(tl;dw for the video: it's about the dramatically improved detection of breast cancer particularly in dense breast tissue (where mammographies often fail to visibly differentiate tumors) by injecting a radiotracer and using small gamma detectors that can fit closely around the breast.)

There's also breast thermography.

And another technique I couldn't find a description of but I read about a while ago, where the breast temperature is altered first. Since tumors have greater blood supply, it makes breast thermography (or something like it... I forget the exact detection method) even more accurate in detecting cancer, since a tumor with greater blood supply will return to normal temperature faster than the surrounding tissue.

Breast thermography appears to be mostly quackery
