For colon cancer,Peritoneal Carcinoma's, roughly what percentage of those malignant tumors are cancerous.I read malignant tumors are 100% cancer.
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
Even in Stg I: 25% mortality at 5 yrs for colon/rectum. For those invading into and through the bwel wall, or with metastasis to nodes, the survival may be below 50% at 5 years. Only about 5% survive with metastasis. These are acs figures. Ajcc 6th: 65% os, 93% stg1, 83% stg 2; 60% stg3, 8% stg 4. ...Read more
Contained: No evidence of invasive carcinoma on the pathology report for colon cancer means that the cancer appears to be contained and has not spread, such as into the muscle layer of the colon and beyond. This should imply a higher likelihood for cure if one follows the recommendations of one's oncologist. ...Read more
Iam 63 old have soft tisse mass in descedig colon measres 67*42*38 mm with focal liver lesion in rt lobe
show adeno carcinoma with necrosis?
Colon mass: Cheryl, this is difficult to answer. If you have a biopsy diagnosis of colorectal carcinoma, then the liver lesion may represent a metastasis. It could also represent only a liver hemangioma. Only a liver biopsy of the lesion is definitive. Red cell tagging studies sometimes can be definitive noninvasive study for liver hemangioma but does not have 100% sensitivity and may give false negative. ...Read more
Colon surgery:tumor size=2cm.Pathologic staging(pt3, n1b, mx).2/17 lymph nodes show metastatic.Margins of resection free of carcinoma.Need chemotherapy?
Yes: Chemotherapy regimens based on the drug Fluorouracil (5-fu) have been part of the treatment for high-risk stage ii or stage iii colon cancer. Many clinical trials have shown that these regimens improve overall survival primarily by reducing the high risk of recurrence within the first two years after surgery. ...Read more
Squamous cell carcinoma, no skincancer. Normal x ray/ct Scan of lungs/abdomen/breasts/Colon. Metastasis in lymphnodes under armpits/collarbone. Cough, weightloss, SOB. Ex smoker, Nicorette addict. No primary tumour found. What type of cancer?
Squamous: Disseminated squamous cell carcinomas with no obvious primary often are ultimately found to have arisen in the nasal sinuses. There are even protocols for treating "squamous cell carcinoma of unknown primary". We may still have something to offer that's worthwhile. Best wishes. ...Read more
Cancer fever: A fever is an common symptom related to many conditions, mostly benign. An increase in body temperature is most often a biological response to a viral or bacterial infection. In some cases, however, a persistent fever can be related to cancer. Most common types of cancers associated with fever- lymphoma and leukemia. If you have had a persistent low grade temperature best to be evaluated. ...Read moreSee 1 more doctor answer
Colon cancer: Genetic alterations (changes in the dna or ways in which dna is regulated) in the epithelium of the colon (the cells that line the colon) are the source of colon cancer. These changes can occur for many reasons, some of which are genetics alone (family predisposition), a combination of genetics and environment (foods, toxins), or the we don't exactly know category. ...Read more
Cancer of the colon: Cancer that forms in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). There are estimated 103, 170 (colon); 40, 290 (rectal) new cases and 51, 690 (colon and rectal combined) deaths from colon cancer in us in 2012. Screening with colonoscopy started at age of 50. ...Read moreSee 2 more doctor answers
Cancers: Cancers are abnormal, rapidly growing cells that do not know when to stop growing. These abnormal cells can damage local tissues, can attach to nearby organs or structures, can spread to lymph nodes, or can spread to other organs through the blood stream. Their growth damages what they are attached to, and often cancers encourage new blood flow to themselves. Cancer can grow in the colon. ...Read moreSee 1 more doctor answer
Not always: Colon cancer tends to not have any signs or symptoms when it is early (when it is easiest to treat). That is why screening colonoscopies are so important, to remove any polyps that may become cancer, and to directly look for cancers. Colon cancer can cause bleeding from the rectum, tiredness from anemia, stool changes, or abdominal pain. Other things can cause this too. Best to be seen if ?S. ...Read moreSee 1 more doctor answer
Usually not: Early stages of colon cancer often have no symptoms. Colon cancer has long developmental stages starting out as polyps and can take yrs to develop, hence screening colonoscopy is done every 10 yrs for normal folks. Polyps can be removed during colonoscopy. Advanced cancer can cause pain by obstructing bowel, spread to liver, bone, brain, lung etc. See doc regulalry. Good luck. ...Read moreSee 2 more doctor answers
Early detection!: The best thing that improves the chances of curing colon cancer is early detection. So preventive health care and screening are key. All adults should have a colonoscopy at age 50 to look for cancers or early cancers, usually as polyps. If you have a strong family history or certain conditions it is recommended you get earlier screening.Once detected, colon ca usually is cured by surgery, or drugs. ...Read moreSee 1 more doctor answer
Very complicated: Monoclonal theory says that just like we are a living thing, we are born, we have jobs to do and then we die, each cell has a similar cycle of birth, life, and death. Cancer occurs when a cell develops so many mutations that it does not follow that cycle and does not die but can still divide itself and hides from our immune system which is there to detect abnormal cells and destroy them. ...Read moreSee 1 more doctor answer
Not enough info: Colon cancer can present with or without symptoms. Common symptoms include change in stool caliber/consistency, rectal bleeding or blood with bm, abdominal pain, anemia. If you have not been screened, you should consider the various screening options for colon cancer, includine a stool test to check for blood, colonoscopy, or sigmoidoscopy. If you are having bleeding, you need a colonoscopy. ...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
Lymph nodes: Lymph nodes are the way colon cancer cells usually escape the colon. It can grow through the colon into the surroundings. Finally it can move from lymph nodes into the blood stream that flows to the liver. When the colon is examined, and if lymph nodes are involved, chemotherapy is recommended. ...Read moreSee 1 more doctor answer
Get tested: There are many tests that have been developed to test either a patient with concerning symptoms or just as a routine screening exam in an a symptomatic patient. Each individual situation is different. Testing stool for blood or now genetic abnormalities, rectal exam, X-rays such as barium enema or ct scan virtual colonoscopy are examples. Best is colonoscopy as you can both look and do. ...Read moreSee 1 more doctor answer
