“Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected” (What Is Cancer? What Causes Cancer?,1). Most cancers harm the body when cells begin to divide and form lumps of tissue called tumors. However, leukemia affects cells in the blood stream. While some tumors can grow to affect many different systems in the body, some are not dangerous and are referred to as benign tumors. There are many types of cancer, some more dangerous than others. Those among the most frequently diagnosed include breast cancer, ovarian cancer, renal cancer, colon and rectal cancer, and lung cancer.
Breast cancer is characterized by a malignant, or cancerous, tumor that develops in the cells of the breast. In most cases of breast cancer, the cancer begins in the cells of the milk producing ducts. If these cancerous cells make their way to other uninfected breast tissue, they can travel to the lymph nodes under the arms. Once inside the lymph nodes, the cancer has a way to spread to other parts of the body. The stages of breast cancer are determined by how far the cancer cells have spread beyond the original tumor. Many women diagnosed with breast cancer report that the first sign is a lump of tissue felt on the breast. Even so, most women brush off such lumps and do not get tested in time. Other symptoms of this type of cancer include swelling of all or part of the breast, skin irritation, breast pain, or a lump in the underarm area. It is possible, though, that some of these symptoms could signal something less serious like a cyst. “About 1 in 8 U.S. women (just under 12%) will develop invasive breast cancer over the cou...

Symptoms women often start noticing that indicate the possibility of having a cancerous tumor in the breast include a lump on the underarm or armpit, thickening of the nipple, fluid (not milk) leaking from the nipple, change in the size of the nipple or breast, changes of color, shape or texture of the nipple or the areola, and unusual pain in the breast or in the armpit (Stephan., 2010). These are the symptoms women usually start noticing before go to the doctor to ge...
Leukemia is another type of cancer it is a malignant progressive disease. Some symptoms of leukemia is people weight loss, frequent infections, and easy bleeding or bruising. Also chills, dizziness, fatigue, fever, nausea, night sweats, weakness, or sweating are also side effect or symptoms of leukemia. Most people have to shave their hair of and some people fight the cancer and win. Leukemia involves abnormal white blood cells these cells responsible for fighting infection. The abnormal cell in leukemia does not function in the same way as normal white blood cells do. The leukemia cells continue to grow and divide, eventually crowding out the normal blood cells. There is over 50,000 cases of leukemia occur yearly in the U.S.
What is Leukemia? Leukemia is a cancer in blood forming cells that are in early stages of development. Most of the time the white blood cells, but some types of leukemia start in other types of blood cells. Blood cells are form in bone marrow. Any of these cells can turn into a leukemia cell, once this happens the cell does not mature like it should. The cell may start to produce rapidly and the mutated cells probably won’t go through apoptosis like they should. These cells build up in the bone marrow and crowd out the healthy cells. Typically, leukemia cells get into the blood stream rather quickly. From the blood stream they can spread to places like lymph nodes, spleen, liver, central nervous system or other organs where the leukemia cells can cause those other cells to function irregularly.
The emphasis on health and fitness has become paramount in our society today in an effort to prevent and combat diseases such as Cancers. Cancers are a group of over 100 diseases that affects every aspect of the human system from skin, to bones, to muscles, to blood. One of the most common blood disorders is Leukemia. As defined by the U.S. National Library of Medicine, Leukemia is a type of blood cancer that begins in the bone marrow. The bone marrow is the soft tissue in the center of the bone that is responsible for the production of blood cells. The term leukemia means white blood. The term leukocytes refer to white blood cells, which are body’s defense against infections and other foreign substances. When Leukemia occurs there is an uncontrolled increase in the number of white blood cells. When this occurs, these cancerous cells inhibit the production of healthy red blood cells, platelets, and mature white blood cells. Over time the cancerous cells can spread to the bloodstream and lymph nodes. They can also travel to the Central Nervous System and the rest of the body.
Breast cancer is a type of cancer where cells in the breast divide and grow without normal control. By the time a lump is big enough to feel, it may have been growing for at least ten years, and by that time, it is harder to control how fast the cancer will grow or spread to other parts of the breast, and maybe even other parts of the body.
According to the American Cancer Society, Each year, more than 200,000 women are diagnosed with breast cancer; furthermore Twelve percent of all women will contract the disease, and 3.5% of them will die from breast cancer (American Cancer Society, 2005). There are risk factors that may lead to breast cancer. There are 4 stages of breast cancer and several treatments, although treatments vary from types and stages of breast cancer. Breast cancer is the leading cause of death among women who are 40 to 55 years old (Breast Cancer, 2009).Cancer occurs when cells divide uncontrollably. It changes from a normal cell to cancerous cells that require gene alterations. Therefore the altered genes and the uncontrolled growth may lead to tumors. Tumors can be benign or malignant, benign tumors are not cancerous whereas malignant are cancerous. Benign tumors will not spread, but it can damage the tissues around it. Malignant tumors invade, damage, and destroy tissues that are nearby and can spread. When cancer cells break away from a malignant tumor and enter into the bloodstream, cancer can spread throughout the body. The cancer cells from breast cancer can be found in the lymph nodes under the arm. Cancer that spreads into other parts of the body; its still has the same name as the original cancer. So basically if you are diagnosed with breast cancer and it goes into your lungs, you still have breast cancer.
Of the few people that know what breast cancer is some of them just believe that it is a lump. They do not know that there is a process to breast cancer they do not know that the tumor comes from somewhere and does not magically appear. Breast cancer can happen a few different ways in the breast, but “the most common type of breast cancer is ductal carcinoma” (cancer.gov). This type of breast cancer begins in the lining of the milk ducts. The ducts are the tubes that carry the milk from the lobules to the nipple. Think of them as little veins running from the nipple to a little pouch. Another place that the cancer could start is...
Breast cancer is a malignant tumor that starts in the cells of the breast, usually starts in the inside the milk ducts or lobules. A malignant tumor is a cancer cells that can grow into in tissues or spread to different parts of the body. Doctors say one in eight women will be diagnosed with breast cancer in their lifetime. Breast cancer is the mostly diagnosed in women, and the second leading cause of death for them. Even though breast cancers are mostly found in women men can get it to but it’s very rare.
Cancer can affect anywhere from the brain, lungs, and liver, to the breasts and heart. One of the most common types of cancer is “Carcinoma” “Cancer that begins in the skin or in tissues that line or cover internal organs -- "skin, lung, colon, pancreatic, ovarian cancers," (Medicine net)”. This shows that dozens of different types of cancer only fall into a small category and can all only be treated by certain means. Some types of cancers are even incurable making them particularly dangerous because once you get one of those types of cancers there is nothing that you can do except wait for the inevitable death that awaits you. Meanwhile other forms of cancers are minor, meaning that there is therapy and cures for them, however just because they are minor compared to the more deadly types of cancer, all forms of cancer are extremely potent and dangerous. Sarcoma is another form of cancer “that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue -- bone, soft tissue cancers, (Medicine Net)”. This form of cancer affects the body by taking out the supportive tissues and functions, causing extreme pain and discomfort for whom ever is unlucky enough to get it. One of the most common types of cancer is leukemia which “Cancer that starts in blood-forming tissue such as the bone marrow and
Cancer is a type of disease that has many variations. it is an extremely broad disease, consisting of over 200 different types. It affects millions of people around the world each year. The disease occurs because of an irregular cell growth in the body. The cells uncontrollably divide and grow through the process of mitosis. This creates either benign, or malignant tumors. Benign tumors are not dangerous, but malignant tumors are dangerous and are given the term ‘cancerous’. The malignant tumors can invade other parts of the body by traveling through either the bloodstream, or the lymphatic system. It is a very dangerous disease, it is not contagious, and it can be cured if it is diagnosed and treated early. Many cancers have a different mortality rate, but not all of the different types of cancers have a high mortality rate.
Leukemia is a cancer of the white blood cells. It begins in the bone marrow, the soft tissue inside the bones. Within the bone marrow is where white blood cells are created, that help fight off bacteria, viruses, and other microorganisms within the body that cause infections. The disease develops to when the white blood cells are being produced out of control. The cells that are being produced do not work properly as they should, they grow faster than a normal cell would and don’t know when to stop growing. Overtime, if not treated properly, the white blood cells will over crowd blood cells, creating a serious problem such as anemia, bleeding and infection. Leukemia cells can spread to the lymph nodes and other organs in the body causing swelling and pain.
Breast cancer is a malignant growth of tissue (tumor) in the breast. Unlike noncancerous (benign) tumors, malignant tumors are cancerous and can spread to other parts of the body. The most common type of female breast cancer begins in the milk ducts (ductal carcinoma). Breast cancer is one of the most common types of cancer in women.
Breast cancer is cancer that develops from breast tissue. The signs of breast cancer might include a change in the breast size, dimpling of the skin on your body, a lump in the breast, fluid coming from the breast nipple, or ever red patchy skin around the breast. When the breast cancer spreading, there might be swollen lymph nodes, shortness of breath, yellow skin or bone aches. Women in the U.S. have a 1 in 8 chance of evolving an aggressive form of breast cancer during their lifetime. When breast cancer is aggressive, it starts in the breast glands but grows into breast tissue. There are many treatments of breast cancer, there is no cure found yet. However they are effective treatments out there to handle breast cancer patients. Breast cancer treatments will depend on what type of breast cancer you have developed, also where your cancer has spread. The breast cancer patient would work with their doctor to come up with a plan that 's best for them to improve their health. There is two types of aggressive cancer, one is the ductal carcinoma. This is the most type of cancer a lot of breast cancer patients have, making up about 80%. Cancer cells start in a milk canal, break through the walls, and invade breast tissue. It can continue constrained, which mean that it stays around where the tumor was first started. On the other hand cancer cells may spread anywhere in the body. Invasive lobular carcinoma is about 10% of aggressive breast cancers. Dealing with ILC most women feel a thickening around or in their breast instead of a lump in their breast. Sadly some women might have signs of the combination of both. These are most asked questions with dealing with aggressive cancer. Like what upsurges the...
Cancer cells differ from normal cells in size, structure, function, and growth rate. These malignant cells lack the normal controls of growth seen in healthy cells, and grow uncontrollably. This uncontrolled growth allows the cancer cells to invade adjacent structures and then destroy surrounding tissues and organs. Malignant cells may also metastasize to other areas of the body through the cardiovascular or lymphatic systems. This uncontrolled growth and spread of cancer cells can eventually interfere with one or more of a person's vital organs or functions and possibly lead to death. The primary sites of cancer metastasis are the bone, the lymph nodes, the liver, the lungs, and the brain (McCance & Roberts, 1998).
Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
