Cells can sense when to start dividing or stop dividing?
Cells have mechanisms that sense signals from their environment to determine when to start dividing (such as growth factors) or stop dividing (such as DNA damage or contact inhibition). These signals help regulate the cell cycle and ensure proper cell division. Dysregulation of these processes can lead to diseases like cancer.
How was cancer created?
Cancer was not created, it is a disease. It is caused by cells growing in a mass and not doing anything else. It crowds out cells that are trying to do their jobs. It can also give off poisons. It can start to bleed. It results when a chromosome in the cell becomes misformed or an incorrectly formed chromosome becomes active. The chromosome may be in the nucleus or the mitochondria. The cell divides and creates identical cells and the cells keep dividing.
Is Liver cancer a class A cancer?
yes it dos start from your cells
How easy is it to get cancer?
You can get cancer just by smoking.You have cancer cells in your body pretty much from birth - The problem comes when they form an abnormal growth which is what is generally referred to as a 'cancer'.Certain things can encourage this change in the cells to start growing abnormally, chemicals in cigarette smoke are an obvious example, injuries can sometimes spark it off too.Hope this helps.
Do all cells grow and divide at the same time?
Most cells do not continuously divide. These cells enter the G0 phase of the cell cycle after dividing and do not begin diving again until stimulated to do so. Growth factors, nutrients, etc. are required to make these start dividing again. When these cells are needed, the appropriate growth factors will be introduced, and then they will begin dividing again. Some cells do continuously divide, such as epithelial (skin) cells. The cells that keep on dividing, even though they are not supposed to, are cancer cells. They eat up all your nutrients and form tumors etc.
What happens when cell do not respond to the signals that normally regulate their growth?
Cancer cells do not respond to the signals that regulate the growth of most cells. such cells called cancer cells divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues
What begins when cells in a part of the body start to grow out of control?
cancer.
What will happen if if the cell cycle becomes uncontrolled?
Uncontrolled cell cycle can lead to uncontrolled cell division and proliferation, potentially resulting in the formation of tumors and cancer. This can disrupt normal tissue function and spread to other parts of the body, leading to serious health consequences.
How are cancer cell growth differs from normal cell growth?
Cancer cell growth is uncontrolled, rapid, and does not respond to signals that typically regulate cell growth in normal cells. Normal cells have a regulated cell cycle with checks and balances to ensure controlled growth and division, whereas cancer cells have mutations that disrupt these regulatory mechanisms, allowing them to divide uncontrollably. Additionally, cancer cells can evade the body's immune system and can invade surrounding tissues or spread to distant organs, a process known as metastasis.
How do cells start cancer?
They become abnomal through gene theory or foreign saturation.
How are cells different from normal cells?
They're different because they grow faster than normal cells and start to kill the cells around them, which can result in a tumor and cause cancer.
Where are cancer cells found in the body?
Cancer cells are found in the affected organ or tissue. There are several types of cancer depending on anatomical location within the body like skin cancer, blood cancer, lung cancer etc. Also it depends on how a particular type of cancer spreads like the Carcinomas spread through lymph so the cancer cells can be found at lymph nodes whereas, the sarcomas spread through blood. Another noteworthy thing is that in the later stages of cancer it can spread to a distant organ and start a secondary cancer in the new location.
