What is a symptom commonly associated with Hodgkin's lymphoma?

In Hodgkin's lymphoma, one of the hallmark symptoms is the presence of enlarged lymph nodes that are typically mobile and nontender. This characteristic helps differentiate Hodgkin's lymphoma from other conditions that may cause lymphadenopathy. The hallmark of these lymph nodes is that they are painless rather than painful, which is a key feature when diagnosing this type of lymphoma.

While enlarged lymph nodes are present, they usually do not exhibit tenderness, which distinguishes Hodgkin's lymphoma from other conditions such as infections, where lymph nodes are often tender due to associated inflammation or infection. The mobility of the lymph nodes in Hodgkin's lymphoma also suggests a degree of differentiation from metastatic disease, where lymph nodes may be fixed or hard to the touch.

The other options represent symptoms that do not accurately correspond to Hodgkin's lymphoma. For instance, painful nodules are generally not characteristic of this condition, and a chronic cough can result from various causes, including other malignancies or infections, but is not a specific symptom linked to Hodgkin's lymphoma itself. Therefore, the correct answer reflects the typical presentation associated with the disease, emphasizing the nature of the lymph nodes involved.
