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

My husband has a cancerous tumor on his neck. The doctor said it either started as a leision or HPV virus. Can i be at risk for hpv. ?

My husband  has a cancerous tumor on his neck. The doctor said it either started  as a leision or HPV virus. Can i be at risk for hpv. ?

Possibly: If in fact your husband has had hpv (which appears to be in question) it is also possible that he transmitted it to you. I suspect, however, that if you have had pelvic exams with pap smears done during the years of your marriage and they have not revealed changes compatible with hpv infection, then you are free of disease. It would be advisable to see your ob/gyn doctor. Good luck. ...Read more

I read mmtv-like virus is highly expressed in breast tumors so it's likely that this viruses causes breast cancer. How can I see if I have this virus?

I read mmtv-like virus is highly expressed in breast tumors so it's likely that this viruses causes breast cancer. How can I see if I have this virus?

It's not true: This is an internet scare story based on some old work in 2004 that didn't pan out. The claim was simply that DNA sequences resembled those found in the familiar mouse tumor. This doesn't stop people from writing misleading articles on the internet. ("Your doctor isn't telling you the truth!") Nobody's even grown the virus from human breast cancer samples. ...Read more

I had a brain MRI completed to identify any organic damage, viruses, and endocrine tumors, who is the most qualified DR to request for interpretation?

I had a brain MRI completed to identify any organic damage, viruses, and endocrine tumors, who is the most qualified DR to request for interpretation?

Neuroradiologist: Hi. You needn't worry. Whichever doctor ordered it, it will be read by a qualified radiologist. You don't need to request anything. Of course you can't see a virus with anything less than an electron microscope, but you mean lesions that could be caused by viruses. Good luck! ...Read more

Can virus cause persistant come-and-go ha, slightly stiff neck, general lethargy? Otherwise healthy woman..Sound like brain tumor? No neuro symptoms

Virus and HAs: Many viruses can cause the symptoms you describe. In most cases, the symptoms are self limited and will resolve. If not, consult your doctor. There is no evidence to worry about a brain tumor; while a stiff neck can be associated with a viral meningitis, most of these are self limited and will resolve. Unless your symptoms persist or worsen, there is no need for alarm. ...Read more

What happens if cytotoxic t cells destroy cancer and viruses, then why do humans still get these diseases and tumours?

What happens if cytotoxic t cells destroy cancer and viruses, then why do humans still get these diseases and tumours?

Great question!: This is one of the "holy grails" of cancer immunology research. Cytotoxic t cells are suppressed by other t cells, and some cancers and viruses create molecules that increase this suppression of cytotoxic t cells. There's also the problem of tolerance; our immune systems don't work against ourselves (usually), and cancer and viruses involve normal cells that are protected from immune attack. ...Read more

If tumor markers are consistently rising does it mean tamoxifen isn't working? My ca27-29 went from the 20's to 48 to 52 and now 66 since october.

If tumor markers are consistently rising does it mean tamoxifen isn't working?  My ca27-29 went from the 20's to 48 to 52 and now 66 since october.

Setting?: Are you taking it after curative surgery (adjuvant) or to control metastatic disease? Markers can be confusing. I have to say the progressive elevation of your 27.29 is suspicious but i'm taking it out of the context of your clinical situation. I'm sure your oncologist will gladly sit down with you and explain its meaning and what he/she has in mind for next. ...Read more
