(57) Abstract :
An oncology therapy method comprises implanting a radioactive seed (10 20 30 40 50) in an oncology subject (S). In some
embodiments the radioactive seed comprises a radioactive material (12 32 33 42) including at least one radioisotope disposed in
a biodegradable host (14 24 25 44) configured to biodegrade over a therapy time period when implanted in the oncology subject.
In some embodiments the radioactive seed is implanted in soft tissue of an oncology subject (S) and the radioactive seed
comprises a radioactive material (12 32 33 42) including at least one radioisotope disposed in a host material (14 24 25 44)
having softness comparable with or softer than the soft tissue into which the radioactive seed is implanted.
