Question

The presence of which chemical in the blood can indicate that cancer exists somewhere in the body? ​

Quizplus · Accepted Answer

HCG (human chorionic gonadotropin) is a hormone that is produced by some cancer cells, such as testicular cancer and ovarian cancer. Therefore, elevated levels of HCG in the blood may indicate the presence of cancer in the body. The other options (aldosterone, interleukins, cytokines, and thyroxine) are not specifically associated with cancer diagnosis.
