The tumor cells are the cells that the body does not need but which exist due to abnormalities in the division process. Understanding how these cells appear is important if willing to understand cancer. When the natural process of cells growing and dividing goes wrong these cells are produced by the body even though they are not needed. To be more exact the cells in a body grow and divide in a controlled way but when they become old and damaged they normally die and are replaced by new cells. Mutations which affect the normal process of cells growing and dividing and then the old cells do not die as they should. However, new cells are still forming and they form a mass of tissue which is called a tumor.
If a patient has a tumor does not necessarily mean that he or she has cancer. There are different types of tumors, the benignant, malignant and pre-malignant. The benign tumors are non cancerous and can be removed without too many chances to appear again. They are tumors that do not spread to other organs or parts of the body. The malignant tumors are the concerning ones. These are the cancerous tumors formed by cancerous cells that will most likely invade surrounding tissues and spread to other organs or parts of the body. Spreading is called metastasis in medical terms. There are however types of cancer that do not form tumors, such as leukemia.
The tumor cell lines are cell cultures that are characteristic to a certain type of cancer. For example, DU145 and MCF-7 are tumor cell lines for prostate cancer and breast cancer. Specialists believe that the cell lines may be useful in research for new types of drugs and treatments for benign tumors. Cell lines in tumors are primarily used for screening studies that involve drug sensitivity or effectiveness of drugs that are being used to cure cancer. However, the studies are experimental and specialists believe that cell lines can provide information about the metastatic behavior of cancerous cells.
The brain tumor cell can also be cancerous or non-cancerous. Tumors in the brain are a result of the abnormal and uncontrolled cell division. A brain tumor is considered any intracranial tumor that has been created by the abnormal growth of cells of the brain tissue, nerves, envelops or tumors that have spread from other organs. They can affect any part of the brain and they are the leading cancer-related death cause in the United States which is also responsible for the death of patients younger than 35 years.
Knowing some basics things about the cancer cells is crucial for someone who wants to learn about cancer. observing the way tumor cells grow and divide can provide information about how to discover cancer at its incipient stages and how to cure it and specialists are doing research in this way but it studying is still a challenge for today’s medicine.
