Radiation Therapy

During radiation therapy, a team led by a radiation oncologist—a specialist in this treatment—will carefully plan and supervise your treatment. Each session typically involves directing high-energy radiation toward the cancer cells using specialized equipment. This targeted exposure fractures the DNA within the cancer cells, making it difficult for them to grow and multiply. While healthy surrounding cells may also be exposed to some radiation, most can recover and continue functioning normally, whereas cancer cells generally cannot.

At El Portal Comprehensive Cancer Centers, we utilize the latest and most advanced radiation technologies to minimize exposure to healthy cells. Our accredited equipment undergoes daily checks to ensure the highest level of precision in treatment.

There are two main categories of radiation therapy:

External Beam Radiation Therapy

This method delivers radiation from a machine outside the body, directing beams specifically at the cancer site. The equipment does not physically contact the body and can be adjusted to deliver radiation from multiple angles. Treatment typically occurs five days a week for a duration ranging from 1 to 10 weeks.

Technologies may include:

• TrueBeam Radiotherapy:Offers advanced options tailored to your specific anatomy and cancer type.
• Image-guided Radiation Therapy (IGRT):Uses imaging (such as CT or ultrasound) to accurately direct radiation.
• Intensity-modulated Radiation Therapy (IMRT):Shapes radiation beams around tumors while sparing surrounding healthy organs.
• Stereotactic Radiosurgery (SRS):A non-invasive approach treating irregularly shaped tumors, particularly in the brain.
• Stereotactic Body Radiation Therapy (SBRT):Similar to SRS, but designed for tumors outside the skull.
• Hypofractionated Radiation Therapy:A specialized technique for breast cancer treatment, depending on individual patient factors.

Internal Radiation Therapy

Internal radiation therapy, or brachytherapy, involves placing radioactive material directly inside or near the tumor. This may include various implants such as pellets, seeds, or tubes, which are inserted using minimally invasive methods.

At El Portal Comprehensive Cancer Centers, we offer:

• High-Dose Rate (HDR) Brachytherapy:Often utilized for uterine or cervical cancers, this approach involves placing radioactive material for short durations multiple times.
• Selective Internal Radiation Therapy (SIRT):An innovative, non-surgical procedure for liver tumors, delivered via tiny radioactive beads inserted directly into blood vessels leading to the tumor.

After a cancer diagnosis, you will likely be referred to a cancer specialist, such as a surgical oncologist or medical oncologist. Your treatment plan, which may include radiation therapy, is tailored uniquely based on:

• Type and grade of cancer
• Size and location of the tumor
• Sensitivity of surrounding tissue
• Genetic components
• Family history
• Age, overall health, and medical background
• Personal treatment goals and preferences

Your doctor will also consider whether you have previously received radiation to that area, as each body part has a safe lifetime dose of radiation. The decision to proceed with radiation for recurrence depends on the location of the tumor, cancer type, and past radiation exposure.

Radiation therapy may be recommended as a standalone treatment or in conjunction with surgeries, chemotherapy, or immunotherapy. At El Portal Comprehensive Cancer Centers, we typically can schedule your first appointment within two days of your referral.

Radiation therapy demands a high degree of skill, precision, and experience. Selecting a provider with state-of-the-art technology and strict protocols ensuring equipment accuracy is essential.
