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.
Most commonly, these cancerous nodules will be a specific type of thyroid cancer derived from the thyroid gland itself; hence they are referred to as primary thyroid tumors. Less frequently, a nodule may represent spread of cancer from elsewhere in the body (metastatic or secondary cancer).
