The rate of male breast cancer has increased in
recent years, due to the deficiency of preventive examinations (male
mammography). Besides, since male breasts are generally smaller than
female breasts, it is essential to monitor the doses received by male
breasts, as well as those received by close, healthy and critical organs
in order to assess the plan used in this kind of treatment. To do this,
the distribution of doses in male breasts was simulated and assessed,
based on the procedures adopted in the treatment of female breasts, when
submitted to a radiation beam from a linear accelerator. The Alderson
Rando phantom was used and the relevant absorbed doses were measured by
TLD-100 thermoluminescent dosimeters distributed throughout the volume
of interest. The results of the treatment planning were compared with
the results obtained by TLDs. A difference of up to 8.5%, in comparison
with the planned dose, as well as a 6% relative standard deviation was
found.
