Frequent question: Does the body recognize cancer cells?

·

Can cells detect cancer?

And, unlike normal cells, cancer cells can metastasize (spread through blood vessels or lymph vessels) to distant parts of the body, too. Knowing this helps doctors recognize cancers under a microscope, because finding cells where they don’t belong is a useful clue that they might be cancer.

Can your body fight cancer on its own?

Cancer is traditionally treated with surgery, chemotherapy, and radiotherapy. But a number of studies in recent years have demonstrated that our own body might be able to fight the disease, using the immune system to target and kill cancer cells.

How does the body recognize cancer cells?

Dying cancer cells release tumor-specific antigens. These allow the immune system to recognize that the tumor cells are different from normal body cells. Immune cells, such as dendritic cells or macrophages, take up the released antigens and travel to the lymph node.

Do blood tests show cancer?

With the exception of blood cancers, blood tests generally can’t absolutely tell whether you have cancer or some other noncancerous condition, but they can give your doctor clues about what’s going on inside your body.

Does cancer show up in routine blood work?

New research suggests that a routine blood test could help find cancers early. Researchers have previously shown that high levels of platelets – cells in the blood that help stop bleeding – can be a sign of cancer. But now they have found that even slightly raised levels of platelets may be an indication of cancer.
