Brachytherapy uses implanted seeds, wires or rods to attack cancer by delivering radiation inside the body, as close to the tumor as possible. The team at Lancaster General Health has extensive experience using high-dose and low-dose brachytherapy to treat:
- Prostate cancer
- Uterine cancer
- Cervical cancer
- Vaginal cancer
- Colorectal cancer
- Breast cancer
Placing the dose close to the cancer
Brachytherapy concentrates the radiation dose on the cancer cells. This allows for a high total dose of radiation over a short period of time with less damage to healthy tissue. The radioactive implants may be placed inside a body cavity or directly in the tumor.
Low-dose brachytherapy seeds, about the size of a grain of rice, are implanted permanently into the prostate. They are so small they can’t be felt, so they can be left in place permanently. The implants are placed during a short surgical procedure, which may require general anesthesia.
