Final answer:
Increased calcium and an M spike can indicate multiple myeloma, a type of cancer that affects plasma cells in the bone marrow.
Step-by-step explanation:
Increased calcium and an M spike can indicate Multiple myeloma. Multiple myeloma is a type of cancer that begins in the plasma cells of the bone marrow. Plasma cells are a type of white blood cell that produces antibodies to help fight off infections. In multiple myeloma, the abnormal plasma cells multiply and accumulate in the bone marrow, leading to the production of excessive amounts of a monoclonal protein, also known as an M spike.
This excess protein can cause various symptoms and complications, including bone pain, fatigue, kidney problems, and an increased risk of infections. Blood tests showing increased levels of calcium and the presence of an M spike can help diagnose multiple myeloma.
It is important to note that increased calcium levels can also indicate other conditions, such as hyperparathyroidism or certain bone disorders like osteoporosis. However, when combined with an M spike, it is more likely to be indicative of multiple myeloma.
Other options such as hypocalcemia, osteoporosis, and hyperparathyroidism are related to calcium metabolism but do not typically present with an M spike. Hyperparathyroidism specifically results in hypercalcemia, but not an M spike.
Moreover, in the context of hyperparathyroidism, increased bone deposition does not occur; rather, the condition can lead to fractures due to decreased bone density. Hyperparathyroidism is characterized by excessive release of parathyroid hormone (PTH), ultimately leading to high serum calcium levels, low serum phosphate, and bone resorption.
