One thing I would not do is push for a mammogram. If you are not on any birth control pills, a simple pregnancy test will detect cancer. It is over 92% accurate, so I would take it twice to make sure. If it is cancer, the HCG levels will show up in the pregnacy test indicating pregnancy. Negative indicates no cancer. If it should show up positive, then I would go on to take the Navarro Test to see what my score was. Anything over 50 indicates cancer. This also works by showing the HCG levels in your urine. In the meantime, should the pregnacy test be positive, you could implement alternative measures to address the cancer. By chance is that one breast growing larger than the other? As Lolite states, it could be fibrocystic breast disease, or it could even be mastitis. I would follow her suggestions and to that add colloidal silver. Colloidal silver will eliminate any possible infections.
However, I would never opt for a mammogram. The intense radiation that your body withstands during this procedure paves the way to future cancer.
