Conclusions
A simple and reliable method of diagnosing normal and cancerous blood by observing a drop allowed to clot and dry on a glass slide is presented. It is suggested that disturbance in the plasma content is the factor which alters the compact pattern of normal blood.
Once the pattern of early cancer is recognized, every effort should be made to locate the malignant lesion and institute prompt therapy.
The test should be repeated at frequent intervals to ascertain results of therapy and to determine the prognosis.
It is hoped that the routine use of this simple method will furnish a clue to the presence of cancer, make possible earlier diagnosis, adequate therapeusis, and achieve a greater percentage of cures.
