Cancer is when abnormal cells divide in an uncontrolled way and develops when the body’s normal control mechanism stops working. Cancer cells are different than normal cells in many ways that allow them to develop out of control and become invasive. Normal cells mature into distinct cell types with particular functions and cancer cells do not. Unlike normal cells, cancer cells continue to divide without stopping. Many cancers form solid tumors, which are masses of tissue. Tumors can be malignant or benign. Unlike malignant tumors, benign tumors do not invade tissues that are near. Cancerous tumors are malignant, which means these tumors invade tissues. A cancer that has spread from where it started to other places in the body is called metastatic cancer. The process is called metastasis. Treatment may help prolong the lives of some people with metastatic cancer.
Malignant tumor or malignantneoplasm, also known as cancer, is a disease caused by abnormal cell growth. The cell is potential to spread to other parts of the body. But not all tumors are cancerous such as benign tumors. They do not invade to other parts of the body. Some people may have symptoms such as abnormal bleeding, a prolonged cough, a new lump, unexplained weight loss, and a change in bowel movements among others. But those symptoms do not only indicate cancer, they can also occur because of other issues. Actually, there are over 100 different known cancers that affect humans.
By definition, a cancer is a disease that is characterized by “controlled growth and spread of abnormal cells,” (Laini, online). According to Laino, cancer forms when there is a growth of abnormal cells. The abnormal cells also known as the cancer cells grow and forms a tumor in which will began to attack nearby body tissues and organs. Depending upon the various types of cancer, the cancer cells attacks different tissues and organs. As the tumor spreads, some
Cancer is caused by a malignant growth or tumour as a direct result on the uncontrolled division of abnormal cells in any part of the body. There are more than 100 different types of cancer, which each type of cancer being named after the organ of its origin. Normal cells divide uncontrollably into hyperplasia, then again into dysplasia before finally turning into cancer, although at the hyperplasia and dysplasia stage,
if a cell grows too large it cannot carry out these process efficiently. Cancer is when the cell process mitosis is uncontrolled, which means they grow too fast. they grow faster than normal cells, they can break away from groups of cells and travel to other places in the body. Cancer cells spend less time in Interphase therefore they are dividing more. When cancer cells are born there are two types of tumors that can be created in the human body. Benign Tumor: Benign Tumors have cells that do not migrate to any other parts of the body and do not harm other parts of the body. this tumor not that much of a significant threat to the human body. In all of these tumors cancer is cancer. When you find out that you have cancer you must get medical attention A.S.A.P. There can be things done to slower and stop cancer in the body. There is chemotherapy or surgery to remove the Tumors. Malignant Tumor These tumors have cells that can migrate to other parts of the body, potentially causing the cancer cells to spread to the body. therefor this tumor is very dangerous which can cause very serious harm to the
“Cancer”, its a disease that have claimed the lives of millions, its a disease that has not been cured, and its a disease that have many different forms. There are many types of cancer. It can develop in almost any organ or tissue, such as colon, lung, skin, bones, breast or nerve tissue. Cancer is defined as “a malignant growth or tumor resulting from the division of abnormal cells.” Some of the body cells begin to divide without stopping and spreading into surrounding issues. As cells become abnormal, old and damaged cells survive somehow when they should die, and the new cells form when they are not needed. Cancers of the blood, such as leukemias generally do not form solid tumors. These cells can divide without stopping and may form growths called tumors.
Cancer cells are cells that disregard some needs and limitations of the body. Cells like this are also called malignant cells. However, they can also reproduce. This is when the problem comes in. Daughter cells that are produced by the previous generation of cancer cells are also cancer cells. As time passes, these cancer cells will gather together in clumps and spread into the other parts of the body. These clumps are called metastases. If the cancer cells are not exterminated quickly enough, they can continue to increase in numbers and eventually destroy the part of the body where they are located.
These tumors cause damage to the healthy cells of the body and have the potential to invade some other body parts as well. These diseases causing tumors are known as malignant tumors. One other type of tumors known as benign tumors; these are not harmful since they do not cause harmful effects on the body. Therefore, cancer is associated with these malignant tumors that do cause damage to the human body. If the uncontrolled growth of cells is not stopped, death could occur as a result. There are a number of types of cancers that each has been classified depending upon the body part that was initially infected by the cancer cells. For example: lungs cancer, breast cancer, intestinal cancer, and so
Benign cell is used to describe both medical conditions tumors an usually refers to a process that's not especially dangerous. For instance uterine fibroid are common benign tumors. Benign is not cancerous, will not cause death. There are different types of benign tumors the most frequent tumor in women is perimenopausal. The benign tumor can be deadly if it grows in an enclosed space such as the skull, or in regions of the body where their presence can damage vital organs they can be dangerous.
The most important factors to classify tumors as benign or Malignant is its invasive potential1. First of all, Benign tumors lack the ability to invade adjacent tissues and are in a confined location typically encapsulated in a fibrous capsule2. Whereas, malignant tumors will often require chemotherapy and radiation, while benign tumors can be removed by surgery alone2. Third, benign tumors rarely recur after surgery, while malignant tumors are known to recur much more commonly2. In fact, surgery to remove benign tumors are much easier in contrast to malignant tumors2. Also, it is harder to remove malignant tumors because they attack and access nearby tissues, whereas it is easier to remove benign tumors for their clear fibrous boundaries2.
The two types of tumor cells are benign and malignant tumor cells. A benign tumor is a tumor that stays at its original site and can removed surgically or killed by radiation. However, a malignant tumor is one that is able to leave its original site and spread to other parts of the body through the bloodstream becoming cancerous. The benign tumor is much less harmful than the malignant tumor due to the fact that it can leave it original site in the body and infect other
Cancer can be defined as a state whereby the human cell goes trophoblastic. This is a process whereby the human cell tends to multiply uncontrollably. The affected part of the body has its cells grow, divide and multiply uncontrollably thereby forming a lump. Cancer affects the blood and organs that form blood thereby finding its way to the blood streams. It invades the nearby tissues and keeps spreading to all the parts of the body.
ImageCancer cells are the production of abnormal cell division. Our bodies have an order in which they replace worn-out cells because each of our cells have instructions that tell our bodies how fast the cells should grow and divide and when they should die. This balance between the division of cells and the death of cells keeps our bodies functioning properly. The difference between cancer cells and healthy cells is that when our cells start to develop without this balance between growth and death, small lumps of benign or harmless cells will form, it can occur anywhere on your body.
One of the deadliest diseases known man, cancer, is responsible for every one out of every four deaths in the United States. Worldwide, there are more than 10 million new cancer cases per year, and cancer is the cause of approximately 12% of all deaths (Silvera & Rohan, 2007). This count is rising and will continue to do so as scientists and researchers claim that there is no cure yet, just treatment. So, what exactly is cancer and how does it work? Cancer can arise virtually anyplace in the human body, which consists of trillions of cells. Generally, human cells mature and divide to create new cells as the body needs them. Whether it is from damage or aging, cells eventually die and new cells take their place. However, when cancer develops, this systematic process becomes disrupted. As cells become more and more abnormal, old or damaged cells live when they should die, and new cells form when they are not needed (Doll & Peto, 1981). These new cells are able to divide without stopping which can eventually lead to abnormal growths called tumors.
Tumors are one of the most feared diseases of our time. Many people upon hearing the word “tumor” immediately resonate to the conclusion of it being cancer, which is not necessarily true. Tumors fall into to two main types, benign and malignant. Although they are considerably different in tissue invasion, their nature that makes them distinct and symptoms, they are also quite similar in the way they recur in the same location, growth size and their health risks.
