How Do They Test for Throat Cancer or Tumors?

---

Does anyone know how they test for throat cancer, throat tumors or cysts? Thank you.
ENTs use flexible endoscopes, which are threaded through the nose and down into the throat so they can see all the structures; nose, nasopharynx, oropharynx, and the top and bottom of the larynx. If they see anything suspicious, a biopsy is taken at that time.
If the biopsy is positive for cancer, then CT scans are ordered in order to locate, determine size, and stage the tumor.  (+ info)

Is the desire to have biological children primitive?

---

As in other recent posts on this subject; I am struggling with my wife's decision to deny me having bio kids. I know it’s selfish, but I want blood children. There are thousands of needy children, the world is over-populated, I will love my adopted children and wonder how I lived without them… but part of me craves my own. I look at pics of my gdprents, my gt-gdprents & my whole family tree, what they have done, how they worked hard for our family and I am so proud that I came from them. I love that I hv the same curly hair as my uncles and my dad, I love that my aunt and I are both so pathetically sentimental, I love that I am stubborn like my dad and that my mom and I dance jigs in the kitchen while the rest of the family stares at us. There is something about being related in blood and finding those roots, connections!
Is this a primitive survival instinct? Should I just get over it? I know adopting children will be a beautiful, rewarding, life-changing event, but i can't kick this.
To try and address some questions, my wife doesn't seem to have the same instinctual urges to have a bio child as me. She also doesn't want to wreck her body and so thinks my desires are selfish (ie my selfish desire to have a bio child will wreck her body). Its her body, i understand her perspective but it creates a big problem for us. A suggestion has been to find a surrogate mother but it kinda blows my mind to think some woman i don't know will carry our child just because my wife doesn't want to.
NO, it is a normal instinct that both men and women have(at least most men and women). Adopting is a great jesture but I am wondering why your wife wants to adopt if she can have her own. Why not have your own and adopt one to have your family. Where is the compromise here from your wife? Just wondering. Good luck  (+ info)

On average, what is the progression rate of malignant brain tumors?

---

That is, how fast do malignant brain tumors such as glioblastoma multiforme or anaplastic astrocytoma typically grow without treatment? I was told they double in size every eleven days, but am not sure how true that is.

Understanding cancer and its side effects. How serious is pneumonia and brain tumors?

---

My father in law has suffered with cancer for over a year. First it was in his esophogaus and then the brain. He became one of the 12% to get through it. Now the tumors are back in the brain and he recently checked himself out of the hospital with pneumonia. He will not talk to anyone about how serious this is. We are worried and any and all info would help. Thanks
He can only now do low dose radiation, as he has had radiation on the same spot within a year. Surgery for some reason was a no and chemo is a no for some reason, as I said he wont talk about it "doesnt want to worry us" Yes, he should have stayed in the hospital, but didnt, and said he wont return. Thanks for the help so far.
i am sorry about ur grief. i will try my best to give the best information i can. but u wouldnt mind if its long enough? do u?
A brain tumor is any intracranial mass created by an abnormal and uncontrolled growth of cells either normally found in the brain itself: neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors).

Primary (true) brain tumors are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain.

In the United States in the year 2000, it was estimated that there were 16,500 new cases of brain tumors[1], which accounted for 1.4% of all cancers, 2.4% of all cancer deaths[2], and 20%–25% of pediatric cancers[2],[3]. Ultimately, it is estimated that there are 13,000 deaths/year as a result of brain tumors[1].

Aside from exposure to vinyl chloride or ionizing radiation, there are no known environmental factors associated with brain tumors. Mutations and deletions of so-called tumor supressor genes are incriminated in some forms of brain tumors. Patients with various inherited diseases, such as Von Hippel-Lindau syndrome, multiple endocrine neoplasia, neurofibromatosis type 2 are at high risk of developing brain tumors.In contrast to tumors originating elsewhere in the body, differentiating primary "brain tumors"—these are the true brain tumors, arising exclusively from cells normally present in the brain itself—into benign and malignant is of relative and limited clinical value, since even histologically-benign tumors grow by infiltration of healthy brain tissue and, in time, tend to transform into malignant forms (anaplastic degeneration). True benign intracranial tumors arise mainly from the meninges (meningiomas; about 95% are benign), pituitary gland (pituitary adenomas) and the myelin sheath of cranial nerves (neuromas or Schwanomas, e.g. acoustic neuroma).

Most primary brain tumors (gliomas) originate from glia: astrocytes (astrocytomas), oligodendrocytes (oligodendrogliomas). There are also mixed forms, with both an astrocytic and an oligodendroglial cell component. These are called mixed gliomas or oligoastrocytomas. Additionally, mixed glio-neuronal tumors (tumors displaying a neuronal, as well as a glial component, e.g. gangliogliomas, disembryoplastic neuroepithelial tumors) and tumors originating from neuronal cells (e.g. gangliocytoma, central gangliocytoma) can also be encountered.

Other varieties of primary brain tumors include: primitive neuroectodermal tumors (PNET, e.g. medulloblastoma, medulloepithelioma, neuroblastoma, retinoblastoma, ependymoblastoma), tumors of the pineal parenchyma (e.g. pineocytoma, pineoblastoma), ependymal cell tumors, choroid plexus tumors, neuroepithelial tumors of uncertain origin (e.g. gliomatosis cerebri, astroblastoma), etc.

From a histological perspective, astrocytomas, oligondedrogliomas, and oligoastrocytomas may be benign or malignant. Glioblastoma multiforme represents the most aggressive variety of malignant glioma. At the opposite end of the spectrum, there are so-called pilocytic astrocytomas, a distinct variety of astrocytic tumors. The majority of them are located in the posterior cranial fossa, affect mainly children and young adults, and have a clinically favorable course and prognosis.

In contrast to other types of cancer, primary brain tumors rarely metastasize, and in this rare event, the tumor cells spread within the skull and spinal canal through the cerebrospinal fluid, rather than via bloodstream to other organs.

There are various classification systems currently in use for primary brain tumors, the most common being the World Health Organization (WHO) brain tumor classification, introduced in 1993.

Secondary or metastatic brain tumors originate from malignant tumors (cancers) located primarily in other organs. Their incidence is higher than that of primary brain tumors. The most frequent types of metastatic brain tumors originate in the lung, skin (malignant melanoma), kidney (hypernephroma), breast (breast carcinoma), and colon (colon carcinoma). These tumor cells reach the brain via the blood-stream.

Some non-tumoral lesions can mimic tumors of the central nervous system. These include tuberculosis of the brain and cerebral abscess
The kind of symptoms brain tumors may cause depend on two factors: tumor size (volume) and tumor location. The time point of symptom onset in the course of disease correlates in many cases with the nature of the tumor ("benign", i.e. slow-growing/late symptom onset, or malignant, i.e. fast growing/early symptom onset).

Many low-grade (benign) tumors can remain asymptomatic (symptom-free) for years and they may accidentally be discovered by imaging exams for unrelated reasons (such as a minor trauma).

New onset of epilepsy[4] is a frequent reason for seeking medical attention in brain tumor cases.

Large tumors or tumors with extensive perifocal swelling edema inevitably lead to elevated intracranial pressure (intracranial hypertension), which translates clinically into headaches, vomiting (sometimes without nausea), altered state of consciousness (somnolence, coma), dilatation of the pupil on the side of the lesion (anisocoria), papilledema (prominent optic disc at the funduscopic examination). However, even small tumors obstructing the passage of cerebrospinal fluid (CSF) may cause early signs of intracranial hypertension. Intracranial hypertension may result in herniation (i.e. displacement) of certain parts of the brain, such as the cerebellar tonsils or the temporal uncus, resulting in lethal brainstem compression. In young children, elevated intracranial pressure may cause an increase in the diameter of the skull and bulging of the fontanelles.

Depending on the tumor location and the damage it may have caused to surrounding brain structures, either through compression or infiltration, any type of focal neurologic symptoms may occur, such as cognitive and behavioral impairment, personality changes, hemiparesis, (hemi)hypesthesia, aphasia, ataxia, visual field impairment, facial paralysis, double vision, tremor etc. It cannot be stressed enough that these symptoms are not specific for brain tumors - they may be caused by a large variety of neurologic conditions (e.g. stroke, traumatic brain injury). What counts, however, is the location of the lesion and the functional systems (e.g. motor, sensory, visual, etc.) it affects.

A bilateral temporal visual field defect (bitemporal hemianopia—due to compression of the optic chiasm), often associated with endocrine disfunction—either hypopituitarism or hyperproduction of pituitary hormones and hyperprolactinemia is suggestive of a pituitary tumor.

Meningiomas, with the exception of some tumors located at the skull base, can be successfully removed surgically, but the chances are less than 50%. In more difficult cases, stereotactic radiotherapy remains a viable option.

Most pituitary adenomas can be removed surgically, often using a minimally invasive approach through the nasal cavity and skull base (trans-nasal, trans-sphenoidal approach). Large pituitary adenomas require a craniotomy (opening of the skull) for their removal. Radiotherapy, including stereotactic approaches, is reserved for the inoperable cases.

Although there is no generally accepted therapeutic management for primary brain tumors, a surgical attempt at tumor removal or at least cytoreduction (i.e., removal of as much tumor as possible, in order to reduce the number of tumor cells available for proliferation) is considered in most cases[5]. However, due to the infiltrative nature of these lesions, tumor recurrence, even following an apparently complete surgical removal, is not uncommon. Postoperative radiotherapy and chemotherapy are integral parts of the therapeutic standard for malignant tumors. Radiotherapy may also be administered in cases of "low-grade" gliomas, when a significant tumor burden reduction could not be achieved surgically.

Survival rates in primary brain tumors depend on the type of tumor, age, functional status of the patient, the extent of surgical tumor removal, to mention just a few factors[6].

Patients with benign gliomas may survive for many years[7],[8] while survival in most cases of glioblastoma multiforme is limited to a few months after diagnosis.

The main treatment option for single metastatic tumors is surgical removal, followed by radiotherapy and/or chemotherapy. Multiple metastatic tumors are generally treated with radiotherapy and chemotherapy. However, the prognosis in such cases is determined by the primary tumor, and it is generally poor  (+ info)

Can a woman have fibroid tumors and still get pregnant?

---

Fibroid tumors run in my family. My mother had grandmother had them and my mother had them and now I know I have them. Will they have any conflict with me getting pregnant?
I also have fibroids, my OB/GYN says that you can get pregnant just may be a little harder. Good Luck  (+ info)

how do I find information on kidney tumors?

how to stop noticing objects with peripheral vision?

---

I kind of sometimes look at something per say computer and I also accidentally see someone sitting next to me I do not look at them directly but I do see them with peripheral vision and they claim I am looking at them. I am not focusing them, but simply see them sitting like watching a big picture your looking at the center but your field of vision covers the edges.
Why would they claim you are looking at them if your eyes are looking straight ahead ? They can't tell what you are seeing in your peripheral field if your eyes are straight ahead.

Unless your eyes are on the side of your head, you can't be seeing any wider than anyone else. Don't worry about it.

The max humans can see is a 180 degrees arc , although most people see between 160 and 170 degrees.  (+ info)

Does anyone have a link to a general website about breast tumors?

---

My girlfriend just found out she has a tumor in one of her breasts. I'm in a different city than she is right now so I'm trying to find out a little more information about the general size and placement of benign vs. malignant tumors, if there are any size differences. If not, then I'd just like to see what the stages of breast cancer are so that I can be prepared and generally more informed. Thanks.
This site is an excellent source of information:

How accurate are CT Scans for finding brain tumors?

I was just wondering, how accurate are CT Scans at finding brain tumors? I've recently just got a CT Scan and it came back clean. But I was curious what the different would be for an MRI, or a CT Scan with Contrast Fluid?
