Background: The study's objective was to estimate the effects of radiation on testosterone-related hormones and blood components in prostate cancer patients. N Materials and Method: This study aims to investigate the effects of radiation on 20 male prostate cancer patients at the Middle Euphrates Oncology Centre. Blood samples were collected before and after radiation treatment, with a total dose of 60- 70 Gy, The blood parameters were analyzed. The hospital laboratory conducted the blood analysis using an analyzer (Diagon D-cell5D) to test blood components before and after radiation. Hormonal examinations included testosterone levels, using the VIDASR 30 for Multiparametric immunoassay system Results: The study assessed the socio-demography of prostate cancer male patients, revealing that the majority were aged 69.55 t 10.76 years, with a weight of 75.3 t 10.84 Kg and height of 170.50 t 8.70 cm. The stage of cancer was assessed, with 25% of patients being IV and IIV, followed by II, IB, and V. Only one patient was at stage III. The Gleason Score (GS) was used to classify patients, with 40% being given a score of 7, followed by 6, 8, and 9 equally (20%). Total Prostate-specific Antigen (PSA) had a mean value of 12.87 t 2.78. Hematological analysis showed a significant decrease in random blood sugar levels, white blood cells, lymphocytes platelets, and hemoglobin levels after radiotherapy. Testosterone levels also declined after radiotherapy fractions. However, kidney functions like urea and creatinine levels increased after pelvic irradiation Conclusion: The study found that radiation treatment for prostate cancer significantly impacted blood components and hormones associated with testosterone. It led to reduced levels of random blood sugar, white blood cells, lymphocytes, platelets, haemoglobin, and testosterone. Additionally, high-energy therapeutic x-rays increased_ levels of urea and creatinine, indicating the need for strict monitoring and management of adverse effects.
