What are different types of treatment of brachytherapy?
There are two main types of brachytherapy treatment: temporary and permanent. Temporary treatments include the location of the radioactive material in the tumor or close to the limited time before removal, while permanent treatment involves leaving radioactive material in the body and allows the natural level of radioactivity naturally. There are several possible variations in these two categories, both in the dose and in the location of the radiation source. The dose rate can be low, medium or high, or can be delivered in pulses. The location of the radioactive material can be interstitial, where it is inserted into a tumor or contact where it is located next to the tumor.
Brachytherapy can be given temporary by placing the radiation in the body or the radiation source can be left at the tumor site. A temporary treatment may be performed in a hospital or on an outpatient basis and radiation can be administered anywhere from a few minutes to days; These factors usually depend on the type and size of the cancer and the dose dose. During permanent treatmentBrachytherapy is small radioactive seeds placed in or near the tumor, where the amount of radiation they give slowly decreases over time until almost nothing is.
different types of cancer usually require different doses of brachytherapy. Oral cancer and sarcomas are often treated with low dose or LDR, as well as prostate cancer, which is often best addressed with permanent LDR seeds. Other cancer, such as lungs, breasts and cervix, are more suitable for temporary treatment at high dose or HDR. Another option is the speed of the dose or PDR, where short explosions of radiation at measured intervals are applied to the tumor.
Other variations in Yytherapy Brachléča is a place where the radiation source is located in relation to the tumor. It can be placed directly in targeted tissue, which is a procedure known as interstitial brachytherapy. This technique is common for the treatment of tumors on soof places such as prostate or breasts. The second option is contact brachytherapy, where the radiation source is inserted in close proximity to cancer. This can be achieved by placing in the body cavity, blood vessel or tubular organ, such as the trachea, or by external placement on the skin near the tumor.
