Patient's question:
Swelling. 3 days.Doctor's answer:
Lymphadenopathy Lymphadenopathy is very common and can occur in people of any age. It can be seen in various diseases, including benign and malignant ones. Therefore, it is important to pay attention to the factors or causes of lymphadenopathy, seek medical attention promptly, and get a definitive diagnosis to avoid misdiagnosis or missed diagnosis. Below, we will discuss the common factors or causes of lymphadenopathy.Chronic lymphadenitis Most cases have obvious infection foci and are often localized lymphadenopathy with pain and tenderness. The diameter is generally no more than 2 to 3 cm, and it will shrink after anti-inflammatory treatment.
Groin lymphadenopathy, especially flat lymph nodes that persist without changes for a long time, often holds little significance. However, cervical or supraclavicular lymphadenopathy without obvious factors or causes indicates systemic lymphoid hyperplasia and should be taken seriously, requiring further examination to determine the cause.
Medical Advice Lymph nodes are distributed throughout the body, but they can only be palpated at relatively superficial special locations such as the submandibular region, neck, supraclavicular fossa, axilla, and groin. In women with breast cancer, swollen lymph nodes can be felt around the breast and in the axilla. The correct method of palpation is to press together the index and middle fingers and move them up and down and left and right in the aforementioned areas. If round, oval, or cord-like lymph nodes larger than the size of an egg are felt under the skin, it is important to seek medical diagnosis immediately.
Lymph nodes are part of the body's natural defense system, helping to resist infections and toxins. Superficial lymph node groups are present in the neck, axilla, groin, behind the knees, and in front of the ears. In children, the most common factors or causes of lymphadenopathy are infections. The location of the swelling depends on the site of the infection. Infections of the throat or ears may cause cervical lymphadenopathy, head infections may lead to lymphadenopathy behind the ears, hand or arm infections may cause axillary lymphadenopathy, and foot or leg infections may result in groin lymphadenopathy. The most common type of lymphadenopathy in children is cervical, which mothers can easily notice. It is important to take the child to a doctor for examination to feel relieved.
For most people, sore throat, colds, tooth inflammation (abscess), ear infections, or insect bites are common factors or causes of lymphadenopathy. However, if lymphadenopathy appears in the middle of the front of the neck or directly above the clavicle, you must consider factors or causes other than infection, such as tumors, cysts, or thyroid dysfunction. Most mothers, upon seeing swollen lymph nodes in their child's neck, first think of tumors, which is a natural reaction. Tumors are indeed a factor or cause of lymphadenopathy in children, but infections are more common. In such cases, blood and urine tests, X-ray examinations, skin tests, and biopsies can help confirm the doctor's diagnosis.
