Cancer Cells vs 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. If the cells are not needed for growth or replacement then a mass of tissue is formed, which is called a tumor. Two types of tumors are there, benign and malignant. Benign tumors are not cancerous but malignant tumors are cancerous.
Cancer cells are those cells which are normal cells but damaged. These damaged cells could grow immensely to damage other cells as well. Cancer cells differ from normal cells in different ways such as the growth will not be alike the normal cells (will less or more). The cancer cells tend to multiply incorrectly, cancer cells tend to spread to a wide area. It won’t have the immunity power of normal cells.
Normal cells while similar to cancer cells, the amount of them are more in balance to produce a more normal level of activity. These are useful cells that have a built-in blood vessel system and produce immunity and empower human body.
The cancer can be classified into three different grades.
Grade 1 is when cancer cells look alike like normal cells. In other words these are a slow growing cell which doesn’t show much symptoms of a cancer infection. A cancer infection if identified in this stage can be cured. This is also termed as early stage.
Grade2 is when cancer cells starts to appear different from normal cells. These are fast growing cells and are in the growing stage. If proper treatment is given at this stage, the disease can be cured. A cancer if unidentified in grade 2 could be termed as a stage where hope of curing is less or rare. A complete cure if guaranteed is only during the initial stages.
Grade3 is when cancer cells are found to be immensely growing and is in the final stages of growth. This is when, the patient feels the pain in the parts of the body where cancer cell are grown. The pain will be severe and uncontrollable.
There are different types of cancers and is differentiated according to which part of the body cancer is being infected. Some to be termed are cancer in a gland (adenocarcinoma), cancer found in muscle cells (leiomyosarcoma), Cancer found in nerve cells (neurosarcoma), cancer in fat cells (liposarcoma) etc.
What happens when cell grows out of control?
Cell growth can be classified into benign and malignant growth.
Benign- at times cells starts to grow without balancing the normal growth between cell death and growth and a small and harmless lump of cells are formed this is called Benign tumor. This tumor can grow in any part of the human body; it could be intestine, the prostate or even the skin.
Benign tumors are not cancerous. They do not invade nearby tissues nor spread to other parts of the body. They can be removed and are not a threat to life.
Malignant –Unlike normal cells, when a cell grows and divides itself regardless of the needs and limitations of one’s body, it grows in abundant. These cells with such aggressive behaviors are called malignant cells and the excess growth is called malignant tumor.
Malignant tumors are cancerous. They can grow in different parts of the body and eventually overwhelm and destroy that part or the organs of the body. They invade and damage nearby tissues and organs, and they can break away and enter the blood stream to form new tumors in other parts of the body.
Cancer is not a disease that can be hundred percent curable. However 80 percent of the cases, if identified during the initial stages, are curable. The most important thing to be kept in mind is that if the cancer is diagnosed at early stages and timely health care is given it can be cured.
