My doctor tells me this is not a reason for concern and will go away. I have history of cancer in family(breast cancer and cervical). My tsh levels are normal. I am deficient in vitamin D and high cholesterol not diabetic but close to be. should I follow up with other testing? I did an ultrasound already showing the nodular mass
