How do you know if the lymp nude is cancerous?

To determine if a lymph node is cancerous, a healthcare provider typically performs imaging tests like ultrasound, CT scans, or MRIs to assess its size and characteristics. A definitive diagnosis often requires a biopsy, where a sample of the lymph node tissue is examined under a microscope for cancer cells. Symptoms such as unexplained swelling, pain, or changes in surrounding tissues can also indicate potential malignancy. Consulting a medical professional for appropriate evaluation is crucial.
