Cancer

I can explain how a cancerous tumour is formed and identify some risk factors that increase the likelihood of a person developing cancer.

Lesson details

Key learning points

  1. Cancer is a non-communicable disease.
  2. Cancer is when cells divide uncontrollably and form a tumour.
  3. Tumours can be benign or malignant.
  4. Scientists have identified risk factors for certain cancers, including lifestyle and genetic factors.
  5. Infection with the sexually transmitted infection HPV can increase the risk of cervical cancer.

Common misconception

There is nothing a person can do to decreases their risk of getting cancer.

Although we can't change inherited genetic risk factors for cancer, it does also have many associated lifestyle risk factors such as obesity and smoking.
