ways to detect cancer

endoscopy

Fibre optic cable is inserted into the body cavity to look for suspicious growths, commonly used to detect colon cancers.

x rays

Images used to detect cancer in bones and lung tissue; a mammogram is a specialised x-ray to examine breast tissue.

ct/cat scan

X-ray images taken from various angles to assess hard-to-see tissues, often used to detect brain cancer.

mri

Radio waves and magnetic fields generate 3D images with greater detail than CT scans.

examining cells and biopsy

Cells are taken via blood samples or surgery and examined under a microscope; cancer cells can be identified by their shape and size.
