  1. CANCER – Cell Division Gone Wrong • cells that grow and divide out of control • results in a change in DNA that controls the cell cycle. • prevents the cell from staying in interphase for the normal period of time. • the cell and its daughter cells will divide uncontrollably. • ..\Cancerous Cell Division.mht • YouTube - How cancer develops

  2. Tumours • Uncontrolled growth may create a rapidly growing mass of cells that form a lump, ortumour. • Tumours may bebenignor malignant. Cells in a malignant tumour are considered cancerous. • Cancer cells may break away from the original tumour and move to a different part of the body. • If they settle and grow in this new location, a new tumour will form. • This is called metastasis.

  3. Mutations • random changes that can occur in the cell’s DNA. • can result in the death of the cell or allow it to survive and continue to grow and divide. • If the cell cycle is abnormal, the cells may be cancerous. CARCINOGENS • environmental factors that cause cancer. • Ex: tobacco smoke, radiation, some viruses, certain chemicals, organic solvents… • Some cancers are at least partly hereditary. These include some breast cancers and colon cancers. • The Story of Cosmetics • http://www.cbc.ca/marketplace/2011/lousylabels/

  4. Super foods such as these help your body protect itself from cancers Cancer Risk Factors • Factors affecting a person’s risk of getting cancer include: • personal and family medical history • exposure to carcinogens in the environment • lifestyle choices, such as eating more “super foods” • exercise

  5. Cancer Screening • checking for cancer even when no symptoms are present. • by a doctor, such as a Pap testor blood test • genetic testing, when there is a familyhistory of cancer • at home, breast & testicle self examination • screening does not prevent cancer, but increases the likelihood of early detection and successful treatment.

  6. DIAGNOSIS • earlier the diagnosis the better chance of treatment • diagnostic imaging techniques include endoscopy, X-ray, ultrasound, CT scanning, and MRI. • a sample of the cells is removed and examined under a microscope. This is called a biopsy. Vocabulary Pap test

  7. Treatment • to slow down the growth of tumours or destroy as many cancer cells as possible. • Currently, there are three methods of conventional treatment: • surgery • chemotherapy • radiation therapy • One new technique to fight cancer is biophotonics, which uses beams of light to detect and treat the cancer cells.
