Dividing normal human cells are called somatic cells. These cells undergo the process of mitosis to divide and create identical daughter cells with the same genetic material.
the cancerous cells
Cancerous cells grow uncontrollably and can invade nearby tissues, while normal cells grow and divide in a regulated manner. Cancer cells can also spread to other parts of the body, a process called metastasis, which normal cells do not do. Additionally, cancer cells can evade the body's immune system and resist cell death signals, unlike normal cells.
Malignant lymphocytes multiply uncontrollably and do not perform their normal functions.
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
Non-cancerous cells that do not affect health are referred to as normal cells. These cells function properly within the body and perform their intended roles without causing harm or disrupting the normal functioning of tissues and organs.
The process of a protein unfolding is called denaturation. During denaturation normal alpha-helix and beta sheets are disrupted causing the protein to uncoil and become misshaped
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.
