What is cancer?

Cancer begins to form when cells in the body start to multiply in an uncontrolled way. This can then form a lump or swelling (a tumour) or affect the way cells work for example, blood cancers. Cancer is not just one disease. There are now over 200 different types of cancer, all with different signs and symptoms.

Benign or malignant tumours  - what does this mean?

  • Benign tumours – are usually harmless and don't always need treatment
  • Malignant tumours – are cancer and will usually need some form of treatment

Primary and secondary cancer

Cancer may be described as primary or secondary:

  • Primary cancer – where the cancer starts
  • Secondary cancer – when a primary cancer has spread to other parts of the body. It is also called metastatic cancer.

Research

Research into cancer is evolving and new ways of treating and preventing cancer is being discovered all the time.
