Cancer (Stomach / Oesophageal Cancer)

Cancer (Stomach / Oesophageal Cancer)

Broadly, cancer occurs when a cell in the body loses the ability to control its growth such that it grows and divides to form new cells uncontrollably. Normally the cells in our body have rules and ‘scripts’ to follow that include keeping the growth rate of cells controlled. If these ‘scripts’ become ‘unreadable’ by the cell (such as through a mutation in DNA which can occur any time a cell divides to create another cell) then the cell can keep dividing and creating new cells in an uncontrolled way. This is why a cancer causes a lump as it contains many more cells than normal (and they look different under a microscope). The uncontrolled growth also means there are now more chances for further mutations in the DNA scripts that control how a cell should behave. This can allow a cancer to spread to other parts of the body from where it would usually be found.
