The advantages of tumor radioactive particle implantation are targeting and less damage to local tissues, while the disadvantages are radioactive residue after treatment and incomplete treatment.
1. Advantages: The starting dose of particle implantation is lower, less damage to the surrounding normal tissues, and better targeting. It has excellent therapeutic effect on tumors with slow and limited proliferation (≤7cm), especially suitable for prostate cancer and pancreatic cancer.
2. Disadvantages: The radioactive material implanted during particle implantation has a longer half-life in the body than that of external radiation, so the radioactivity of the particles may affect the patient and the surrounding population in a short time during the treatment. In addition, for tumors that are too large, the implantation range may be insufficient, and the tumor cells may not be killed completely, resulting in poor results.
Specific radiation dosage and treatment plan are recommended for patients to communicate with their doctors in detail and choose the appropriate treatment method to get a better prognosis.
