Topic; cancer and cell division

QUESTIONS
1. What type of cells cause cancer? ANSWER-**Cancer cells** are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. 2. How fast do cancer cells divide? ANSWER-Cancer cells grows faster than normal cells. They also never die off on their own. Cancer cells begin to divide at a faster speed than regular cells. These cells will continue to divide until they begin to form a mass that is known as a tumor. The faster the cells divide the larger the tumor will become in size. 3. Why is cancer so comon? ANSWER-It is not one disease; there are over 200 different types, each with its own symptoms, methods of diagnosis and treatment. 4. How fast does a blood cell travel? ANSWER-One source quotes the normal range for the carotid artery as 28.6-178.4 cm/sec. This converts to 0.64 to 4.0 mph. 5. Do cancer cells divide like normal cells? ANSWER-Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, when the repair work is done, cells are no longer reproduced to fill in the hole. In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed. 6.Can stem cells help find a cure to cancer? ANSWER-In a typical stem cell transplant for cancer very high doses of are used, often along with therapy, to try to destroy all the cancer cells. 7. can cells division cause a cell to mutate? ANSWER-Most of the mutations that we think matter to evolution are "naturally-occurring." For example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 8. Why is cell division so imprtant? ANSWER-The three main reasons why cell division is important are; growth, reproduction,and repair 9. Does cell divsion help cause or cure cancer? ANSWER-Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). 10. Do cancer cells all look differnt? ANSWER-This is because they are formed by different cell types and because the cells are arranged differently. Even more importantly, it was discovered that the usual appearance of each type of tissue or organ is changed by diseases like cancer.
