Will thyroid cancer cause pain on the left side of the neck?

Whether a thyroid cancer patient will experience pain on the left side of the neck needs to be determined based on the type of thyroid cancer. Thyroid cancer is a common malignant tumor, including papillary carcinoma, follicular carcinoma, medullary carcinoma, and undifferentiated carcinoma.

1. Papillary carcinoma: Papillary carcinoma is a common type of thyroid cancer. There may be no obvious symptoms in the early stage. As the disease progresses, a lump in the neck may appear, accompanied by symptoms such as hoarseness and difficulty swallowing. If papillary carcinoma grows on the left thyroid gland, it may cause pain on the left side of the neck;

2. Follicular carcinoma: Follicular carcinoma is also a type of thyroid cancer. It usually starts insidiously and has no obvious symptoms in the early stage. When the disease progresses, symptoms such as lumps or nodules in the front of the neck and difficulty swallowing may appear. If follicular carcinoma grows in the left thyroid gland, it may cause pain on the left side of the neck;

3. Medullary carcinoma: Medullary carcinoma is a low-grade malignant thyroid cancer. The cause of the disease is related to genetic factors. After the disease, the patient will experience symptoms such as coughing, sputum, diarrhea, and facial flushing. If medullary carcinoma grows in the left thyroid gland, it may cause pain on the left side of the neck;

4. Undifferentiated cancer: Undifferentiated cancer is a highly malignant tumor. The cause of the disease is still unclear. It may be related to ionizing radiation or chemical stimulation. After the disease occurs, the patient will experience symptoms such as difficulty breathing, hoarseness, and difficulty swallowing. If undifferentiated cancer grows on the left thyroid gland, it may cause pain on the left side of the neck.

In addition to the above situations, if there is lymph node metastasis, it may also cause this phenomenon. It is recommended that patients go to the general surgery department of the hospital in time for treatment and complete blood routine examinations, ultrasound examinations and other definite diagnosis under the guidance of doctors.
