radiographer said he did see something, but...

You are right four months is too long. Cancerous tumors can grow fast!!! There is a new breast ultra sound call Sonicine. Not only does Sonocine help to avoid unneccessary radiation to breast tissue, SonoCine's clinical trials demonstrated that it found more and smaller cancers than mammography without incurring excessive false positive or biopsies.

Also, depending on where you live, digital breast tomosynthesis and dedicated breast CT are available. They overcomes the limitations of the conventional mammography. The problem with mammograms is that 3D anatomical information is projected into a 2D image plane, limiting the ability to detect certain cancers.

You can also ask for a breast MRI. It is by far more sensitive than a mammogram.

In the meanwhile,take note of the risk factors for breast cancer. If it is malignant you don't want to feed it with foods like meat, dairy, alcohol and sugar. You'll want to stick with an alkaline diet. Also. check out www.breascancerchoices (dot) org. You'll find lots of great info there.
