It takes years for a mass or tumor to grow to the size when it can be seen by a mammogram.  That's how long it takes for the cells of an average growing cancer to grow to about the size of a pea (about 1 cm) and most often does not appear in a mammogram if any smaller than this.

​Active Cancer Cells Can Double in Number Every 90 Days

The hypothetical chart above is a representative of an average growth pattern of the typical slow growing breast tumor. Most doctors agree and even tell their breast cancer patients that they have had the growth for 8 or 10 years.


Mammograms are a good tool for determining the exact location of a developed tumor, but it is not an early warning system, which some women assume that it is. “Early” is a relative term, so if a mammogram can see it in the 8th year, it is earlier than the 10th year, but in any case, even the 7th year may be too late to change the outcome. The real danger of breast cancer is whether or not it has spread to a vital organ. If it is going to spread, it has had many years to do so. Women deserve earlier detection, and this is it. Thermography can see the blood supply that feeds a tumor in its infancy, and the only way to detect it in that stage is to establish a thermographic baseline and monitor every year for the real early signs!   Thermography can totally change a person’s health history in advance.
