Diagnosing And Treating Lumps On Jaw Bone?

Treating a lump on jaw bone can be a long and drawn out process that can take months to fully diagnose and treat. There are various tests and scans that your doctor may order to determine what exactly the lump is. This may include an MRI or even a CAT scan. Your physician will then make a diagnosis of the lump after reviewing the results from the scan.

If your lump on jaw bone is a tumor, it can be further diagnosed into different categories. These categories include:


Pre-cancerous (abnormal cells that have not spread)

Malignant (cancerous cells that have spread)

If the lump is malignant, your physician will then determine what type of cancer you have based on its appearance and how far the cancer has spread to other parts of the body. Your physician may also take a small tissue sample to examine it under a microscope.

Once the lump on jaw bone has been diagnosed, your physician will determine the best course of treatment to eliminate the cancerous cells. This may include radiation therapy, chemotherapy, or surgery to completely remove the tumor or to cut out the affected area. Treating lump on jaw bone can be time-consuming and painful. During and after treatment you may experience side effects such as hair loss, nausea, fatigue and even pain.

It is important that you closely follow your physician’s orders while undergoing any type of treatment. This will help eliminate the chances of the cancer returning or spreading to other parts of the body. Speak to your physician if you have any questions or concerns about lump on jaw bone or any type of treatment that has been recommended to you.
