"I know people are pretty well embarrassed just at the mention of colon cancer. Sticking a tube in you to find out what's wrong is not a nice thing. But I can tell them, a 30- or 40-minute test is worth it. We have to make them feel more comfortable about getting screened." said Eric Davis. Colon cancer is a hereditary gene that can be passed down from one generation to the next. People need to become more aware of this disease to stay healthy. Cancer in general is a horrible disease that people aware effected with everyday. Some ways to understand colon cancer a little bit better is by its causes, symptoms, diagnosis, prognosis, treatment, prevention, and how it has to deal with genetics. There are many different causes to colon cancer that people need to be aware of. In the large intestine there are polyps. There are several different types of polyps. There is adenomas, which have a high chance of having …show more content…
This will help the type of treatment to use, because they will know what stage the person is in. The method doctors normally use is the TNM system. T stands for the tumor and how big it is and what it looks like. N stands for the lymph nodes, because they determine the ratio of the spreading of the cancer. M stands for metastasized, which helps them see if the cancer has gone into other organs. They number the letters by how much the one stage has occurred. Colon cancer has four stages, which are from the TNM system. Stage one of the cancer is Tis, N0, M0. The T says that the tumor has not gotten very big and the N and M say zero because those processes have not happened yet. Stage four, which is the farthest stage, is Any T, Any N, M1. The T and N could be any type of those occupancies since they are so far into their processes and M means that that process has occurred. The prognosis for colon cancer is extremely important so the person can get the correct treatment to become healthy
Pancreatic cancer has become a taboo topic that many people are afraid to speak out about. It looms over families like a dark cloud, and manages to destroy people in a scarily short amount of time.
Colorectal cancers are thought to develop slowly over a period of several years. Before a true cancer develops, there usually are precancerous changes in the lining of the colon or rectum. These changes might be dysplasia or adenomatous polyps. A polyp is a growth of tissue into the center of the colon or rectum. Some types of polyps (hyperplastic polyps and inflammatory polyps) are not precancerous. However, having adenomatous polyps, also known as adenomas, does increase a person’s risk of developing cancer, especially if there are many polyps or they are large.
Colon cancer is the third most common cancer in men and women, responsible for more than 57,000 deaths in 2001 alone. Colon polyps, which can lead to colon cancer, are found in about 30-40% of people aged 60 or older- and the risks of polyps increase with age” (Lerche Davis, 2003). Most cases of colon cancer start as small adenomatous polyps. Many people experience no signs or symptoms in the early stages of colon cancer. Some signs and symptoms can include diarrhea, constipation, or any change in consistency of your stool that continues for longer than a month. Any bleeding from the rectum or blood found in the stool can also be a sign of colon cancer. Continuing abdominal pain, cramps, gas, weakness, fatigue and unexplained weight loss could all be signs of rectal cancer in the patient (Staff,
What the recent studies are showing is pretty scary. Our country has the highest number of colon-rectal cancer cases being reported in the entire world. And the disease is equally extensive among males as they are in females. In fact the disease today is killing more Americans than it ever did before. To some it is too embarrassing a subject to talk about. But it must be realized that cancer and deaths resulting from that are much more serious things and should be dealt brushing aside all sorts of inhibitions.
The world we live in can be wonderful at times,but can also be dangerous and danger isn’t a good place to start at.The word cancer seems terrifying when someone thinks about it and they should be because there is a lot of types of cancer from all over the word.Cancer is the leading causes of death everywhere you go and it happens from different parts of the body.From someone that doesn’t understand cancer it’s very important to know about the aspects in which they come around.They way a cancer forms,symptons that are caused,and the way each cancer type is treated is very important to consider.
Colon cancer develops in the part of the gastrointestinal tract that absorbs water and minerals before waste products are disposed via the rectum. In women endometrial cancer is related to colon cancer. This type of cancer is the second leading cause of death due to cancer in the United States. Over one-hundred fifty thousand individuals will be diagnosed this year and this cancer will probably be responsible for about 47,900 deaths in 1999 (http://www.cancer.org). Most colon cancers are adenocarcinomas that develop from the glandular cells. Ninety percent of all colon cancer cases will develop in individuals after 50 years of age. Ninety percent of all tumors arise from polyps that are commonly found in people older than 50. Prevention includes regular exercise and a diet high in fiber. The most important risk factor is age. Medical screening includes a yearly blood occult test after age 50 and a colonoscopy every 3 years after age 50. Regular screening detects polyps that have become precancerous. If regular screening is not done, the cancer is not detected until blood is found in the...
Colon Cancer is cancer of the colon, or large intestine. Rectal cancer is cancer of the last few inches of the colon. Together, they're often referred to as colorectal cancers. Most cases of colon cancer begin as small, harmless clumps of cells called polyps. Over time some of these abnormal growths may become colon cancers. Polyps may be small and produce few, signs of sickness. Because of this, doctors recommend regular screening tests to help prevent colon cancer.
Many cancers seem to have been inherited DNA mutations. These mutations cause an extremely high risk of developing certain types of cancer, such as Pancreatic Cancer. Many of these DNA changes have been shown by researchers in recent years. Most of the time, DNA in non-inherited cases of Pancreatic Cancer seem to be the same as those who have inherited it.
Each stage is characterized by an A, B, or C letter, depending on the degree to which the symptoms present themselves. The differences in each stage are as follows: stage 1 is when the cancer is either found in one ovary or both, stage 2 the tumor is found in one or both ovaries and extends to other pelvic structures, stage 3 the cancer has spread beyond the pelvis to the lining of the abdomen or to the lymph nodes and finally in stage 4 the cancer has spread to other organs in the body including the liver or lungs (Ovarian Cancer National Alliance). Cancer is “staged” by taking a sample of the infected tissue surgically and sending it to a lab for examination. Staging is crucial in order for medical professionals to determine which course of treatment would be the most effective for the given patient. If misdiagnosed, an entire area affected by this disease could potentially be missed and left untreated.
Cancer is a deadly disease that affects millions of American families each year. In cancer, cell division isn't controlled. Usually, cells have to go through a set of checks and balances before they divide, in cancer that is nonexistent. The cells just keep duplicating until they eventually form disorganized clumps called tumors. Tumors can either be, benign, meaning that they do not possess the power to metastasize to surrounding areas. If a tumor has the power to metastasize, it is classified as a malignant tumor. In simple terms, a benign tumor is not cancerous, and a malignant tumor is. Cancer cells cannot perform the necessary functions they were created for. Some types of cancers, like pancreatic cancer, cannot be cured. Other cancers such as melanoma and breast cancer have high survival rates when caught early. The four major types of treatments used to treat cancer include, surgery to remove the affected organ, radiation, chemotherapy, or biological treatments.
Cancer Cancer is a disease in which cells grow out of control and invade, erode, and destroy normal tissue. Damaged genes cause this development of cancer. These damaged genes are often a factor caused by such things such as the environment, and can be influenced by inherited factors. As the very early damaged cells divide they can evolve into a malignant cell population, and lose the control mechanism that govern normal cell division. These malignant cells can then go on to form solid tumours that start to destroy normal tissue.
Randy is at rish for colorectal cancer. While it estimates that the contribution of the enviornment in people with colon cancer is 65%, the other 35% is genetic factors, and Randy's cousin, and father have been diagnosed.
My grandfather on my mum’s side died of colon cancer, colon cancer is where the body extracts water and salt from solid wastes. Colon cancer happens when out of control cell growth occurs in the large intestine. Colon cancer can be caused through genetics; a genetic predisposition that can be inherited from family members, but most colon cancer occur in people without a family health history.
Over the past few decades, cancer has become a very prominent disease. There are many different types of cancer and many different causes of the the disease. Most cancers are caused by a genetic mutation. The most common type occurs when a cell is divided. Proto-oncogenes, which are alleles in normal cells, mutate to form oncogenes.
Colon cancer is a cancer of large intestine (colon), the lower part of your digestive system. Rectal cancer is cancer of the last several inches of the colon. The type of colon cancer is adenocarcinomas.
