Blood tests are the latest tool in cancer treatment. By taking blood, scientists can detect changes in DNA that can help to assess the presence of cancer cells in the body.
A blood test with the ability to detect five different forms of cancer by looking for abnormal DNA signatures may be close to becoming a reality.
Researchers were able to identify womb, lung, stomach, colon and breast tumours from normal tissue by the DNA signature around the gene ZNF 154.
There is hope that the potential of this diagnostic technique will lead to earlier diagnosis in people resulting in a higher survival rate.
The research has been carried out by the National Human Genome Research Institutes in the US and published by the Journal of Molecular Diagnostics.
An exciting development in chemotherapy drug delivery means that targeting tumours will soon be easier.
Scientists have found a way to reduce the necessary dose of an existing chemo drug by making sure the full amount of the drug reaches the tumour rather than being partially destroyed as it travels through the body. “That means we can use 50 times less of the drug and still get the same results – more effective treatment with fewer and milder side effects.”

A genomics company is developing technology that could spot cancer signs in healthy people from as a little as a few drops of blood.
Although others have succeeded in creating blood tests to detect tumour relapses or cancer progression, spotting cancer signs in healthy bodies is the holy grail.

It’s early days, but researchers are making great strides in the search for alternatives to chemo.
The latest study, led by scientists from the MD Anderson Cancer Center, has found that some people with the most common kind of leukaemia – chronic lymphocytic leukaemia – did better with an anticancer drug called ibrutinib than those who were given chemo.
