Cancer cells divide excessively and invade other tissues. They do not have density dependence or anchorage dependence. Simply put, regular cells grow in an even layer while cancer cells grow tightly and on top of each other - an unnatural mass.
because the bodies immune system does not recognise they are cancerous cells, or because the body has no immune system Cancer cells are normal cells, with a defect, it's like if a baker makes cakes that no one likes but he still gets paid for it he will carry on making horrible cakes.
Cancer cells are characterized by their ability to divide more frequently and uncontrollably compared to normal cells. It's this nature of cancer cells that allows them to grow to large tumors seemingly uncontrollably. Also, cancer cells not only divide more frequently, they are also immortal, meaning that they can divide indefinitely while normal cells senesce (grow old and does not divide) after 60 or 70 divisions.
cancer cells grows uncontrolled and divide infinitely.
In humans, this cellular behavior is called "cancer"
Cells divide.
Cells in our body grow, divide, and die in a certain way. Cancer happens when cells either grow, divide, or die wrong or in the wrong way. It ends up being an unpredictable manner that causes uncontrolled growth and division.
Cancer cells divide and grow uncontrollably, forming malignant tumors. Although cancer cells can be quite common in a person they are only malignant when the other cells (particularly natural killer cells) fail to recognize and/or destroy them.
a. cancer cells divide uncontrollably. b. normal cells cannot make copies of DNA. c. cancer cells cannot make copies of DNA. d. normal cells divide uncontrollably. (A) cancer cells divide uncontrollably
Cancer cells divide quickly and almost indefinitely. This makes them easy to grow in a dish while tissue culture with healthy cells is almost impossible.
In multi-cellular organisms as cells grow and divide, they specialize.
Cancer cells lack the gene that stops cell growth at a certain point which causes them to grow and grow and not stop. Therefore, in cell growth, a cancer cell has nothing to tell it to stop growing.
If cells do not divide properly, then many problems can occur, cancer cells for example.
Their Growth Rate. It's the high school bookworm again! :D
No. HIV is a virus which invades from outside the body. Cancer is one's own cells inside the body which grow uncontrollably.
Bladder cancer will force normal cells to divide uncontrollably.
