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.
