Airport scanners do not detect cancer but can identify scar tissue
While airport body scanners do not detect cancer, they can identify scar tissue or similar irregularities. The scanners have been known to pick up breast prostheses, requiring additional screening, such as a pat-down or the use of a handheld security device. This has resulted in insensitive treatment and distress for travellers, particularly those who have undergone a mastectomy.
The risk of cancer from airport scanners is exceedingly small. Although the scanners do not detect cancer, they can expose passengers to low doses of radiation. The exposure is concentrated in the skin and superficial tissues, and there is currently no accurate model for understanding the relationship between skin exposure and the risk of skin cancer.
Several groups have developed models to estimate the risk of cancer following exposure to ionizing radiation, and studies have estimated that for every 2 million girls who travel one round trip per week, one additional breast cancer case could occur from these scans over their lifetime. However, this risk needs to be balanced against the benefits of improved national security and safety.
While the TSA has implemented measures to ensure passenger privacy, such as blurring facial images and separating security personnel from passengers, the scanners' capacity to generate detailed images of passengers' bodies has raised concerns. The TSA has made it impossible for scanners deployed in airports to save or export images, addressing privacy concerns.
In conclusion, airport scanners do not detect cancer but can identify scar tissue and other irregularities. The risk of cancer from these scanners is considered very low, and the focus is on balancing security benefits with passenger privacy and sensitivity.

Backscatter x-rays from scans are concentrated in breast tissue
While airport body scanners cannot detect cancer, the backscatter X-rays they emit are concentrated in the superficial tissues, primarily the skin, and breast tissue. This means that the exposure from these scans can be used to accurately predict breast cancer risk.
Backscatter X-ray technology is based on the Compton scattering effect of X-rays, a form of ionizing radiation. Unlike traditional X-ray machines, which rely on the transmission of X-rays through the object, backscatter X-ray detects the radiation that reflects from the target and forms an image. This technology is good for imaging organic material and is particularly useful for security purposes as it can detect items such as plastic explosives, drugs, and non-metallic weapons that may be hidden under clothing.
The dose of ionizing radiation emitted by backscatter X-ray scans is considered exceedingly low, and the potential for harm is thought to be trivial. However, it is important to note that even very low doses of radiation can cause biological damage, and at moderate doses, cells can be permanently changed, potentially becoming cancerous. While the risk of cancer from airport scanners is exceedingly small, it is not zero, and with 750 million passenger enplanements a year, even a small risk per person could result in a significant number of cancers.
The use of backscatter X-ray scanners has raised concerns about privacy and potential health risks. The detailed images created by these scanners have been likened to virtual strip searches, and some groups have protested their use, arguing that they violate personal rights and privacy laws. Additionally, there have been concerns about the accuracy of the claimed effective dose of radiation, with some professors arguing that the dose is higher than claimed as it is mostly absorbed in the skin and tissues immediately underneath.

Exposure risk is proportional to dose, with no exposure threshold
While airport body scanners do not detect cancer, they can identify foreign items worn on the body, including breast prostheses. This means that women who have had a mastectomy may be subjected to insensitive treatment during security screenings, including being asked to remove their prosthesis or undergo a pat-down, which can be distressing and humiliating. This has prompted calls for improved training for security staff to ensure they interact with these passengers in a sensitive manner.
It is important to note that the radiation exposure from airport body scanners is minimal and equivalent to a short cellphone call. The risk associated with this exposure is typically assumed to follow a ""linear no-threshold" model, which suggests that every exposure carries some risk, no matter how small. However, this assumption may not be entirely accurate, as there is no accepted mathematical model for understanding the relationship between skin exposure and the risk of skin cancer.
The "linear no-threshold" model implies that the exposure risk is directly proportional to the dose, with no safe threshold. While this model is widely accepted, it is challenging to accurately estimate the risk associated with extremely low exposures from airport scans. The exposure from these scans is primarily concentrated in the superficial tissues, particularly the skin, and the distribution of exposure is different from what is assumed in the available cancer risk estimation models.
Although the risk associated with airport body scanners is considered exceedingly small, it is essential to balance the risks and benefits of their use. The deployment of these scanners should be justified by their ability to improve national security and safety. While the scanners have raised concerns about privacy and sensitivity, measures have been implemented to address these issues, such as blurring faces in scanned images and separating security personnel from passengers during screening.

Scanners can detect foreign items worn under clothing
Airport scanners are designed to detect foreign items worn on the body, under clothing. These scanners can identify various items, including prosthetics, catheters, and piercings. While they are not designed to detect cancer, they can identify scar tissue or similar irregularities, which may cause certain areas of the body to light up on the scan. This has been observed to occur in individuals who have undergone breast surgeries or radiation treatments.
In 2018, the Australian government mandated the use of full-body scanners in airports across the country. These scanners have been reported to detect breast prostheses worn by individuals who have had mastectomies. This has resulted in additional screening procedures, such as pat-downs or the use of handheld security devices, which can be distressing and insensitive for travellers. To address this issue, organisations like the Breast Cancer Network Australia (BCNA) have called for improved training for security staff at airports.
The sensitivity of airport scanners can be attributed to their advanced technology. While the scanners can generate detailed images that reveal intimate body parts, privacy measures have been implemented. These include blurring faces, using software to make images less provocative, and separating security personnel from passengers during screening. Additionally, measures have been put in place to prevent the storage and export of scanned images, ensuring passenger privacy.
It is important to note that while airport scanners can detect foreign items under clothing, their primary purpose is to enhance security and safeguard passengers. The use of these scanners aims to balance the risks and benefits, ensuring national security without compromising passenger safety. However, it is crucial for security agents to demonstrate compassion and sensitivity during the screening process, especially when interacting with individuals who may have medical conditions or special needs.
In summary, airport scanners are capable of detecting foreign items worn under clothing, including prosthetics and scar tissue. While this technology enhances security, it also underscores the importance of sensitivity and privacy in the screening process, particularly for individuals with unique medical circumstances.

Insensitive treatment of cancer survivors during security screening
Airport scanners do not detect cancer, but they can detect scar tissue, which may cause distress to cancer survivors. In 2021, a woman who had undergone a bilateral mastectomy with implant reconstruction and radiation therapy experienced her right breast lighting up during a security scan, requiring a pat-down. This experience is not uncommon for women who have had breast surgeries or radiation treatments. While the TSA has implemented measures to protect passenger privacy, such as blurring facial images and separating security personnel from passengers, the process can still be insensitive to cancer survivors, particularly those wearing breast prostheses after mastectomies.
In Australia, the government mandated in 2018 that airports switch from metal detector scanners to full-body scanners, which detect foreign items worn on the body, including breast prostheses. This has resulted in insensitive treatment for women wearing prostheses, including public pat-downs and being asked to remove their prostheses in private rooms. Breast Cancer Network Australia (BCNA) has received complaints from distressed women and has called on airports to ensure staff are trained to interact sensitively with travellers wearing breast prostheses.
The risk of cancer from airport scanners is exceedingly small, but it is important to balance risks and benefits. While the scanners do not detect cancer, they can detect scar tissue and foreign items, which may cause distress and insensitivity to cancer survivors, particularly those wearing breast prostheses.
To address these concerns, some have suggested that airports provide training for security staff on interacting sensitively with travellers wearing breast prostheses. Additionally, it is important to consider the benefits of the scanners in improving national security and safety. While the risk of cancer from airport scanners is small, it is not non-existent, and the available models for estimating cancer risk from these scans are inaccurate. Therefore, it is crucial to weigh the benefits of the scanners against the potential risks and distress caused to passengers, especially cancer survivors.
Furthermore, it is essential to recognise the psychological impact of cancer screening on individuals. While screening can provide a sense of empowerment and control, it can also lead to excessive treatment for slow-growing or non-threatening cancers. This highlights the need for caution and comprehensive understanding when interpreting screening results to avoid unnecessary harm.
