Civa C is a type of advanced radiation therapy used primarily in the treatment of cancer. It involves the use of small radioactive sources that are placed directly into or near a tumor. This method allows for a high dose of radiation to be delivered to the cancerous cells while minimizing exposure to surrounding healthy tissue. The technique is often used for tumors that are difficult to treat with traditional methods, such as surgery or external beam radiation. Civa C can be particularly effective for certain types of cancers, including those in the head and neck or breast, providing a targeted approach to treatment.
