Palpable lymph nodes are those that can be felt by touch due to swelling or enlargement, typically located in areas such as the neck, underarms, or groin. Lymph nodes are small, bean-shaped structures part of the lymphatic system, which plays a crucial role in immune response by filtering lymph fluid and trapping pathogens. When lymph nodes become enlarged, they are often palpable and can indicate an underlying issue. Causes of palpable lymph nodes include infections, such as colds, flu, or bacterial infections like strep throat, which can cause the nodes to swell as they work to combat the infection. Other causes include inflammatory conditions, such as rheumatoid arthritis or lupus, which can lead to lymph node enlargement. Additionally, cancers such as lymphoma or leukemia can cause lymph nodes to become swollen and hard. In some cases, metastatic cancer, where cancer spreads from another part of the body, can also result in swollen lymph nodes. Treatment for palpable lymph nodes depends on the underlying cause. For infections, treatment typically involves antibiotics or antiviral medications, along with supportive care such as rest and hydration. Inflammatory conditions may be managed with anti-inflammatory medications or disease-modifying treatments. For cancer, treatment could include chemotherapy, radiation therapy, or surgery, depending on the type and stage of cancer. A healthcare professional should evaluate any new or persistent lymph node swelling to determine the appropriate diagnostic tests and treatment plan. Early diagnosis and intervention are important for addressing the underlying cause and managing symptoms effectively.
