Cancer Cells and Radiation By Dominika Cornejo

What is Radiation Therapy? Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Other names for radiation therapy are radiotherapy, irradiation, or x-ray therapy.

How Does Radiation Kill Cancer Cells? Radiation therapy kills cancer cells by damaging their DNA This can be achieved by either direct damage to the DNA or by creating free radicals within the cells that damage the DNA A cancer cell can’t grow or divide anymore when its genes are damaged by radiation Over time the cell dies

Types of Radiation Therapy External-beam radiation therapy Delivered by a machine outside of the body Internal radiation therapy (brachytherapy) Radioactive material is placed inside the body near cancer cells Systematic radiation therapy Radioactive material travels through the body and is absorbed by cancer cells Can be given in one of three ways: By mouth-a capsule or solution By intravenous injection-radioactive material is injected directly into a vein By instillation-the radioactive material is placed into a body cavity

Equipment Needed CT Scans (MRI, PET Scans, and Ultrasounds are sometimes taken as well) A head mask during the scan is also provided to prevent the movement of the patient’s head Varian Trilogy Linear Accelerator with on-board imaging (OBI) Optical guidance system, respiratory gating Stereotactic radiosurgery/radiotherapy (SRS/SRT) Electronic portal imaging 120 Multi-leaf Collimator (MLC)

Side Effects Side effects depend on a number of factors: area of the body being treated, the dose given per day, the total dose given, the patient’s general medical condition, and other treatments given at the same time Possible side effects: Skin irritation Hair loss Urinary problems Salivary gland damage Fatigue Nausea (with or without vomiting) Fibrosis Damage to the bowels (causes diarrhea and/or bleeding Memory loss Infertility Development of a second cancer due to radiation exposure (Rarely happens)
