Is there a bulge behind the ear a precursor to cancer?

Cancer usually does not exist before the occurrence of precursors, so, ear bulging is generally not a precursor to cancer, but in some cases, ear bulging may be a symptom of cancer.

There are many reasons behind the ear bulging, common are lymphadenitis, sebaceous cysts, cancer, etc. Lymph nodes are important immune organs in the human body, when inflammation occurs in surrounding organs or tissues, lymph nodes may swell, thus forming bulging behind the ear, usually disappear naturally after inflammation subsides. However, if the patient develops cancer such as thyroid cancer or basal cell carcinoma of the skin, it may cause swelling behind the ears.

If the swelling behind the ears continues to increase or causes discomfort, it is necessary to seek medical examination and treatment.
