The Thyroid Nodule and Cancer Guide is a powerful app that educate patients (and doctors) in the analysis of thyroid nodule(s). The app provides a 3D picture of what your thyroid looks like and how thyroid nodules are growing over time. The app provides thyroid cancer risks and the potential need of biopsies and even thyroid surgery based upon your own data. The app will analyze blood tests, ultrasound evaluation of the thyroid gland and lymph nodes, needle biopsy and genetic analysis results, and other thyroid cancer related issues. The app requires a thyroid ultrasound or CAT scan to work. The app is for thyroid nodules and cancer; it is not for hyper-thyroid or hypo-thyroid.
