. Diagnostic procedures for Hodgkin's and non-Hodgkin's disease include blood tests and a lymph node biopsy for tissue examination under microscope.

Staging

Staging for non-small cell lung cancer includes: occult stage where cancer cells are found in sputum without the presence of a visible tumor in the lung; stage 0 with cancer cells in the lung's lining; stage 1A in which the tumor is less than 3 cm across.

Lymphoma staging is based on the extent of the spread of the tumor.
