Cancer cells normally have a defect in their receptor proteins on the membrane. There are several growth receptors on the surface of cells, and if one of them is faulty, cancer may form. The cancerous mass will continue to divide if there is no negative feedback from the cells surrounding it. In addtition to not being able to receive normal signals that regulate the cell cycle, cancer cells do not stop dividing when growth factors are depleted, simply put cancer cells don't require nutrients to grow, however they may still receive nutrients. As long as a cancer cell is provided with nutrients they may grow indefinately until some random point in the cycle where they may stop, rather then stopping at checkpoints in the normal cell cycle, making them somewhat "immortal". These are the most common differences in cancer cells and normal cells.

What is one main difference between a normol cell and cancer cell?
One main difference between a normal cell and a cancer cell is the ability of cancer cells to divide and proliferate rapidly and uncontrollably. Unlike normal cells, which have mechanisms in place to regulate cell division and prevent excessive growth, cancer cells bypass these controls and continue to grow and divide, leading to the formation of tumors.
What is the difference between invasion of cancer cells and metastasis of cancer cells?
Metastasis is a migration of Cancer whereas invasion is when the cancer growth goes into new part.
What is the difference between cancer cells and old cells?
cancer cell are cells that have a problem in their DNA which can lead to out of control division and old cells have no problems with their DNA they just die and cause no damage
Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
How is the behaviour of cancer cells different from that normal cells?
Normal cells divide in an orderly way to produce more cells only when the body needs them, whereas cancer cells continue to be created without control or order.
One difference between a cancer cell and a normal cell is that?
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

What are the chemicals or elements that make up a cancer cell?
Cancer cells are made of the same chemicals and elements that normal cells are made of. The only difference is a mutation in the DNA.
What does bladder cancer do to the normal cells?
Bladder cancer will force normal cells to divide uncontrollably.
Difference between cancer cells and cells of the spinal cord?
Spinal cord cells can never reproduce if they're damaged while cancer cells replicate incredibly fast.
What is the difference between cancer cells and old cells?
cancer cell are cells that have a problem in their DNA which can lead to out of control division and old cells have no problems with their DNA they just die and cause no damage
What is the difference between normal and abnormal red blood cells?

Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
How are cancer cells different from normal cells in the lung tissue?
Cancer cells and normal cells in lung tissue differ in several key aspects, primarily due to genetic mutations and alterations in cellular behavior that drive the development and progression of cancer. Here are some of the fundamental differences between cancer cells and normal lung cells: Uncontrolled Growth and Division: Cancer Cells: Cancer cells have lost the normal regulatory mechanisms that control cell growth and division. They divide and replicate at an abnormally rapid rate, leading to the formation of tumors. Normal Cells: Normal lung cells follow a controlled and regulated process of growth and division, ensuring that new cells are produced only when needed. Genetic Mutations: Cancer Cells: Cancer cells often harbor genetic mutations or alterations in their DNA. These mutations can activate oncogenes (genes that promote cell growth) and inhibit tumor suppressor genes (genes that regulate cell division and prevent tumor formation). Normal Cells: Normal lung cells have intact and functional DNA that maintains the proper balance between cell growth and cell death. Loss of Apoptosis: Cancer Cells: Cancer cells can evade apoptosis, which is a programmed cell death mechanism that eliminates damaged or abnormal cells. This allows cancer cells to survive and accumulate, contributing to tumor growth. Normal Cells: Normal lung cells undergo apoptosis when they are damaged or no longer needed, ensuring proper tissue maintenance and homeostasis. Invasion and Metastasis: Cancer Cells: Cancer cells can invade surrounding tissues and spread to distant parts of the body through the bloodstream or lymphatic system, a process known as metastasis. Normal Cells: Normal lung cells remain localized to their specific tissue and do not invade neighboring tissues or spread to other parts of the body. Angiogenesis: Cancer Cells: Cancer cells can stimulate the formation of new blood vessels (angiogenesis) to supply the growing tumor with nutrients and oxygen. Normal Cells: Normal lung cells do not induce excessive angiogenesis unless needed for tissue repair or growth. Cell Shape and Organization: Cancer Cells: Cancer cells often have irregular shapes, sizes, and organization. They may form disorganized clusters within tumors. Normal Cells: Normal lung cells have a specific and organized structure, contributing to the proper functioning of lung tissue. Functionality: Cancer Cells: Cancer cells do not perform the specialized functions of normal lung cells. Instead, they divert resources toward rapid proliferation. Normal Cells: Normal lung cells carry out their specialized functions, such as gas exchange and mucus production, to maintain respiratory health. These differences collectively contribute to the aggressive and destructive behavior of cancer cells compared to normal cells in lung tissue. Understanding these distinctions is crucial for developing targeted therapies that selectively target cancer cells while preserving the health and function of normal cells.
Describe how cancer cells differ from normal cells both structurally and in cell activity?
Cancer cells differ from normal cells structurally as they look majorly clumped with unusual patterns or formations. Cancer cells differ in cell activity compared to normal cells greatly as they are constantly growing and dividing while normal cells do not and stop growing and dividing when touching another cell.
What is the relationship between DNA and cancer?
The relationship between Cancer and DNA cancer begins when mutations distrupt the normal cell cycle, causing cells to divide in an uncontrolled way.
