Colon cancer also known as colorectal cancer is cancer cells that are present in the long tube known as the large intestine and rectum. Some tumors found in this area are called polyps are not cancerous; however, tumors that are malignant are cancer. The polyps can be removed without the worry of spreading the disease, as they are not cancerous. Cancer of the colon or rectum on the other hand, can spread to other areas of the body and tissue. This occurs when cancer cells break away from the tumor and travel to other areas of the body, which is called metastasis, and can spread to the liver or the lungs. After metastasis occurs, the prognosis for a full recovery is dim.The causes of Colon Cancer
As with practically all cancers, the exact causes are not known, however, risk factors that are present may help lead scientists to the answer. The risk factors for developing colon cancer include the following.
Diet
Individuals that eat a diet high in fat are at a higher risk of developing colon cancer. Those that eat a balanced diet and include such things as whole grains, fruits, and vegetables decrease their chances of developing colon cancer.
Colon polyps
Physicians believe that untreated polyps develop into colon cancer. In the majority of cases, these polyps are benign; however, over years without being removed the cells can change due to chromosome damage, which can become cancerous.
Ulcerative colitis
Ulcerative colitis can be a cause of colon cancer. This disorder brings on inflammation to the inner lining of the colon. In the majority of individuals with ulcerative colitis their chances of colon cancer begins to increase after 8 to 10 years of living with the disorder. Research shows colon cancer and individuals with ulcerative colitis include after 10 years 2.5% had colon cancer, after 30 years the rate rose to 7.6%, and after 50 years, it had risen to 10.8%.
Heredity
Past history of relatives with colon cancer increases the risk of this type of cancer. However, 80 percent of all patients do not have a family history of the disease.Symptoms of Colon Cancer
Many people do not realize they have colon cancer due to the fact that the symptoms may not be present for many years after the development of the cancer cells. The symptoms can differ according to the location of the cancer or the tumor. The right colon is very large and in most cases, the symptoms are not apparent except for the possibility of becoming anemic due to iron deficiency due to the cancer. The left colon on the other hand is smaller and can cause partial or complete obstruction of the bowel bringing on constipation, diarrhea, cramps, bloating, and abdominal pain.
The main symptoms that are present with colon cancer include weakness, fatigue, change in bowel movements, shortness of breath, diarrhea, constipation, weight loss, cramps, bloating, abdominal pain, irritable bowel syndrome, peptic ulcer disease, Crohn’s disease, ulcerative colitis, and diverticulosis.

Liver cancer survival rates indicate the chances a cancer patient has of surviving the disease for a specified length of time. The rates are by no means a definite indicator of what will happen to a patient; they can at best predict a patient’s chances of what might happen to him, if a type of treatment plan is opted for, based on what has happened to other patients in similar circumstances.Liver cancer is a very serious disease that can be fatal within a year of being diagnosed for some patients. This is because the symptoms you will notice with liver cancer won’t usually appear until it has become a serious medical condition. There are two major types and they are called hepatocellular and metastatic.Primary liver cancer instances in the United States are increasing over the years as are metastatic cancer or cancer that spreads to the liver from other parts of the body. These cancers are not labelled as liver cancer but as metastatic cancer of whatever organ they originated from (i.e. metastatic colon cancer for cancer of the colon spreading into the liver).The liver makes the different proteins that your body needs, which include enzymes, hormones, antibodies, and other substances necessary for the proper functioning of your body. It is the power plant of your body since it is the primary source of energy. It also filters your blood to remove toxins and produces bile to help in the digestion of fat. It is the most parsimonious organ in the body, extracting anything that can be used from your blood and storing it for future use.Hepatic tumors also called Liver cancer. Hepatic tumors is are tumors or growths on or in the liver. There are many forms of liver tumors premary is Malignant. Malignant, primary liver cancer is hepatocellular carcinoma (also named hepatoma, which is a misnomer). These growths can be benign or malignant (cancerous). They may be discovered on medical imaging (even for a different reason than the cancer itself). Most of the time when cancer is found in the liver, it did not start there but spread to the liver from a cancer that began somewhere else in the body.The other leading cause of liver cancer is chronic infection with the hepatitis C virus. So far, there is not a vaccine to protect against hepatitis C infection. The best prevention against hepatitis C as well as hepatitis B (for those who have not been vaccinated) is understanding how the viruses are spread and how to avoid contamination.On a broad basis, we can classify liver cancer as primary liver cancer and secondary cancer. When cancer originates in the liver itself, it is called as primary liver cancer. Liver cancer is known as secondary liver cancer when it originates in some other part of the body and then spreads to liver (e.g. due to proximity of liver to the place where cancer originated in the body). Hepatoma and bile duct cancer are the two main types of liver cancer.
