Can cancer be detected through a blood test?

  • Hi Varsha,

    Blood tests are used to detect certain cancers like those of blood cells. Certain cancers of body organs are detected by detection of tumor markers which are released by cancer cells into the blood. Cancers of Ovary, Colon, Prostate are commonly initially detected by blood tests. Blood tests are also done to detect recurrence of these cancers.

    Cancer is most commonly confirmed by tissue diagnosis which is obtained through biopsy or FNAC.
