The regular cells that naturally replace themselves get mutated. Those mutated cells keep splitting and replacing dead cells at the normal rate, which is very fast. In a few seconds, 10 million cells die and are replaced. Because of this, cancer cells can spread quickly.
so hair cells divide really fast too. That's why when treating cancer (rapidly dividing cells) you may lose your hair. Because the treatment like radiation or chemo kills all rapidly dividing cells
Cancer cells don't need much more blood than any other cell - the problem is when there is a collection of cancer cells in a tumor. The tumor as a whole is rapidly dividing (usually), so it needs a great deal of energy and nutrients to do that. Nutrients are brought into the body's tissues by circulating blood, which is why many tumors develop angiogenesis properties (the ability to create new blood vessels).
Yes they are, because they have a lower resistance upon germs (germs in the sense: things that does not belong to your body, not particularly bacteria, so also radiation), so radiation and drugs have a easier time coming in them than in other cells.
Cancer is a strange disease in that it is the body's own cells doing the damage. Normal cells have what is known as cell growth inhibition. This means the cells don't overcrowd each other and the cells are able to perform their function. Cancer is basically cells that don't have this growth inhibition. In fact, the cell is programmed so that all it desires to do is reproduce. As the cells grow rapidly, they form a tumor. This tumor does not do the function a normal cell would do, but instead takes nutrients and oxygen from the blood and use this to do nothing but reproduce. As the tumor grows, it overcrowds the normal cells and inhibits them from properly doing their job. For instance if a tumor is growing in the lungs, it can prevent the normal cells around them from intaking oxygen and exporting carbon dioxide. This eventually leads to organ failure. Not only can this be damaging to the organ the cancer cell started in, but if cancer cells enter the lymph system or blood stream, they travel to other body sites and begin a new tumor. This can lead to multi-organ failure, and eventually death. Fortunately there are many ways we can prevent cancer, such as not smoking, exercising, eating a proper diet, and receiving anual check ups from a doctor.
In cancer cells, interphase is not the longest part of the cell cycle. This is because cancer cells can progress rapidly through the cell cycle, spending less time in interphase compared to normal cells.

Well. Cancer is basically cells that rapidly grow and crowd out useful cells. It all depends where the cancer is. If it's a tumor, it can be anywhere in the body. So if one has a tumor in the leg, it is a bunch of cells that rapidly produce that can prevent useful cells from doing their duty. Another type of cancer is leukemia, blood cancer. Nothing gets mutated, but white blood cells are rapidly produced, crowding out the red blood cells and platelets. I hope this helps.
The body's cells love glucose, so they do feed off sugar. Cancer cells breed more rapidly, which means they eat more.
It depends on the way you use it, as well. In most cases, the hallucinations that one receives from the use of marijuana are caused by brain cells dying. Brain cells do not reproduce rapidly, so this does have a long-term effect if done consistently. If smoked, marijuana has the potential to cause lung cancer, although that potential is far less than that of cigarettes.
Cancer is a disease caused by severe disruption of the mechanisms that normally control the cell cycle. This disruption leads to uncontrolled cell division, which if unchecked can result to death.
This is typically cancer. A disease like this would mess with the way cells reproduce so that replicated cells would come out wrong
Chemotherapy is used to fight the cancer cells, but in the process it can also be harmful to other cells in your body that these drugs mistake for cancer cells. The way chemotherapy works is that it targets whatever cells are rapidly dividing. For this reason, the cells in your body that make hair grow so fast get harmed along with the cancer cells. Fortunately, the cells that produce your hair ca eventually go back to normal and your hair growth will resume again.
Cancer cells are already cancer, it is redundant for a cancer cell to get cancer, however, it is true that cancer cells can die, for various reasons. The reason why cancer is so dangerous to the body is that cancer receives all the same support that healthy cells receive, and is not attacked by the immune system. The body takes care of its own cells; the blood supplies all the needs of cellular metabolism. That makes it easy for cells to survive. So even though cancer cells are abnormal and dysfunctional, they can usually survive because it is easy for them to do so.
because it can decompose quickly and reproduce quickly

Cancer is a cell mutation where the cell reproduces rapidly and too much. Then those new cells become cancer cells and continue to split out of control. Yet, the body does not need so many of one type of cell so quickly. The cancer cells are large in quantity and take over that area, causing pressure on other normal healthy cells. Those tissues are overthrown by the cancer ones and it off-sets the balance of the body. This is dangerous because you need a specific amount of everything in your body to work, so you have many cancer cells and less of the healthy cells and can be very hazardous to countless of daily functions necessary to life. There really is only one Cancer, and that's just cancer, no matter where it is in your body. It just affects different cells. i.e.- Lung cancer is a mutation in lung cells, and Brain cancer is a mutation in brain cells. The only two categories cancer is divided into generally are malignant and benign. Malignant cancer will carry the cancerous cells by the bloodstream to other parts of the body, and the cancer will then affect that spot as well. This cancer is slightly more dangerous than benign cancer, which will only stay in the organ where it first started and will not travel through the body.
