When Persistent Swollen Lymph Nodes May Need Lymphoma Evaluation
Swollen lymph nodes can happen during ordinary infections.
They can also be linked to lymphoma, which is a type of cancer.
Because the symptoms can look similar, one symptom alone does not provide an answer.
Doctors recommend watching how long symptoms last and whether they change.
A fever without a clear explanation may need medical attention.
A lump that stays swollen or gets bigger should also be checked.
Unexplained weight loss and night sweats are other signs to notice.
Several of these symptoms happening together may require further assessment.
Lymphoma symptoms can resemble those of a routine infection.
Doctors say symptom patterns and persistence matter more than one symptom.
An unexplained fever may warrant further medical assessment.
A lump that stays swollen or grows should be evaluated.
Unexplained weight loss and night sweats are additional warning signs, especially together.
