Radiation Oncology

Brachytherapy is a form of internal radiation treatment in which a radioactive source is placed inside or close to the tumor. Because the radiation is delivered near the target, it can provide a high dose while limiting exposure to surrounding tissues. It is commonly considered for selected cervical, prostate, breast, and other cancers. Technique and safety precautions depend on the treatment site and source used.

Treatment Planning Process

Treatment begins with consultation and diagnostic review. A planning CT scan is usually performed with the patient positioned as they will be during treatment. Immobilization devices may be used to help maintain consistent positioning. The radiation oncologist identifies the tumor and nearby organs at risk. Physicists and dosimetrists develop and check the plan. Image guidance and quality assurance support safe delivery.

What Happens During Treatment?

Most external-beam radiation sessions are painless. Patients lie on a treatment table while the machine delivers radiation from outside the body. Radiation delivery takes only a few minutes, while positioning and image verification may take longer. Many treatment schedules involve sessions from Monday to Friday over several weeks, while selected stereotactic treatments may require only a few sessions. Brachytherapy follows a different schedule based on the cancer and treatment plan.

Benefits of Radiation Therapy

Radiation can provide benefits when selected. It can help cure certain localized cancers, reduce the risk of cancer returning in a treated area, preserve the function of some organs, and relieve symptoms caused by advanced disease. Precision techniques can also help reduce unnecessary radiation exposure to nearby healthy structures. Benefits depend on diagnosis, stage, treatment goal, and patient factors.

Possible Side Effects

Side effects vary by treatment area, dose, schedule, and individual response. Fatigue is common during treatment. Some patients may develop skin redness, dryness, or irritation in the treated area. Radiation involving the mouth or throat can cause mucosal discomfort or swallowing difficulties, while treatment involving the abdomen or pelvis may cause bowel or urinary changes. Hair loss generally occurs only in the area receiving radiation. The team monitors symptoms and provides supportive care.

Recovery and Follow-Up

Many patients continue daily activities during radiation, although energy levels may change as treatment progresses. Side effects can develop gradually and may briefly increase after treatment. Patients are usually given guidance about skin care, nutrition, hydration, rest, and activity. Follow-up appointments help assess recovery and monitor treatment response. Follow-up tests are scheduled according to the cancer type and treatment plan. Long-term surveillance helps detect recurrence and manage lasting effects.
