7 Potential Lesions on the Roof of the Mouth Causes

  1. 1.Cold Sore

    Cold sores (also called oral herpes or fever blisters), are viral infections of the mouth caused by the herpes virus type 1. You were probably infected very early in life as a child when an adult kissed you. The virus stays asleep (dormant) and causes infections every now and then after exposure to lots of sun or emotional/physical stress. It is contagious when an outbreak is happening, but treatment is limited unless you are immunocompromised.

    1-2 weeks. Natural healing process starts within 24 hours of the initial sore starting.

Most of these cancers are squamous cell carcinomas (SCCs), meaning they begin in the flat (squamous) cells that make up the thin surface layer of the structures in the head and neck.

    Head and neck cancers span different types of cancer with variable prognosis so a consultation with an oncologist is required to determine outlook.
