Cancer (Definition)

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

Is ectopic hamartomatous thymoma a benign or malignant tumor?

Is ectopic hamartomatous thymoma a benign or malignant tumor?

Depends: A thymoma is a malignant tumor of the thymus, and the seriousness depends on details in the pathology report. An ectopic thymus and a hamartoma are both benign, but if the report says "thymoma" then it is probably malignant although not necessarily very serious if completely removed. Discuss with your surgeon! ...Read more

What is the percentage of lung tumors being benign vs cancerous?

What is the percentage of lung tumors being benign vs cancerous?

Details matter: Many lung nodules are benign. This will depend on were you live. Lung nodules can be granulomas, infections, fungal infections, benign growths such as hamartomas, and finally cancerous. It is important to have either serial imaging or a biopsy if a lung nodule is found. There are currently guidelines for this that a pulmonary medicine specialist or thoracic surgeon should follow. ...Read more

Are pancreatic malignant tumors hypoechoic ?

Are pancreatic malignant tumors hypoechoic ?

Yes: The typical echogenicity of the pancreas is hyperechoic to adjacent fat. A hypoechoic mass within the pancreas can be benign or malignant. If you have a hypoechoic mass in the pancreas at age 30, you should undergo an MRI or ct of the abdomen to evaluate it further unless by ultrasound it is obviously cystic. ...Read more

Solitary, solid nodule with intranodular flow and follicular neoplasm cells. Afirma came back suspicious. What's likelyhood of malignancy?

Solitary, solid nodule with intranodular  flow and follicular neoplasm cells. Afirma came back suspicious. What's likelyhood of malignancy?

Ask your doctor: The doctor who ordered your biopsy has responsibility to explain to you the meaning of the results. If the biopsy shows neoplastic cells, that usually means Cancer cells. But you should get this clarification from your doctor. ...Read more

What is the frequency of benign colon tumors compared to cancerous tumors?

Small and about 5%: Other than for congenital polyposis the majority of lesions arise in a field effect initiated by the polyoma virus. Contrary to the belief that adenomatous polyps convert to malignant polyps and then Ca this occurs in about 5 % of pts. 95% arise from premalignant cells in the viral or carcinogen field. ...Read more

What distinguishes cancer cells from the cells of benign neoplasms?

What distinguishes cancer cells from the cells of benign neoplasms?

Disordered growth: Benign tumors grow locally and do not spread. Under the microscope, the cells look like the gland they are from and they are not invading. Cancer cells have disordered growth, frequently do not look like the originating gland and show invasion. ...Read more

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

Power to invade: Tumors are in fact caused by the accumulation of a series of genetic mutations. If something is going to be cancer, the mutations destabilize the genome and eventually mutations give the ability of the cells to invade and spread as they do early after conception. The idea that tumors are "cells dividing too rapidly" is fundamentally wrong and confusing -- it's the loss of controls. ...Read more

Pathology cytology report of Left thyroid biopsy says NO malignant cells... changes suggestive of Colloid nodule/ nodular Goiter. What's next?

MNG + cyst: Hello ~ this is a nodule in MNG (multi-nodular goitre). Previously thought to have no risk of Ca and DOMINANT nodule to have 1% risk and solitary nodule 10% risk. Retrospective studies now show up to 13.7% risk of cancer overall in MNG. Thats high. I would see a surgeon to discuss if this warrants thyroidectomy. thanks ...Read more

Is biliary duct cancer a form of primary liver cancer?

Is biliary duct cancer a form of primary liver cancer?

No: Primary liver cancer is when the liver cells themselves, the hepatocytes, transform into cancer cells. Bile duct cancer is when the cells lining the bile duct transform into cancer. Primary liver cancer tends to grow large nodules in one place, and doesn't give a lot of symptoms until the tumors are large. Bile duct cancer tends to obstruct the bile ducts and create symptoms, such as jaundice. ...Read more

What is a mucinuos cystic neoplasm of the pancrease (pancrelipase)?

What is a mucinuos cystic neoplasm of the pancrease (pancrelipase)?

Complicated: There are three possible entities to which you are referring. Mucinous cystadenoma (benign), mucinous cystadenosarcoma (malignant), and intraductal papillary mucinous tumor (benign or malignant). All three have certain appearances on imaging studies. They can be treated surgically and if malignant, have a better prognosis than "traditional" pancreatic cancer (adenocarcinoma). ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more

Gallbladder (Definition)

The gallbladder is a sac-like structure located under the right lobe of the liver. It is attached to the common bile duct via the cystic duct. The gallbladder can store bile when the bile is not needed, and can squeeze bile into the bile duct and intestine for digestion when a person eats larger ...Read more
