Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body.
Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place.
Liver cancer is cancer that begins in the cells of your liver. Your liver is a football-sized organ that sits in the upper right portion of your abdomen, beneath your diaphragm and above your stomach.
Several types of cancer can form in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the main type of liver cell (hepatocyte). Other types of liver cancer, such as intrahepatic cholangiocarcinoma and hepatoblastoma, are much less common.
Cancer that spreads to the liver is more common than cancer that begins in the liver cells. Cancer that begins in another area of the body — such as the colon, lung or breast — and then spreads to the liver is called metastatic cancer rather than liver cancer. This type of cancer is named after the organ in which it began — such as metastatic colon cancer to describe cancer that begins in the colon and spreads to the liver.
Most people don't have signs and symptoms in the early stages of primary liver cancer. When signs and symptoms do appear, they may include:
Liver cancer levering construction meta status Tommy remove of liver tumor and cancer spread to liver.
Esophagus is the food pipe which serves the purpose of carrying food from mouth to stomach and its cancer is 6th most common cancer worldwide. Usually occurs in elderly patients. Symptoms often include difficulty in swallowing (dysphasia) and weight loss. Other symptoms may include pain when swallowing (retro sternal pain), a hoarse voice, enlarged lymph nodes (glands) around the collarbone, a dry cough, and possibly coughing up or vomiting blood.
The most common causes are: tobacco, alcohol, very hot drinks, poor nutrition and hyperacidity (acid reflux). The disease is diagnosed by biopsy done by an endoscope (a fiber optic camera). However CECT chest and abdomen is important to plan the treatment. Treatment is based on the cancer's stage and location, together with the person's general condition and individual preferences. Surgery is the mainstay of treatment in patients with operable disease. Small localized squamous-cell cancers may be treated with surgery alone with the hope of a cure. In most other cases, chemotherapy with or without radiation therapy is used along with surgery. Larger tumors may have their growth slowed with chemotherapy and radiation therapy followed by surgery. Usually surgical procedure needs complete removal of esophagus along with all nodes related to disease and replacement of esophagus by stomach In the presence of extensive disease or if the affected person is not fit enough to undergo surgery, palliative care is often recommend.
Esophageal cancer can also be done by laparoscopically.
Pancreatic cancer begins in the tissues of your pancreas — an organ in your abdomen that lies behind the lower part of your stomach. Your pancreas releases enzymes that aid digestion and produces hormones that help manage your blood sugar.
Several types of growths can occur in the pancreas, including cancerous and noncancerous tumors. The most common type of cancer that forms in the pancreas begins in the cells that line the ducts that carry digestive enzymes out of the pancreas (pancreatic ductal adenocarcinoma).
Pancreatic cancer is seldom detected at its early stages when it's most curable. This is because it often doesn't cause symptoms until after it has spread to other organs.
Pancreatic cancer treatment options are chosen based on the extent of the cancer. Options may include surgery, chemotherapy, radiation therapy or a combination of these.
Bile duct cancer arises from the cells that line the bile ducts, the drainage system for bile that is produced by the liver. Bile ducts collect this bile, draining it into the gallbladder and finally into the small intestine where it aids in the digestion process. Bile duct cancer is also called cholangiocarcinoma.
Bile duct cancer is a rare form of cancer, with approximately 2,500 new cases diagnosed in the United States each year. There are three general locations where this type of cancer may arise within the bile drainage system:
Within the liver (intrahepatic) affecting the bile ducts located within the liver Just outside of the liver (extrahepatic or perihilar) located at the notch of the liver where the bile ducts exit Far outside of the liver (distal extrahepatic) near where the bile ducts enter the intestine (called the ampulla of Vater) Bile duct cancers are most commonly found just outside of the liver in the perihilar area and least commonly found within the liver.
Intestinal cancer occurs when cancerous cells form in the small intestine (or small bowel). When cancer develops in the large intestine (also called the large bowel or colon), it is called colorectal cancer. The small intestine connects the stomach to the large intestine. It is divided into three sections: the duodenum, jejunum and ileum. Most types of small intestine cancer develop in the duodenum.
As with most cancers, intestinal cancer develops when defective or mutated cells grow out of control and form a tumor. Intestinal cancer, also called small intestine cancer or small bowel cancer, usually starts in the lining of the small intestine and may spread to other parts of the body. Most cases of intestinal cancer develop in the duodenum, or upper part of the organ.
Intestinal Cancer treatment is many complete removal of Cancer by surgery this can be done by laparoscopically.
Colon cancer is a type of cancer that begins in the large intestine (colon). The colon is the final part of the digestive tract.
Colon cancer typically affects older adults, though it can happen at any age. It usually begins as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the colon. Over time some of these polyps can become colon cancers.
Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent colon cancer by identifying and removing polyps before they turn into cancer.
If colon cancer develops, many treatments are available to help control it, including surgery, radiation therapy and drug treatments, such as chemotherapy, targeted therapy and immunotherapy.
Colon cancer is sometimes called colorectal cancer, which is a term that combines colon cancer and rectal cancer, which begins in the rectum.
Signs and symptoms of colon cancer include:
Signs and symptoms of colon cancer include:
he wall of the gallbladder has 4 main layers of tissue.
