This New 10-Minute Test Detects Cancer Early Using Gold Particles

We talk a lot about preventive medicine, especially when it comes to cancer, which includes dietary  and life-style changes like managing stress and reducing environmental toxins. But that's only part of the cancer-combating equation. Early detection is essential, as it increases the chances of successful treatment, and scientists have been developing ways to detect cancer earlier in non-invasive ways—but a new discovery by researchers may be the most important to date.

Now, thanks to these Australian researchers, we have a way to identify cancerous cells using just a 10-minute test and any tissue sample (including a blood sample), according to their new study.

How does it work? All of our healthy cells contain patterns of molecules called methyl groups, which spread across the genome. In cancer cells, these methyl groups appear in dense clusters at certain locations, and when affected cells were put in water, it caused, "DNA fragments to fold into unique three-dimensional nanostructures that could easily be separated by sticking to solid surfaces such as gold," says one of the study authors.

The altered cell structure of the cancer cell found in the sample was drawn to gold particles, changing the color of the cell when they came in contact and allowing scientists to separate the cancer cells from the healthy cells.

So, while the method uses circulating cancer DNA in the blood, similar to a liquid biopsy, this detection method is novel because it's simple, less expensive than other testing methods, and has the potential to pair with a smartphone.

While the test has yet to be done on humans, the study reports 90% accuracy  after testing 200 human cancer samples and healthy DNA. "This unique nano-scaled DNA signature appeared in every type of breast cancer we examined, and in other forms of cancer including prostate, colorectal and lymphoma," the Dr. said in a statement.

The next step is to run large-scale clinical trials to determine just how early cancer can be detected. The researchers are already assessing whether other bodily fluids could be tested to detect cancers. These are cutting-edge discoveries, and we are standing by for what happens next.

Women reveal the reasons they reject a preventive drug for breast cancer

Only around a fifth of women at higher risk of developing breast cancer think they need to take a drug proven to help prevent the disease, according to new research.

Around 72% said they were worried about the long-term effects of tamoxifen and 57% believed that the drug would give them unpleasant side-effects.

The researchers asked more than 400 healthy women at a higher-risk of breast cancer, from 20 centres across England, whether they thought they needed to take tamoxifen and their concerns about medication.

They discovered that almost a third (29%) of the women thought doctors prescribed too many medicines, and more than a third (35%) thought doctors would prescribe fewer drugs if they had more time. Around a quarter (24%) of the women had experienced bad reactions to medicines in the past.

Almost a quarter (24%) of the women thought people on medication should take regular breaks from the drugs; 23% said they were very sensitive to medicines and 17% believed natural remedies were safer than medicines.

In a follow-up questionnaire, answered by 250 of the women, researchers found that fewer than 15 per cent were taking tamoxifen despite having discussed preventive therapy with a healthcare professional. Women who believed the medication was less necessary and had more concerns about its use were less likely to be taking tamoxifen at follow-up.

Lead author said: "Women in our study were rightfully considering the potential harms and benefits of using preventive therapy. But some beliefs about the use of medicine were very negative. This appears to be putting some women off tamoxifen, despite its proven ability to help prevent breast cancer in the long term.

"We need to make sure health care professionals are adequately equipped to discuss the potential benefits and harms of preventive treatment with their patients so that women are well informed before deciding whether or not to take a drug."

A Dr. said: "It's understandable that women considering taking a new medicine might have some concerns and that, for some, it won't be the right option. There are some potential side effects with tamoxifen, and other medications that can help prevent cancer, but it's vital that they have all the information, so they can make the best choice for them. If women in this situation have any questions or want more information, they should discuss with doctors and nurses to know all the prod and cons of taking tamoxifen.
