Why do some cancer patients prefer brachytherapy? What is so unique about it?
Brachytherapy is considered an attractive option for many cancer patients, particularly in the treatment of certain types of cancer. This treatment modality precisely targets the tumor by placing a radiation source directly at the site of the disease. Brachytherapy offers distinct advantages over external radiation therapy, allowing many patients to better cope with their condition.
The most prominent advantage of brachytherapy is the localized treatment effect it provides, which allows high doses of radiation to be precisely directed to the tumor while minimizing damage to healthy tissue.
This treatment is not only suitable for cervical cancer, prostate cancer, and breast cancer, but can also treat a variety of other cancers, including esophageal cancer and skin cancer. Through brachytherapy, patients can reduce the impact of radiation on healthy tissue during treatment, reduce the chance of side effects, and increase cure rates.
How Brachytherapy Works
Brachytherapy involves placing an enclosed radiation source at or near the tumor in such a way that the radiation affects only a very localized area. This precise placement ensures that the radiation is effective in killing cancer cells without causing undue damage to surrounding healthy tissue.
This localized nature of radiation therapy makes it the best option in some situations, particularly for patients whose tumors are not easily accessible for surgery.
Brachytherapy can often be completed in a shorter time than other treatments, which not only helps improve your quality of life but also reduces the chance of cancer cells growing between treatments. Additionally, many times patients only have to come to the hospital a handful of times, which is a significant benefit for cancer patients who require regular treatment.
Safety considerations during treatment
Many patients are concerned about whether they need to take any special safety precautions towards people around them after receiving brachytherapy. For patients using improvised radiation sources, no radioactive material remains in the body after treatment, so close contact with family or friends will not cause harm. However, for some patients with permanent implants, they may be advised by their doctor to limit contact with children or pregnant women for a short period of time due to the low-dose radiation source that remains.
Clinical Application and Results
Brachytherapy is widely used in clinical practice and effectively covers a variety of tumor types. For example, for patients with prostate cancer, the use of permanent low-dose radiation implants can significantly reduce the chance of cancer recurrence. For patients with cervical cancer, the classic combination of external beam radiation therapy and brachytherapy can provide better treatment results.
Studies have shown that this treatment has comparable survival rates to surgery or external radiation therapy, but with fewer side effects, making it a popular choice for patients.
In the treatment of breast cancer, brachytherapy is often used as an adjuvant therapy after surgery, especially when it is necessary to achieve a good therapeutic effect while preserving the breast. By precisely delivering radiation, this approach effectively reduces the chance of damage to healthy breast tissue and reduces the number of overall treatments required.
SummaryOverall, the development of brachytherapy represents an important advance in cancer treatment, allowing patients to enjoy more focused, targeted care and faster recovery when receiving this type of treatment. As technology improves, brachytherapy is becoming more common, but is this option really a priority for patients in their fight against cancer?
