A low white blood cell count is a common side effect of some cancers and cancer treatment. When your white blood cell count is too low, you have a high risk of getting an infection. Infections can be very serious in people with cancer.
Thyroid nodules are lumps which commonly arise within an otherwise normal thyroid gland.
Up to 4% to 8% of adult women and 1% to 2% of adult men have thyroid nodules detectable by physical examination. Closer to 30% of adult women have nodules detectable by ultrasound. In fact, diagnosis of a thyroid nodule is the most common endocrine problem in the United States. Although the majority of thyroid nodules are benign (not cancerous), about 10% of nodules do contain cancer. Therefore, the primary purpose for evaluating a thyroid nodule is to determine whether cancer is present.
