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
Are benign and malignant nasal tumors common or rare? What are the statistics for benign and malignant nasal tumors and who mostly gets them?
Nasal tumors: The most common tumors of the nasal cavity are squamous cell carcinoma and adenocarcinoma variants. They are twice as common in men versus women, and the median age of presentation is in the early to mid 60's. The patient will usually present with chronic sinus congestion or recurrent nasal obstruction. Risk factors include tobacco smoke and occupational exposure (wood dust and textile dust). ...Read more
Curable? No: Lung nodules are very common, and over 95% are benign scars that require no "cure". They don't go away, and therefore are not "cured" but they are harmless. The 4-5% of lung nodules that are cancer require some form of treatment and many of these are curable. This depends upon thorough evaluation of the nodule, staging and treatment by experienced teams. ...Read moreSee 1 more doctor answer

Lumps: Tumor is a nonspecific term for a growth which may be benign or malignant. Malignant tumors grow and often spread while benign tumors may grow but don't spread to distant tissues. A cyst is a fluid filled growth which is usually benign. Even benign breast tumors and cysts may cause pain and tenderness and may require surgery. ...Read moreSee 2 more doctor answers
Why are tumor deposits in colon cancer considered as lymph nodes when there are no lymphovascular invasion, because of td it's becoming a stage 3?
Local spread: If the tumor deposits are located away from the main primary, then most authorities consider them to be equivalent to a positive lymph node(s). Most likely these deposits got there via lymphovascular invasion even if the pathologist could not see that histologically on the slides. The ajcc also considers discontinous tumor deposits as n1c in the pathological staging system. ...Read moreSee 1 more doctor answer
Could colon cancer T4 , no positive nodes, but isolated tumor deposits found in pericolic tissue be cured with chemotherapy and radiation?
Surgery is the best : Shot. A T4 lesion means the cancer has grown outside the walls of the colon and into adjacent structures. If all of the cancer can be surgically removed you can be cured.

Eradicate: Rai can eradicate thyroid cancer cells from distant sites such as the lung or bone. It may not be completely effective with everyone, however, as some tumor cells at these distant sites have lost the ability to take up the iodine like normal thyroid cells can. In such cases, repeat and/or higher doses may be required. ...Read moreSee 1 more doctor answer
Questionable: When lymph nodes are examined it is to see if the are involved in an inflammatory process or have a primary or metastatic malignancy ongoing. Touch preps may help to define the presence of abnormal cells but if they do, immunohistochemistry is performed with a battery of monoclonals to see if a specific malignancy is present. At times normal skin and glandular elements are found in nodes ...Read more
My son has pancreatic cancer which is also in the liver. The liver tumor is small. They found no other places with cancer. Why not remove liver tumor?
Depends: It really depends on type of cancer. Adenocarcinoma is not resectable once outside the pancreas because there are other areas that u can't see yet.

Often: They are either metastatic lesions that spread from other parts of the body, or they are "primary" lung cancers that originated in the lung tissue. Most often if multiple tumors, they would be metastatic lesions, but if there was a single spot seen in a smoker, it may be a primary tumor. ...Read moreSee 1 more doctor answer
No: Benign lung nodules are not rare and are found during routine chest x-rays or, more likely ct scans. The most common are hamartomas or adenomas that are totally innocent if they are in the outer lung as usual but can block a lung if they are in one of the bronchial tubes. Although, pet scans can help determine that these are benign, some require surgical removal to assure that they are benign. ...Read more
