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

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

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

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

I am worried about my cancer risk as I had one CT scan to rule out lymphoma. I am 30yr and healthy. I am not able to sleep because of fear from ct.

VERY low risk: If I understand your question correctly, you are concerned about developing cancer because you had a ct scan. You should not worry, having one ct scan has essentially no effect on your future risk of developing cancer. ...Read more

Had 2 head ct scans in 2 years. Does this increase my future brain cancer risk even more since they were done so close together?

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 had a ct 5 days ago and 3 x-rays today pelvis/abdomen flank pain all normal. Dr wants another ct with and w/o contrast done. Is this a cancer risk?

Low risk: It does seem to be excessive the risks should be counted through out your lifetime. If you didn't have any other studies requiring X-ray radiation you'd be fine. But this seems really excessive when ultrasound or MRI can be used to get more information. Try suggesting these non ionizing radiation studies ...Read more

What are the chances of getting cancer from a CT scan with and without contrast in your early 20's if you are female?

I had 2 full body CT scans within 2 weeks, with a combined exposure of 53 mSv (I asked the radiologist). 28 yo/female. Will I get cancer?

Very unlikely: There is no significant risk of developing Cancer just because of getting 2 CT scans. The CT scan related radiation poses minimal risk, as most medical use of X-rays has minimal risk unless you get exposure over several hundred mSvs. So just try to forget about it. eat healthy and live a healthy life style as Cancer does develiop in otherwise healthy people (one in 5 females during a life time will ...Read more

30 year old female having sever anxiety over my first and only CT scan for a rib injury, terrified one scan is going to give me cancer in a few years?

The theoretical risk: Of any procedure or treatment should always be weighed against the benefit. In your case, the theoretical risk of developing a radiation induced cancer from one chest CT is slight, about 0.09% over your baseline risk. To put that in perspective, you have about a 10x higher lifetime risk of dying in a motor vehicle accident. Yet few people worry very much about getting in their car. ...Read more

Sacro illiacal hyperdens bone 150 mm 120 mm possible hemangioom severe pelvic pain- seen on CT after I fell off stair - cancer? 30 female

No cancer: Common to have bone or even muscle pain if one suffers a fall probably landing on the sacroiliac region. Often one has disruption of a tendon from its pelvic attachment such as the hamstrings from ischial tuberosity with hematoma, not hemangioma of bone. Warm baths will help subside the condition. Cancer is never the result of such trauma. ...Read more

I'm 17 female I've dyed my hair a lot and I have had 3 CT scans I'm scared that I'm gonna get brain cancer?

Increased Risk: No good data on whether hair dye increases cancer risk; best answer: almost certainly not. CT scans are another story. There is increased risk of radiation-caused cancer from CT scans. The risk is very low but not zero. A CT is a highly sophisticated Xray which uses the same type of radiation. Doctors have begun to move away from CT where possible, but sometimes CT is the only imaging study ...Read more

If any question, you should have MRI of brain without contrast. Radiologist can then add contrast study as needed. ...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
