My Daughter age 18 has Cowden Syndrome. She had thyroid cancer at 16 and had her entire Thyroid removed. She has had a cough, tightness in her throat and chest, shortness of breath, choking and her voice has become very hoarse, deep for approximately 3 months. They have tried antibiotics, inhalers, nebulizer treatments, oral steroids and nothing is working. Do you think it is reasonable to ask for her to be screened for lung cancer?
