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.
Thyroid nodules may be single or multiple. A thyroid gland that contains multiple nodules is referred to as a multinodular goiter. If the nodule is filled with fluid or blood, it is called a thyroid cyst. If the nodule produces thyroid hormone in an uncontrolled manner (without regarding the body's needs), the nodule is referred to as autonomous.
