Can you hit the tumour? Help X-Ray-Boy and Beam Girl fight the cancer!

If a person gets cancer, unwanted tumour tissue can grow uncontrollably inside their body, harming healthy organs and making that person sick. Luckily, we can treat and even cure the patient with the help of physics! Did you know that ionizing radiation is like a superpower to eliminate tumour tissue? Using special accelerator machines, medical physicists shoot radiation precisely to the tumour, while minimizing the harm to the surrounding healthy tissue and organs. See for yourself how cancer patients are treated with radiotherapy and how physicists make sure they hit the tumour correctly.
