Actually, whether it is Hodgkin's lymphoma or non-Hodgkin's lymphoma, the symptoms and signs are quite similar. In terms of symptoms, because lymphoma mainly occurs as a lesion in the lymph nodes, it is characterized by superficial, localized enlargement of the lymph nodes. Common locations include the neck, then the armpits, and the groin—areas where lymph nodes are more prevalent. It manifests as a local swelling; simply put, you might feel a lump or a tumor on your neck, which is the most common symptom. Additionally, there are other systemic symptoms including fever, weight loss, night sweats, and itchy skin, among others. As for the physical signs, it mainly refers to palpable superficial lymph node enlargement upon examination.
