Noncancerous conditions may lead to a swollen salivary gland, including an infection or a stone in a salivary gland duct. Salivary gland cancer is a rare disease in which malignant cells form in the tissues of the salivary glands. Many types of cancer and benign (non-cancerous) tumors can develop in these glands.Treatment for salivary gland cancer is radiation therapy and chemotherapy. A lump or swelling on or near your jaw or in your neck or mouth, Numbness in part of your face.
The treatment options for salivary gland cancer depend largely on the stage (extent) of the cancer. Radiation therapy might be an option as the main treatment if surgery would result in serious problems with eating, speech, or appearance, or for people who refuse surgery. Radiation therapy may be advised after surgery if you have an intermediate- or high-grade cancer or an adenoid cystic carcinoma, if the cancer could not be removed completely, or if the edges of the removed area contain cancer cells.
Chemotherapy (chemo) may be added as well, but it’s not clear how helpful this is. Radiation therapy (with or without chemo) may be used as the main treatment if surgery is not a good option.
