29 year old female 2 head CT scans without contrast within 2 months of one another. What is my cancer risk? I have read "small" or "negligible"

29 year old female 2 head CT scans without contrast within 2 months of one another. What is my cancer risk? I have read "small" or "negligible"

Negligible: Two CT scans will not raise your risk to a measurable level, above your background risk.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

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

Exposure: You should discuss radiation exposure with any doctor ordering CT, X-ray, nuclear medicine or other radiation exposure tests. There is a cumulative effect and these tests should be done only when the need for the information justifies the exposure. ...Read more

Would 6 CT scans early in your 40s increase your cancer risk later in life? If so by how much and how many years later?

Would 6 CT scans early in your 40s increase your cancer risk later in life? If so by how much and how many years later?

Yes: It depends on the type of ct scan. For standard abd/pelvis Ct scan, 6 scans would result in a total effective dose of 84 mSv, resulting in a theoretical increased lifetime cancer risk of 0.559% or 1/179 over baseline. You can calculate this, and more, at xrayrisk. Com. Latency for radiation induced cancer is probably at least 15-20 years. ...Read more

What is the risk of cancer from a CT scan?

What is the risk of cancer from a CT scan?

Extremely low.: The amount of radiation a patient is exposed to with a single computerized tomography (ct) scan is way below the amount required to inflict the necessary dna damage to cause cancer. In fact, studies have proven that a pregnant woman may safely receive a single ct with no negative effects to the fetus (although efforts should still be made to minimize unnecessary exposure). ...Read more

Could first CT scan increases my risk of cancer?

Could first CT scan increases my risk of cancer?

Very slightly: All radiation slightly increases cancer risk. No one knows exactly how much but increased amounts of radiation cause increased risk. You don't say what type of CT scan. According to http://www. Xrayrisk. Com/calculator/calculator. Php a brain CT may cause cancer in 1 out of 8000 while abdominal CT can cause cancer in 1 in 2000. The information obtained is considered worth the risk. See comment: ...Read more

Confusing information regarding CT scans. How dangerous are they? I probably have had 15-20 CT head lifetime, not sure. Cancer risk high????

Confusing information regarding CT scans. How dangerous are they? I probably have had 15-20 CT head lifetime, not sure. Cancer risk high????

Fear mongering: Please forgive my frankness. Getting a CT scan gives you about the same amount of radiation as you'd get from living for three months in Denver rather than Topeka. The increased cancer risk in Denver, if any, isn't measurable. Doctor-bashing is big-money and there's no requirement not to mislead. If there's any suspicion you needed a CT scan, we have to get you one. Don't worry -- not productive. ...Read more

How much does my cancer risk increase after a CT Scan of the head as a teenager?

How much does my cancer risk increase after a CT Scan of the head as a teenager?

Almost no risk: Please see: http://www. Scientificamerican. Com/article/how-much-ct-scans-increase-risk-cancer/
also:
1) CT head exposure is mostly confined to the head, not the whole body.
2) There may be cellular repair at doses as low as CT, limiting cancer rates. (We don't know how much).
3) Whatever the theoretical risk, there must be a good reason to do the CT in the first place. ...Read more

Angry that Doc ordered abd/plv CT scan and did not inform me that there is a slight increase risk of cancer. Scan was unnecessary. What should I do?

Angry that Doc ordered abd/plv CT scan and did not inform me that there is a slight increase risk of cancer. Scan was unnecessary. What should I do?

No worries: No worries. In an individual adult patient, her chance of getting a particular cancer from a couple of CT scans is zero (mathematically rounded, of course). The slight increase in risk shows up in populations studies, meaning there may be one unlucky person out of thousands. For an individual, there is no difference from a couple of scans. If one doesn't like her doctor, then change doctors. ...Read more

Calculated xray risk, 2% risk of cancer from 11 years CT (illness, accidents). Drs told me body healed itself from xray. Upset. Feel mislead. Insight?

Calculated xray risk, 2% risk of cancer from 11 years CT (illness, accidents). Drs told me body healed itself from xray. Upset. Feel mislead. Insight?

XR risk: Using Xrayrisk. Com website? Yes, you are at increased risk for CA but absolute increase in risk remains very low. That 2% is a lifetime risk. Turn it around - There is a 98% risk that you will not develop cancer as a result of accumulated scans. I assume that each of the scans was done for a good reason and was necessary - the benefit outweighed the small increase in risk. ...Read more

Please tell me if a single chest CT scan can lead to cancer? I am worried about cancer risk.

CT scan risk: There are items that can increase the lifetime risk of cancer. A single ct chest scan will increase that risk more than an xray. But if you need the ct chest scan, than the benefits can outweigh the risk. Smoking is a much worse avoidable risk factor for cancer. Also, to decrease cancer risk, eat a healthy diet including fruits and vegetables and reduce red meat. ...Read more

I had one CT angio full body and one full body CT scan last yr in a10 day period. The total exposure was 52 msv. What is my cancer risk? I am 27.

Remote: Excessive radiation carries some risk of causing Cancer but many years later (>10 years). Only doses in excess of 100 msv carry significant risk. In your case, my guess is that, the odds are less than one in thousand individuals. ...Read more

30 y/o healthy male. Over the past ten years I have had several CT scans: 3 of my head as well as a CT myelogram. Is my cancer risk much higher?

30 y/o healthy male. Over the past ten years I have had several CT scans: 3 of my head as well as a CT myelogram. Is my cancer risk much higher?

No: A person's cancer risk is not much higher before or after several CT scans. An individual person's tiny increase in cancer risk is not measurable. Of course, a person should only get x-ray studies if medically needed... to keep one's lifetime radiation exposure lower. ...Read more

I had headaches when I was 15 I had a CT of head was fine then a few months later I fell and hit my head got another CT now scared of cancer risk?

Small increase.: Your absolute risk went up a little but not a lot. The lifetime risk of CA is about 1/1500 for each head scan. This is about 0.35% increase over baseline risk (which is low but never 0%) ...Read more

I have been reading about danger of CT scan and the cancer risk later in life. I had one chest ct. Is it possible to get cancer later from that CT?

Not likely: We are all exposed to radiation all the time in low amounts. Ct scans do expose a person to small amount of radiation, but these tests provide a lot of useful information. It is not likely that you will get cancer, that you were not going to get otherwise, by having one ct. ...Read more

Have received roughly 25msv of radiation from CT scans past three year. Will have no more unless absolutely nessecary! 22yr m vegetarian, eat lots of fruits and veg, what is the risk of cancer? Scared

Less dose than airli: This is a very low dose compared to other risks in our environments. It is less than an airline attendant who makes a couple of transcontinental trips a year. I think we would all be well advised to limit unnecessary radiation but if there is a medical need I would have no problem getting another ct or pet scan. The only exception would be a pregnant woman in first trimester. ...Read more

Child had 2 separate head CT scans as an infant, now healthy 6 year old. How concerned should we be about increased risk of cancer as a child?

Stop worrying...: ... And be effective. The slight increase is real but there is not a thing to do about it, and ct's that get ordered appropriately in children are worth the tiny risk. Plan for your child to have a normal life, teach him/her the social and job skills that tomorrow's competitive world will require, and create a winner rather than a worrier. ...Read more

Lifetime risk: I understand that you are concerned about an increased risk of cancer from the radiation from diagnostic imaging. Although there is an increased risk of developing cancer from anything that produces radiation, the benefits from these studies are likely to be greater than the risks. Go to www. Xrayrisk. Com to calculate your increased risk. ...Read more

Had 6 negative CT scans for a benign lung nodule in my early 40s. Is my risk of cancer increased, by how much and how many years down the road?

Cannot predicy: If after all those CT scans there has benn no change in the finding, then the likelihood it is nothing to worry about. Your risk of cancer is not increased by this nodule or the CT. There are never any guarantees that you won't get cancer. A healthy life style without smoking and the like will certainly be in your favor. Good luck ...Read more

Is it unethical for a doc to order a CT scan but not inform patient of the amount of radiation exposure and slight increase risk of cancer with scan?

Not ethics issue: It is common knowledge that x-ray studies such as regular x-ray films or CT scans do put out a bit of radiation, and that radiation does not noticeably increase "one particular person's risk of cancer, " when added to the radiation risks for cancer she already experiences just by living on planet Earth. Doctors do discuss the risks of getting repeated x-rays, but that is a different situation. ...Read more

No, I don't think: It increase your brain cancer risk at all. Althogh there is more radiation in a CT than a conventional xray, the risk of cancer inducement is very, very small. I don't think you have anything to worry about. ...Read more

What can be done to reduce cancer risk after CT scan (chest). I m worried about thyroid cancer as it is related to chest CT scan.

Don't worry: Hello - the radiation exposure from one ct scan is low. You do not need to worry about thyroid cancer because of a ct. We are exposed to radiation throughout our normal daily routines and when we fly. If you'd like you can limit other exposures. Request pat-downs at security at airports instead of the scanner for example. I don't think you need to do anything, however. ...Read more

What are the chances of getting lung cancer from one chest CT scan? I had one chest CT scan month ago and I m worried about cancer risk.

None!: You cannot get cancer from one routine ct scan. It takes more than dozens of ct scans over a life time, even then it is rare to have this problem. Otherwise we will be foolish doing ct scans on people in order to help them! ...Read more

I'm November, I had 2 CT scans. One was an angiogram with chest, abdo, pelvis. The second was neck, chest, abdo, pelvis. What is my risk of cancer?

Prob not any higher: The risk of cancer from the radiation exposure from the CT scans is not high. We should always limit unnecessary procedures, but if your doctor recommends a scan, usually it is because he/she feels that the potential benefits outweigh the risks. Please don't worry. Take care. ...Read more

Computed Tomography (Definition)

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
