Simulation on the emergence of metastases in breast cancer radiotherapy patients using Monte Carlo N-particle (MCNP)

The distribution of radiation doses in cancer patients who receive radiotherapy treatment depends on the distance cancerous organ to source, type including density and atoms organ. Even though exposure is focused that will be irradiated, surrounding healthy organs still have a great chance getting exposure. Healthy can exposed within certain period time are thought opportunity experience metastases. Simulation occurrence metastases around receiving has been done using Monte Carlo N-Particle (MCNP) simulations by ORNL- MIRD phantom model. simulation aimed at breast adding cells left depth 2.5 cm coordinates 8.63 - 9.5 46.87. results converted into dosimetry quantities describe impact organs. final measured dose effective dose. show patient’s body very wide, covering all under review, with highest rate value found as much 0.009079 Gy/s. received were lungs, 5.52 mSv followed breasts 5.28 mSv, it estimated lung considered large.
