Topic: Cancer

Part 1 - Keywords:

1. Cancer

2. Benign tumours

3. Malignant tumours

4. Uncontrolled growth

5. Metastasis

Part 2 - Key Facts:

• Cancer is the result of changes in cells that cause uncontrolled growth and division.

• Benign tumours are abnormal cell growths contained within one area and usually enclosed in a membrane. They do not spread to other parts of the body.

• Malignant tumours, or cancers, invade nearby tissues and can spread to different parts of the body through the bloodstream, forming secondary tumours.

• Lifestyle factors, such as diet, smoking, and exposure to radiation, are associated with various types of cancer.

• Genetic factors also contribute to the risk of developing certain types of cancer.
