Abstract:

Multiple primary malignancy (MPM) are two or more primary tumors that are diagnosed simultaneous or metachronous. The incidence of MPM rise with advanced age and is more common in men despite the high incidence of prostatic cancer and its co-occurrence with other type of cancer [2]. In a study of 1 104 269 patients with cancer the reported prevalence of MPM was 0.73% to 11.7%. Patients with cancer diagnosis have 20% more risk of having a second malignancy, compared with those that were never diagnosed
