Is it possible to damage DNA from single chest CT scan which can lead to cancer later in life? If yes then how long it will take to develop?
Stop worrying: Your dna is being damaged constantly as you go about your business. Your own body, especially your potassium atoms, are radioactive, and you are being bombarded constantly by cosmic rays. Scans are only one of thousands of sources of radiation. You can't avoid it, the exposure you get in a scan is hopefully worth the benefit, and you need keep it in perspective and get on with living your life. ...Read more
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Abnormal pap smear result, chart online says A in "Flag" category w/ HSIL. With title "Pap IG, CT-Ng, rfx HPV ASCU what does this mean? Do I have HPV?
Follow up on this!: It is not entirely clear what this line means but let me break it down for you a bit. HSIL stands for high grade squamous intraepithelial lesion. This is one step before cervical cancer and if that's what the pap said, you need a colposcopy and cervical biopsy. CT usually means chlamydia was negative. rfx HPV means reflex HPV in the event that the pap is ASCUS. HPV is positive for most HSIL. ...Read moreSee 1 more doctor answer
Hi! I have a question about my d dimer levels. It was 278 ng/ml. Is that high? Had other tests that were normal. Ct of lungs, echo, chest xray and cbc
An AFP values of 15 ng ml that remained the same one year later is important? Inicial abdominal eco and ct showed liver hemangioma. Hep C and B neg.
AFP alone is unrelia: Tumor markers like AFP are not useful tests and are often misleading. So these are not recommended to be done. Now that you have had it done, recheck in one year...If it remains unchanged, you can ignore it as an anomaly, nothing of concern. ...Read moreSee 1 more doctor answer
DNA replication: I would go to wikipedia for this. Cannot think of only 3 steps. There are many more. But if you are taking a class I would look it up in the class text book. ...Read more
It's complicated...: Dna tests don't compare every gene-pair in one person with those in another person. Instead, there are many types of tests. The tests look at only some sections of people's dna. One can ask the person doing the test which kind of test it is and how likely it is for various matches to occur. Lots of information is at: http://en.Wikipedia.Org/wiki/dna_profiling. ...Read more
Theoretically.....: It first depends on what what you were sampling to determine the profile (blood versus cheek cells vs semen). Dna profiling examines extremely polymorphic (varying) regions of the genome. If the chemo caused a dna change in a primitive stem cell in your body in one of these locations, it theoretically could affect a dna profile. Fun thought experiment, but super unlikely. ...Read moreSee 1 more doctor answer
Too complex for a: Short answer. Dna provides the code for making proteins that carry out most of the functions in the body. Rna is the step between dna and protein. Briefly, dna is transcribed into rna; RNA is further processed to the right size and content and translated into proteins. Both dna and RNA also have complex regulatory functions. ...Read more

Explain why the accuracy of RNA transcription is not critical as the accuracy of DNA replication?
