This is called Brachytherapy.
Doctors can use radioactive isotopes to treat certain types of cancer, such as prostate cancer. Geologists use isotopes to date some rocks and fossils.
You can still treat thyroid cancer by using radiotherapy although I do not think its as effective. Alternatively, chemotheraphy could also be used.
Laser have been used to treat BPH. They are not generally used to treat cancer.
sealed radioactive source means the radioactive isotopes which is encapsulated with a stainless steel to avoid higher LET radiation condamination .typically source may be used in brachytherapy to treat the cancer and unsealed source used to in nuclear medicine which is the radioactive source is not sealed examble IODINE131
Radioactivity is indeed used to treat some types of cancer. Electron beams are used for surface cancers due to their lower energy. Proton beams and neutron beams are used to treat other hard to reach cancers. Carbon ion radiation is also sometimes used.
