The vast majority of cancer deaths occur due to the spread of cancer from one organ to another, which can happen either through the blood or the lymphatic system. However, it can be tricky to detect this early enough. Researchers at Tohoku University have developed a new method that would allow doctors to detect cancers in the lymph nodes while they are still small, before they travel to other parts of the body. This can greatly increase the chances of a successful treatment.
There aren’t many imaging techniques that can detect tumors in lymph nodes before they grow too large, especially in smaller nodes. Biopsies of lymph nodes is a possible option, but it can often give false negative results. So the team wanted to come up with a new method that would accurately detect the earliest stages of a cancer moving to another part of the body, using a technique called x-ray microcomputed tomography (micro-CT).
The team tested their new method on mice with breast cancer
