Cell Division Gone Wrong….

What is cancer? Mitosis- normal cell division Cancer- uncontrolled cell division (carcinoma) –Develops into a tumor Benign- does not spread –(Not Cancerous)

Cancer Over the last decade, improvements in early detection and treatment of cancer have resulted in improved survival and a decline in mortality for.

Groups of 100 diseases that develop across time. Characterized by uncontrolled cell division. Can develop in virtually any of the body’s tissues. Hereditary.

CANCER : Is a growth that happens because of uncontrolled cell division (mitosis) These changes are caused because of damage to genes in DNA. Cancer can.

Mitotic Index & Cancer. Mitotic Definition The mitotic index is the ratio between the number of cells in mitosis in a tissue & the total number of observed.

Cancer Objective What is Cancer? Cancer is uncontrolled cell growth. (Mitosis) When you are young, your cells grow fast so because you are growing.

Mitosis & Cancer. What is Cancer? Mutated cells that are not longer under control Cancer Cells Grow uncontrollably Multiply more rapidly than normal cells.

 Our bodies are made of cells, which grow, work, reproduce and die  Genes control when cells grow, work, reproduce and die  Normally, cells obey these.

CELL DIVISION GOING WRONG: Cancer When cells grow and divide out of control, they cause a group of diseases called cancer.cancer The result is a change.

Cancer Mitosis Gone Wild

What is it?? Uncontrolled, unregulated growth of cells Cell division happens much more rapidly

Cancer cells often look much different then regular cells

Tumours and Cancer Tumours can be either benign (non-cancerous) or malignant (cancerous). Benign tumour cells stay in one place in the body and are not usually life-threatening. Malignant tumour cells are able to invade nearby tissues and spread to other parts of the body. Cancer cells that spread to other parts of the body are called metastases.

Normal cells versus Cancer cells Usually only divide to replace damaged cells Cell to cell communication Cannot divide in isolation Adhere to one another Can differentiate Uncontrolled cell division Do not need to communicate with each other Can divide in isolation Can metastasize (through circulatory and lymphatic) Can not differentiate

Cancer in Young Adults Approximately 10 000 cancers are diagnosed in young adults each year Cancer is the main cause of early death among young adult women More young women then young men are now diagnose with, and die from, lung cancer Testicular cancer is the most common cancer in young men

Causes of Cancer Causes are still not really understood Carcinogens are chemicals that cause cancer by causing mutations Lifestyle habits (diet, tanning, tobacco, alcohol, radiation, occupational hazards) Environmental triggers Family history

Journal Assignment Due on Thursday Marked out of 20 points 3 Parts to include in your journal Fully explain the connections between mitosis and cancer. (5 pts) Why is it important to learn about cancer? (5 pts) How has affected you in your life? (5 pts) Also include vocab words: metastasize, benign, and malignant somewhere in your entry (5 pts)
