Are mast cell tumors people tumors or dog tumors?

Are mast cell tumors people tumors or dog tumors?

I know humans: I don't know about dogs, but humans can get systemic mastocytosis. An uncommon clonal growth of mast cells. Mast cells may also be reactive, such as from allergies. ...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

Are carcinoid tumors carcinoma? Is malignant metastatic stomach carcinoma that's hereditary a carcinoid cancer? carcinoid Neuroendocrine tumors?

Are carcinoid tumors carcinoma? Is malignant metastatic stomach carcinoma that's hereditary a carcinoid cancer? carcinoid Neuroendocrine tumors?

Complicated question: Carcinoids are carcinomas, usually more slow growing than adenocarcinomas. For information in this topic you may consult this link: http://www.webmd.com/cancer/carcinoid-tumors#1 ...Read more

What about neuroendocrine (islet cell tumors)?

What about neuroendocrine (islet cell tumors)?

Interesting tumor: Overally, neuroendocrine tumors are often capable of over-producing hormones that your body naturally makes. Islet cells are cells that are naturally present in the pancreas and produce a number of hormones, most notably insulin. Insulin helps you break down and digest sugars. Patients with an islet cell tumor can produce too much Insulin resulting in weight & gain and low blood sugars. ...Read more

Testicular cancer: what is a non seminomous germ cell tumor?

Potentially serious: A nonseminomatous germ cell tumor is a malignancy that has multiple origins within the testicle. It is less common, but potentially more serious, than seminomas of the testicle. Early and aggressive treatment is necessay and can lead to cure in many patients that present with limited disease. Systemic chemotherapy is now available for patients that present with advanced tumors. ...Read more

What is extracranial germ cell tumor of childhood?

What is extracranial germ cell tumor of childhood?

Rare family: This is a family of tumors that can be diagnosed by a pathologist (i suggest you get a consensus from 3 of us) that resemble to some degree the gametes and/or the cells of the unborn child. They run from totally benign to very malignant; thankfully today's treatment produces many good responses. ...Read more

With germ cell tumor that to deal with germ cell tumor cancer?

Clarify, can be CA.: These can be cancer. These are tumors of germ cells which can be from the gonads, or ovary and testis, or from outside these areas and occur during embryonic development. These can be cancerous or non-cancerous. Prognosis varies. Some, like seminoma, have a very good prognosis. ...Read more

Pathologic diagnosis....Resected thymus shows reactive b cell hyperplasia vs low grade b cell lympho proliferative disorder. Is this lymphoma?

Pathologic diagnosis....Resected thymus shows reactive b cell hyperplasia vs low grade b cell lympho proliferative disorder.  Is this lymphoma?

Could be...: Certain lymphomas grow so slow that sometimes it is difficult for the pathologist to make the call between malignant or not. I suspect they may do additional work on the specimen and that your doctor will evaluate you further with labs, additional scans or another biopsy. If you have not seen a hematologist, maybe this is the time. Don't panic, just follow up his/her lead. Best to you. ...Read more

How useful are circulating tumor cells as a tumor marker?

For certain cancers: Circulating tumor cell count is done and quite useful to see the response of treatment given for certan type of metastatic cancers only -i, e, metastatic breast cancers, prostate, and colon cancer. Not indicated / used for other type of cancers and not used for earlier stage of cancer. ...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

Extragonadal germ cell tumor?

The gonads produce: Sperm in men (&testosterone) and eggs/ova in women (& estrogens), and these are also the sites of germ cell tumors. Outside the gonads, the mediastinum and brain (pineal) are the most common extragonadal sites. These are known to produce markers (hcg, alphafeto-protein) and responsve and curable with chemotherapy. Hope this helps. ...Read more

Granulosa cell tumor can be acquired from sex?

Granulosa cell tumor can be acquired from sex?

No: Granulosa cell tumors of the ovary (and more rarely the testicle in men) are not aquired from sexual activity. These are rare tumors and know specific risk factors are known. However, some studies have shown that the majority if these tumors have a mutation in the flox2 gene. It is not known what causes this mutation to occur or if it is the cause if the tumor. ...Read more

How to differentiate primary tumor cells from cells of metastases?

How to differentiate primary tumor cells from cells of metastases?

Close exam: primary tumor cells are well defined, arising in the organ that initiates the lesion. A cancer of the breast when biopsied shows adenoca cells of breast origin. When metastatic to liver or lung, biopsy will show the same cells as the primary . If the lesion arises in the liver it is not metastatic in terms of cells seen but liver tumor cells or hepatoma. ...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

What percentage of ependymoma brain tumors are benign?

What percentage of ependymoma brain tumors are benign?

0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read more

Is hurtle cell neoplasm defined as cancer?

Is hurtle cell neoplasm defined as cancer?

Not necessary: Hurtel cell neoplasm can be adenoma (not cancer) or carcinoma (cancer). There is not much difference between the two with regards to age, sex, or history of head and neck radiation. However, hurtle cell carcinoma (cancer) tends to be larger in size (4.0 +/- 0.4 cm) compared with hurtle cell adenoma (2.4 +/- 0.2 cm). ...Read more

Which distinguishes cancer cells from the cells of benign neoplasms?

Which distinguishes cancer cells from the cells of benign neoplasms?

Genome destabilized: The key to cancer is that enough mutations have accumulated to render the genome itself unstable. Eventually a clone will acquire the ability to invade and spread. We can pick this up using molecular biology techniques. They also look different, but it takes a pathologist several years to learn to tell all the subtleties. ...Read more
