What is the difference between cancer cells and normal cells?
Normal cells in the body grow and divide in the way in which they should. New cells are produced only when they are needed. Cancer cells grow uncontrolled and have nothing to do with the needs of the body. A mass of tissue that forms when cells grow and are not needed, then they form what is called a tumor. There can be two different kinds of tumors in the body – benign and malignant. Benign tumors are non-cancerous and malignant tumors are cancerous.
Cancer cells are damaged normal cells. They could continue growing until they endanger healthy cells and organs of the body. They have a different growth pattern than normal cells and tend to multiply in the wrong way. Thus they can spread over a very large area and do not have the immunity that normal cells do.
While normal cells are similar in structure to cancer cells, the number of them in more balanced with the needs of the body and the activity level of the individual. They perform a purpose in the body. They have a blood supply system. They contribute to the body’s immune system and empower the body to be healthy.
There are three different classifications of cancer cells, which are expressed in grade levels.
Grade 1 cancer cells
These cells do not look any different from normal cells. They grow slowly and give little symptoms that they are cancerous. When cancer is discovered at this point it is said to be in the early stage and is curable.
Grade 2 cancer cells
At this point there is a difference in the appearance and growth of the cancer cells from normal cells. Although they are still growing, they are growing at a faster than normal rate. The cancer is still curable at this stage if the proper treatment is given. There is also the possibility that the cancer is incurable because a complete cure can only be found for Grade 1 cancers.
Grade 3 cancer cells
These cells are in the final stage of growth and are out of control. The patient is usually in a lot of pain, especially in the area of the body where the cancer cells are most numerous.
What happens when cell growth gets out of control?
The tumors that result in parts of the body from uncontrolled cell growth are classified as one of two types of growths – benign and malignant.
Sometimes cells start to grow without regard for the normal balance between cell death and the need for new cells. The growth that develops is small and harmless and is therefore called a benign tumor. It can develop in any part of the body, but it is not cancerous because it doesn’t invade or damage any other part of the body. They can be removed without risk and they are never fatal.
Cells grow and divide regardless of the body’s needs and keep growing. They are very aggressive and the resulting growths are called malignant tumors. They are cancerous and they invade the other cells of the body so that they can spread rapidly. They can even break away and enter the blood stream, which gives them access to all parts of the body and result in new tumors.
Some forms of cancer are curable and others are not. However, in the majority of cases where the cancer cells are discovered in the early stages, the outcome is positive.
