Comparative genomic hybridization (CGH) analysis provides comprehensive information about relative chromosomal losses and gains in malignant tumors in vitro. Using the CGH technique, chromosomal aberrations in both the primary tumor and its metastatic lymph nodes was detected in patients with esophageal squamous cell carcinoma (ESCC).

Oral squamous cell carcinoma is a deadly cancer that, even when treated successfully, often leaves patients permanently disfigured. Other than radical surgery, there are few known treatments.

Inherent gender differences - instead of more sun exposure - may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center.
