1. MITOSIS GONE WRONG-CANCER
• ncontrolled, unregulated growth of cells
• cells divide at a much faster rate than normal cell
The diagram illustrates a skin melanoma

2. What are Key Terms Associated with Cancer
Malignant tumour- cancerous tumour
Benign tumour (non cancerous tumour)
Metastasis-spreading of cancer through lymphatic/circulatory system
Oncogene- a gene that is linked to cancer
Oncologist- a doctor who treats cancer patients
Biopsy- a sample of tissue that is taken from the body
Oncolytic Virus- a virus that can treat cancer by destroying cancerous cells

3. some cancers grow very slow and may even stop for years
Cancer cells can divide on their own (unlike normal cells)
some cancers grow very slow and may even stop for years
don’t stick well to other cells -> spread! -> metastasis –
(Terry fox  leg to lungs even after amputation)

4. How do Normal Cells Look Compared to Cancer Cells? Shape, size, nucleus

5. How does the Cell Cycle look in Cancer Cells
How does the Cell Cycle look in Cancer Cells? Chemotherapy affects all cell growth not just cancer cells (affects different parts of cell cycle)

6. Cells don’t specialize and therefore can’t do their job
General Characteristics of Cancer
Cells don’t specialize and therefore can’t do their job
definitive diagnosis usually requires the examination of tissue which is obtained by biopsy or surgery
diagnosed, cancer is usually treated with surgery, chemotherapy or radiotherapy or oncolytic viruses (still in research phase)

7. What are Some Signs of Skin cancer?
1. irregular border
2. large
3. Strange colour
4. Asymmetrical
5. Its changing

9. What are some Common Causes of Cancer ? SEPTEMBER 27th
Genetic factors (colorectal, breast etc)
Carcinogen (cancer causing agents –environmental etc)
Radiation exposure
Ultraviolet B radiation from the sun
Various chemicals in cigarettes
Asbestos fibres (when released)
High fat, salt and sugar diets (liver, stomach, esophageal)
HPV (human papilloma virus)-linked to cervical cancer
