Basically, the procedure should include:
1) A full explanation of the procedure. After, you will be asked to sign a consent form allowing them to do the procedure. Don't be afraid to ask any questions you may have before signing.
2) Preparing the area with antiseptic to prevent infection. Then, sterile drapes around the area to give a sterile work area.
3) Local anesthesia injection to numb the area.
4) Biopsy performed.
5) Area cleaned and either a Bandaid or Sterile-Strips applied.
6) Post-procedure instructions. This includes any possible restrictions activities, what to take if you have any pain, sign of any infection to watch out for, etc.
Bottom, line: every effort should be made to make the experience as painless and as easy for you as possible. I've had many patients tell me they felt nothing. Again, this depends on the area. I mostly do breast and lymph node biopsies these days. Biopsies of organs or tumors in the deeper areas like the chest, abdomen, or pelvis are similar, but a little more involved and could be slightly more uncomfortable, but should not be terrible.
Modern day CT scanners incorporate methods to reduce radiation exposure to the patient while still providing good quality images for the radiologist to interpret.
Regarding cancer, you first have to start with the fact that cancer is a common disease and it is estimated that about 42% of a given population will develop cancer in their lifetime, a shocking figure I believe.
For women, the lifetime cancer risk without any radiation exposure is about 37.5%. The exposure you received depends on the machine, the type of scan, and your body (heavier patients require more radiation to penetrate the body).
An average abdominal CT using dose reduction techniques results is an exposure of about 6 millisieverts, abbreviated 6 mSv.
A CT examination with an effective dose of 10 millisieverts (abbreviated mSv; 1 mSv = 1 mGy in the case of x-rays.) may be associated with an increase in the possibility of fatal cancer of approximately 1 chance in 2000. This increase in the possibility of a fatal cancer from radiation can be compared to the natural incidence of fatal cancer in the U.S. population, about 1 chance in 5 (equal to 400 chances in 2000). In other words, for any one person the risk of radiation-induced cancer is much smaller than the natural risk of cancer. If you combine the natural risk of a fatal cancer and the estimated risk from a 10 mSv CT scan, the total risk may increase from 400 chances in 2000 to 401 chances in 2000.
As with many things in medicine, you have to weigh the risks vs. benefits.
Bottom line, your increased risk of cancer from the two scans is likely negligible.
Hope this helps!
Guessing, I would say bronchitis or other viral disease.
My son is working in the hospital as a radiologist. Will the waves from the machines cause him any harm?
Every hospital has an RSO, or Radiation Safety Officer, whose job is to not only review the exposure reports, but to make sure an individual is not getting exposed to significant amounts of radiation. Also, the RSO works with a Radiation Physicist to make sure all the devices which can produce radiation are exposing patients and staff to the lowest levels possible.
Depending on the particular scan ordered by the requesting doctor, the patient may get X-ray contrast injected in a vein in the arm or hand via an IV line. This highlights blood vessels and can aid in diagnosis. Some scans of the abdomen also require the patient to drink some contrast to highlight the stomach and gastrointestinal tract. It is an easy exam for the patient as they basically just need to lay still for several minutes.
With regards to the term "pneumonitis," it refers to inflammation of lung tissue and generally is used to describe findings that are non-infectious, caused most often by an allergic response, as opposed to "pneumonia," which would be caused by an infection with some microorganism.

My son suffered from severe pneumonia 5 months back. Will the X-rays that were taken cause him harm in the long run?
Also, since the CT uses a computer to reconstruct the images, the radiologist can manipulate the images in many ways, including taking density measurements of any abnormality (which can help figure out what it is), measure structures, change factors to be able to look at bones or soft tissue, and other manipulation.
Bottom line is that a CT scan can provide a much more detailed look inside the body than a regular X-ray and it is an amazing tool to help with diagnosis.
I hope this helped!
