second primary cancer meaning

• [Medicine]
  Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.

• Those who survive cancer develop a second primary cancer at about twice the rate of those never diagnosed.
• Furthermore, since AYA survivors are diagnosed and treated at such a young age, their length of time being a survivor is much longer than their adult counterparts, making it more likely they will face a second primary cancer in their lifetime.
• It is believed that AYAs have a much higher relative risk of developing a second primary cancer because the intensity of the treatment for their original diagnosis, typically including any combination of chemotherapy, surgery, and radiation, is much higher than the level of intensity given to patients over 40.
