The defining moment in the classification of a tumor as benign or malignant lies in the tumor cells ability to breach the basement membrane.
The majority of the difference between benign and malignant tissue lies in the lipid (1735 cm−1) and Amide I/II (1624, 1570, 1516 cm−1) regions of the spectra, although there are also important contributions from a protein band (1477 cm−1), νasPO2− (1230 cm−1), RNA/carbohydrate (1168 cm−1), and phosphorylated proteins (968 cm−1).
A comparison of the completeness of ascertainment achieved in recent years by each source of data showed that more than 98% of the serious cases (neoplasms that were malignant and/or lay within the craniovertebral canal) could have been identified using a combination of Hospital Activity Analysis (HAA) and cancer registration records, and more than 95% using HAA and death records.

This phenomenon was seen especially in cancer cell groups inside vessels and in addition on the entire surface of shed single cells, lying in malignant ducts.
Cutoff values for differentiating between benign and malignant tissue vary among different malignancies, often lying between 2 and 3, but this may be variable for different types of tumour.
The results from the cross-validation correspond with the results from the clustering, PCA and Student's t-test, showing that the major differences lie between normal and malignant tissues rather than between the two zones.
