Second Opinion (Cancer Diagnosis) Expert Witness

PDF Print E-mail

Patients are advised to always get a second opinion after getting an initial diagnosis in order to ensure that no errors or mistakes were made. In order to ensure that they are getting a valid diagnosis and prognosis, patients should seek another opinion from an unbiased medical professional who is not related to the first one.

Understanding cancer growth and delay in diagnosis for jury appeal

Cancer grows in all directions; in three dimensions. When a chest x-ray shows a tumor, the report says “2x4 centimeters”, but that is only the two dimensional “view”. When the pathology report says “2x4 centimeters” or “2x4x3 centimeters” the jury’s mind does not calculate the volume or change in volume over time. Growth is the three dimensional volume change, and is most impressive.

One can often identify by evidence or opinion, the three dimensions of the tumor at its various stages of growth. This can be mathematically calculated into volume:

If a square shape changes from 2x2x2 centimeters to only 3x3x3 centimeters, the volume grows from 8 cubic centimeters to 27 cubic centimeters, more than three times the volume, “not just” 2x2x2 to 3x3x3.

From 2x2x2 to 4x4x4 is eight times the volume (8 cubic centimeters to 64 cubic centimeters). Spheres can also be simply calculated, but the volume of irregular shapes is measured using calculus. Any competent mathematician can perform this computation for you. Never rely on two or three dimensional tumor sizes. Always convert those to volume and volume growth for the correct size and jury appeal.
