Reducing the Risks

Slide 2

Learning Objectives

• How to keep healthy and to know what influences health.

• To know that food is used as a fuel during respiration to maintain the body's activity and as a raw material for growth and repair

Slide 3

Learning Outcomes

• Know what causes pre cancerous cells

• Know what causes them to begin to grow and spread

• Know what can help to prevent cancer

Slide 4

Definition of Cancer• Cancer is a class of diseases characterized

by uncontrolled cell division and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue (invasion) or by migration of cells to distant sites (metastasis). This unregulated growth is caused by a series of acquired or inherited mutations to DNA within cells, damaging genetic information that define the cell functions and removing normal control of cell division. ...

OR put another way….

• It is like the breakdown of law and order in the cell which, if it isn’t policed (the immune system’s job) and dealt with, lawlessness and disorder can start to spread to other cells and other areas. Systems then begin to collapse and anarchy reigns (cancer rules)!

Slide 6

Facts

• The number of new cases annually is estimated to rise from 10 million to 15 million by 2020.

• Cancer accounts for 7.1 million deaths annually (12.5% of the global total).

• Dietary factors account for about 30% of all cancers in Western Countries and approximately up to 20% in developing

• Approximately 20 million people suffer from cancer; a figure projected to rise to 30 million within 20 years.

Slide 7

Body facts about Cancer • It is thought that we have around 100,000, 000, 000, 000

cells, in our body, give or take a few! • There are over 200 types of cancer • We make between 200 and 1000 pre cancerous cells

everyday (immune system remove them)• There is no single cause of cancer it is a combination of

occurrences/incidences, “it is a multi stage process”.• Therefore there is no single treatment • Although every cancer is unique to that person there can

be similarities• Scientists still don’t know what causes most cancers

How to reduce the risks of Cancer? Slide 12

1. Keep your environment as free from pollutants as possible

2. Put in substances that help strengthen the immune system like vitamins, minerals and antioxidants from your diet

3. Drink plenty of water to help remove toxins from the body and eat fibre also to help remove toxins

4. Exercise!

How to help beat Cancer Slide 13 • Strengthen the immune system (do everything from

the previous slide but even more so)

• Surgery and or

• Radiotherapy and or

• Chemotherapy

• Ultrasound/Hormonal/Complementary etc
