Receiving a diagnosis of advanced cancer requires a thorough understanding of available clinical interventions. Medical professionals use various treatments to target cancer cells, and radiation therapy is an effective option. Here is more information on radiation therapy and its application in advanced stages of the disease:
What Is Cancer?
Cancer develops when abnormal cells divide uncontrollably within the body. These cells can infiltrate normal body tissues, sometimes spreading throughout the body via the bloodstream or lymphatic system. The cellular changes originate from DNA mutations, and medical providers typically identify these growths as tumors.
What Are the Different Types?
Medical professionals categorize cancer by the tissue type from which the abnormal cells originate. Carcinomas begin in the skin or tissues lining internal organs, and sarcomas develop in bone, cartilage, fat, muscle, or blood vessels. Leukemias start in blood-forming tissue, such as the bone marrow. Lymphomas and multiple myelomas originate in the cells of the immune system.
Central nervous system cancers start in the tissues of the brain or spinal cord. Advanced cancer indicates that the disease has spread from its original site to other parts of the body. Doctors may refer to this stage as metastatic cancer, and it requires specialized systemic or localized treatments. The specific type of cancer dictates the chosen medical approach.
What Is Radiation Therapy?
Radiation therapy is a clinical treatment that uses high doses of radiation to kill cancer cells. The high-energy beams damage the DNA of the targeted cells, and this damage stops the cells from growing or dividing. Medical teams carefully calculate the dosage to maximize the impact on cancer cells while sparing healthy tissue.
Oncologists use this therapy to shrink tumors before surgery or to treat the remaining abnormal cells after surgical removal. It serves as a primary treatment for some patients, or doctors may combine it with chemotherapy. In external beam radiation therapy, the radiation comes from a machine outside the body. Internal radiation therapy places a solid radiation source directly inside the body near the tumor.
What Does It Involve?
The process begins with a consultation and a detailed planning session. During planning, the medical team determines the exact positioning of your body, and they use imaging scans to map the tumor’s precise location. Patients lie on a treatment table while a technologist marks the targeted area on the skin. These marks guide the alignment of the radiation machine during subsequent sessions.
The patient remains still while the machine delivers the calculated radiation dose. Patients undergo regular evaluations throughout the entire treatment timeline to monitor their physical response. The oncologist may schedule periodic imaging tests, and these scans assess the tumor mass’s shrinkage. Adjustments to the radiation dosage occur if clinical data indicate a necessary change.
What Are the Benefits?
Radiation therapy provides localized treatment that targets specific areas without affecting the entire body. It effectively shrinks large tumors in advanced stages of cancer, and this reduction can relieve pressure on surrounding organs or nerves. Shrinking tumors may reduce pain and improve the patient’s overall comfort. The therapy can be used independently or alongside other medical interventions, with patients benefiting from customized treatment plans designed around their specific medical needs.
