  3. Progeria

  4. Hypertrichosis

  5. Proteus syndrome

  6. Cancer  A broad group of diseases that result in uncontrolled cell division.

  7. Cancer • Why does it keep dividing? • The cells checkpoints might fail to identify problems or kill off the cell. As a result...

  8. Cancer • Tumour – a rapidly growing mass of cells

  9. Cancer • Benign tumour – the cells stay together and have no serious effect on surrounding tissues. • Malignant tumour – the cells interfere with the function of neighbouring cells and tissues Malignant tumour Benign tumor

  10. Cancer • Metastasis – occurs when cancer cells break away from the original tumour and move to a different part of the body.

  11. Causes of Cancer • 1. Mutations – random changes that occur in the DNA while it is being duplicated.

  12. Causes of Cancer • 2. Carcinogens – are environmental factors that cause mutations. • Tobacco • Plastics • Radiation • X-rays • Sunlight

  13. Smoking and Cancer • What else does smoking affect?? • Lungs • Lips • Tongue • Fingers • Trachea • Throat

  14. Causes of Cancer • 3. Some cancers can be hereditary depending on whether or not you obtain that portion of DNA from your parents. • Ex. Breast cancer, colon cancer

  15. Causes of Cancer • 4. Infections & Viruses • Virus enters cell and ‘highjacks’ it to reproduce • Some viruses insert their own DNA inside the host cell, causing it to become cancerous

  16. Cancer Screening • This involves checking for cancer even if there are no symptoms. • This is important to catch cancer at an early stage. • ABCD (asymmetry, border, colour, diameter)

  17. Cancer Fighting ‘Super Foods’
