Final answer:
Physicians involved in transrectal seed implantation for prostate cancer treatment include radiation oncologists and urologists, with the occasional involvement of pathologists. Medical oncologists are not typically involved in this specific procedure, making them the correct response to the question.
Step-by-step explanation:
Transrectal seed implantation is a procedure used for prostate cancer treatment, which involves the placement of radioactive seeds or pellets into the prostate. These seeds then deliver radiation directly to the prostate with the aim of killing cancer cells. The procedure is also known as brachytherapy.
The medical professionals typically involved in brachytherapy for prostate cancer include radiation oncologists, who design and oversee the radiation treatment plan, and urologists, who are responsible for the surgical aspects of seed implantation. Pathologists may also be involved in diagnosing the cancer and determining its stage and grade.
However, medical oncologists, who specialize in the medical treatment of cancer using chemotherapy, immunotherapy, and targeted therapy, are generally not involved directly in the procedure of transrectal seed implantation for prostate cancer.
Therefore, the physicians involved with the treatment include all EXCEPT medical oncologists.
