My 18 year old sister was just diagnosed with squamous cell carcinoma on the base of the right side of her tongue 10/08/13. She's had this "sore" in her mouth that wouldn't heal for close to 5 months before having it seen about. All we have right now is the diagnosis. We don't know the stage. I was hoping to hear from someone who has survived this that can offer information. As you already know, a cancer diagnosis is so so scary and we could use a little encouragement. Thanks so much.
