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

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

Not w/o Pathologist: Regardless of the method of biopsy, the only way to DX cancer is to look under the microscope. There are "frozen sections" that can be performed by pathologists within minutes of a biopsy; however, this is not as accurate as staining the tissue (overnight) and compromises our tissue sample. The waiting is the hardest part, no doubt--most often, we can get the results the next day. Hang in there! ...Read more

Is it always necessary to carry out a biopsy on lymphoid hyperplasia or is endoscopic examination and MRI enough to decide that it is benign?

Is it always necessary to carry out a biopsy on lymphoid hyperplasia or is endoscopic examination and MRI enough to decide that it is benign?

Lymph node BX: we need the biopsy to tell the nature of the lymph node. particularly if it is more than 1 cm in diameter.less than 1cm is usually benign.CT/PET could be used to detect the hypermetabolic activities of the lymphnode (significannt) or no hypermetabolic ( beign) If the lymph node is diffucult to reach and 1cm or less CT/PET in proper clinic setting may be enough.and no need for BX ...Read more

Can a gastroenterologist really be sure that a 1.6 CM diameter mass is cancer at the time of an EUS? Is it best to wait for biopsy report results?

Can a gastroenterologist really be sure that a 1.6 CM diameter mass is cancer at the time of an EUS? Is it best to wait for biopsy report results?

Yes, it is a must: Nothing further will be done till the biopsy results clearly confim the diagnosis of cancer. Nobody will dare to give you chemotherapy without a biopsy confirmed diagnosis of Cancer. ...Read more

Which procedure is done to see if a tumor is malignant?

Where is the tumor?: Skin tumors can be removed and examined by a pathologist. An intraocular tumor requires ultrasounds, serial exams, angiograms, etc. Sometimes, the wall of the eye can be removed. Tumors inside the body require techniques unique to the location. ...Read more

Can a biopsy be done when there is no existence of a mass, lesion or tumor? Just how does a doctor locate the area to biopsy in this situation?

Need more info: Why is a biopsy needed? What tissue is being biopsied? If the biopsy is of skin for a systemic disorder, like amyloid, vasculitis,and lupus, biopsy from a random site may suffice. ...Read more

Not likely: An ultrasound is quite accurate in that assessment when combined with physical exam and site of origin. Is lipoma in the breast? ...Read more

Oncology: Would it be prudent for a surgeon to remove a benign tumor (if it was) of the pancreas when there is a family history of pc?

Oncology: Would it be prudent for a surgeon to remove a benign tumor (if it was) of the pancreas when there is a family history of pc?

Ask the surgeon: I guess the question is 'is there an association between benign tumor and later malignant pancreatic cancer'. But how do you know its benign? In any case, putting the question directly to your surgical consult, and checking the answer with your own practitioner is a good idea. ...Read more

Can a pet scan tell if a tumor is malignant? I know that pet scans can find tumors, but can they tell if a tumor is malignant? Or does a biopsy always have to be done to tell that?

Can a pet scan tell if a tumor is malignant? I know that pet scans can find tumors, but can they tell if a tumor is malignant? Or does a biopsy always have to be done to tell that?

No, usually biopsy: Pet scans detect increased metabolism or consumption of some chemical, usually glucose. Many different diseases can use extra glucose - infection, healing after surgery, tumors (benign and malignant). If no exact diagnosis is known, the pet is positive and the pet scan and anatomy scans like ct do not look like something benign or easily treatable (infection), biopsy is usually performed. ...Read more

If the only way to know if moles or lesions are cancerous is to take a biopsy, what's the purpose of a screening? What if a doctor suspects a mole is normal when it's not? Would it be quick to change?

If the only way to know if moles or lesions are cancerous is to take a biopsy, what's the purpose of a screening? What if a doctor suspects a mole is normal when it's not? Would it be quick to change?

Screening: identifies moles and other lesions with suspicious features that might require biopsy. If a mole has benign features, the overwhelming probability is that it is benign, and biopsy would not be necessary. ...Read more

Can a doctor tell if the cyst or a tumor is malignant by performing a ultrasound?

Can a doctor tell if the cyst or a tumor is malignant by performing a ultrasound?

See answer: A cyst is defined as simple and hence benign if it is sharply demarcated, has no internal echogenicity and has good thru transmission of sound. If the walls are thicker, vascular, nodular, have colorflow or there is internal echogenicity in the “cystic lesion” it isn’t a simple cyst – and either follow-up or additional imaging should be considered to deliniate, based on your drs. Assessment in th. ...Read more

Who's responsibility is it to diagnose a biopsied piece of skin, for cancer, the lab, or the dermatologist who will perform the excision?

Depends: In most cases, the biopsied specimen is sent to a pathologist who makes the diagnosis. However in the case of Mohs surgeons, they also act as the pathologist during the procedure. Many Mohs surgeons will also work together with a pathologist during more difficult cases. ...Read more

What sort of testing is done to see if a tumor is malignant?

What sort of testing is done to see if a tumor is malignant?

Pathological exam: A biopsy to remove a portion or the entire tumor is performed to allow the pathologist to examine the tissue under the microscope using special stains to help assess features to make a diagnosis not only of malignancy but also the type and potential behavior of the tumor. Ancillary tests like flow cytometry, gene rearrangement test for monoclonality, presence of associated tumor markers also help. ...Read more

Is it necessary to be in empty stomach before any type of scan??? Is it a must to be in full bladder condition for a scan?? Thank you

Is it necessary to be in empty stomach before any type of scan??? Is it a must to be in full bladder condition for a scan?? Thank you

Depends on scan: If you are referring to having an ultrasound, then yes, most abdominal ultrasounds require that the stomach be empty and the bladder full, but this also depends on what organ or area is being imaged. For CT or MRI scans, bladder fullness is not necessary unless looking specifically at the bladder or kidneys, and then oral contrast may be ordered. For nuclear medicine studies, it depends on type ...Read more

Biopsy (Definition)

Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...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
