1 Cell Division Gone Wrong
Cancer Cell Division Gone Wrong

2 Cancer Cancer is a group of diseases in which cells grow and divide out of control. The DNA that controls the cell cycle is mutated. (incorrect base pair sequence) Checkpoints in the cell cycle that stop cell division or kill the cell fail.


4 Tumours A tumour is a mass of cells that continues to grow and serves no function for the body.

5 Causes of Cancer Random mutations to a cell’s DNA base pair sequence
Carcinogens: Viruses (e.g. HPV, Hepatitis) Radiation (e.g. UV rays, X-rays)

6 Chemicals (e.g. tobacco smoke, cured meats)


8 Hereditary factors Can increase the chances of getting cancer, but do not guarantee cancer.

9 Cancer Screening Mammogram (for breast cancer)

10 PAP test (for cervical cancer)

11 Prostate Specific Antigen (PSA) Test (for prostate cancer)
The PSA test measures the blood level of PSA, a protein that is produced by the prostate gland. The higher a man’s PSA level, the more likely it is that he has prostate cancer.

12 Reducing the Risk of Cancer

13 Viewing Mitosis in Plant Root Tip
