Where Does Pancreatic Cancer Begin
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Mesenteric nodes: As colon cancer grows from premalignant cells in the mucosa of bowel it invades the muscularis reaching serosal outer surface (Dukes B). It then invades nodes of the mesentery C1 expanding to 4 or more nodes C2 and then along the mesenteric lymphatics to liver. Subpopulations in the primary however can eventually spread directly to lung or bone depending on their surface antigens. ...Read more
Early: Unfortunately, it appears that pancreatic cancer spreads to other organs very early in its development before the cancer is even detectable. We believe that the cancer cells become migratory and get into the local lymphatic and vascular channels, as well as moving along nerve fibers. The cancer cells then have to "set up shop" in a new place, the most common being lymph nodes, liver, lung, etc. ...Read moreSee 2 more doctor answers
Symptom of abdominal: Many different Cancers in the abdomen can cause early satiety. It is a presenting symptom for stomach, Ovarian cancer as well as pancreatic cancer(sometimes). If it persists or you are losing weight, you should consult your doctor without a delay of more than 1 or 2 weeks. ...Read more
Lymphatics and blood: Breast cancer can advance locally in the breast, to the skin and to the chest wall. It can spread regionally through the lymphatic channels to the lymph glands in the axilla (armpit), below and avove the collar bone and to the side of the neck. It can spread through the blood stream to distant organs such as bones, liver, lung, brain and othe organs. This is called distant metastasis. ...Read moreSee 1 more doctor answer
Depends: Invasive breast cancer has the ability to spread but not all invasive cancers do spread, especially if caught early. Cancer grows at different rates in people depending on age, hormone status of the tumor and genetic make up of the person. It is important to understand all of your options regarding treatment. ...Read moreSee 2 more doctor answers
Colon more specific: The intestinal tract is composed of the small intestine, large intestine or colon, and rectum. Virtually all cancers of this system arise in the colon and rectum, with cancers of the small intestine exceedingly rare. Therefore, intestinal cancer generally refers to colon or rectal cancer, which is more anatomically specific. Adenocarcinoma is the most common type of cancer that occurs. ...Read more
Polyps.: Polyps (adenomas) are small, benign masses that can form within the colon. The life cycle of the mucus membranes of the colon becomes disrupted, either from genetic or environmental reasons, causing growth of polyps. If polyp growth continues abnormally, they have the potential to develop into an invasive lesion and become cancerous. ...Read moreSee 1 more doctor answer
From polyps usually: Almost all colon cancers start off as a polyp, hence the push for colonoscopy screening looking for polyps. Only 20% of colon cancers are hereditary, meaning the rest are environmentally related to foods we eat and chemicals we are exposed too. If you are over 50 or have risl factors get regular colonoscopies. ...Read moreSee 1 more doctor answer
Anaplastic Cancer: Anaplastic thyroid cancer is the least common form, but also the most aggressive. It is usually fatal, and spreads by direct extension, so that the cancer cells push outside of the thyroid and grow into nearby neck structures, including muscle, the trachea (windpipe), and blood vessels, including the carotid artery and the jugular vein. ...Read moreSee 3 more doctor answers
Does pancreatic/biliary duct, stomach, colon cancer or leukemia skip a generation? Please, need some answers?
Unrelated: These tumors are independent and unrelated to a genetic passing down of a familial situation such as with the BRACA gene in breast cancer. Genetic association occurs in about 5% of cases and 95% of cancers are due to contact with carcinogens or viruses. It has now been shown that intrinsic gene factors can be passed down and skip a generation such as with the partial sequence of the MMTV virus. ...Read more
It varies a lot: There is good treatment for stage 4 colon Cancer. Most people live for 2-3 years when they take chemotherapy. If the liver tumor is small it can even be removed with surgery. Tell us about the dates of your diagnosis and what type of chemotherapy you have used and for how long? Then we can give you a better estimate of expected survival. ...Read more
Abdominal organ. It is digestive organ: it secretes enzymes into the small bowel which break down food and help its absorption. It is also an endocrine organ: it produces hormones involved in sugar control and control of digestion. Insulin is one of these hormones. Diabetics either lack Insulin (type 1 diabetes) or have inadequate ...Read more
