Cancer causes the normal cells of the body to grow and divide uncontrollably. Eventually these cancerous cells will become tumors or growths and may spread to other parts of the body.
The process starts when a cell undergoes transformation. Usually body would recognize such a cell and destroy it, however if it is not destroyed it forms a tumor. A benign tumor is not dangerous whereas malignant tumors impact the function of different organs thus are more dangerous, described as Cancer. There are many abnormalities which might cause the malignant tumor invasion.
- excessive proliferation
- unusual number of chromosomes
- changes in the cell surface cause detachment from neighbouring cells thus contribute to spreading throughout the body.
- might secrete signal molecules which cause the vascular growth more close to the cancerous site.
Such abnormalities occur due to a fail in the system of cell division and DNA replication.
A healthy cells DNA begins to change during the multiplication process. This is where the genetic cold alters and healthy breakdown which allows the cancer cells to increase.
Cancer happens when mitosis, I'll put this quite simply, goes crazy.
Mitosis begins happening at a rapid rate and will not stop. Even the phases are shortened.

In the cell cycle of cancer cells interphase is still the longest phase. However, interphase is shorter in cancer cells than in normal cells.
The overproduction of cells causes cancer since there is no cell growth regulation. This causes masses to grow uncontrollably and become cancer.
Nk (natural killer) cells.
what type of cancer is uncontrolled and invasive
They can be mutated through irradiation.
dd
Yes
Bladder cancer will force normal cells to divide uncontrollably.
One could argue that all body cells can potentially become cancerous and therefore they are all dormant cancer cells. But by that definition, a dormant cancer cell is just a normal, healthy cell.

No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
Cancer is caused when the normal mechanisms that control cell growth become disturbed, causing the cells to continually grow without stopping.
because the cancer's cell eat the other normal cells. So that make the patient's organ become larger and larger, because the cell grow up uncontrolled
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.
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.
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.
