Cell Growth and Diffusing in the Body

A while back, around 1951, a woman named Henrietta Lacks was brought into the hospital and was diagnosed with cervical cancer, and in this diagnosis, doctors took samples of her cells, in which they discovered a special cell, called HeLa cells. They seemed to reproduce, and continue to grow even after Henrietta Lacks has passed away. It is known that cells reproduce through the process of mitosis, and this forms a great amount of cells. what has been hypothesized is that there must have been a mutation in her DNA which caused the formation of these HeLa cells,and when these cells reproduced, many HeLa cells had formed in Henrietta Lacks' body. The HeLa cells may have also been the reason behind her cervical cancer, and internal bleeding. However, what may be the most accurate assumption of HeLa cells, and other cancer formation is because of mutations in a humans DNA, and when cells form, they have to reproduce, and they do not seem to have a cell cycle control system, which the cycle operates set of molecules in the cell that both triggers and coordinates key events in the cell cycle, and without this cycle, the cells do not have control over their reproduction, and this can form into cancer. Many researchers have found that cyclin dependent kinases work as a signaling protein to let a cell know when to divide or not, they attach at checkpoints which work as a regulator. Cdk's function by phosphorylating substrate proteins that tell the cell what to do, whether that is to stop dividing or to continue with the cycle. Due to the fact cdk's are a controlling factor that determine whether the cell continues or stops dividing it is evident that there is a problem in cancer cells that ignores or has a much more rapid rate of cyclin/ cdk's produced that signal for the cell to continue dividing making the cell cycle control system void.
