What does a large hard lump on the right side of neck mean?

There are many potential causes for a large hard lump on the right side of the neck. Some of the more common causes include:

- Swollen lymph nodes: Lymph nodes are small, bean-shaped structures located throughout the body that help fight infection. When they become swollen, it can be a sign of an infection or other medical condition.

- Thyroid nodules: Thyroid nodules are growths that can occur on the thyroid gland, which is located in the front of the neck. Most thyroid nodules are benign (non-cancerous), but some can be cancerous.

- Warts: Warts are small, fleshy growths that can occur anywhere on the body, including the neck. They are caused by a virus and are usually harmless, but they can be unsightly or uncomfortable.

- Cysts: Cysts are fluid-filled sacs that can occur anywhere on the body. They are usually benign, but they can sometimes become infected or painful.

- Skin cancer: Skin cancer can occur anywhere on the body, including the neck. The most common type of skin cancer on the neck is squamous cell carcinoma.

If you are concerned about a large hard lump on the right side of your neck, it is important to see a doctor for evaluation. The doctor will be able to determine the cause of the lump and recommend the best course of treatment.
