Skin Cancer

4.3K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Area of Science:

  • Dermatology
  • Medical Imaging
  • Computer Science

Background:

  • Malignant melanoma is an aggressive skin cancer, emphasizing the need for early detection.
  • Computer-aided diagnosis (CAD) systems offer a promising approach for automated skin lesion analysis.

Purpose of the Study:

  • To develop an integrated CAD framework for rapid and accurate detection of malignant melanoma in dermoscopy images.
  • To classify melanocytic skin lesions as either melanoma or nevus.

Main Methods:

  • Image pre-processing using median and bottom-hat filtering for noise and artifact reduction.
  • Feature extraction via Histogram of Oriented Gradient (HOG) and Local Binary Patterns (LBP) descriptors.
  • Classification using Support Vector Machine (SVM), k-Nearest Neighbors (kNN), and Gentle AdaBoost (GAB) models.

Main Results:

  • The proposed CAD framework demonstrated competitive or superior performance compared to state-of-the-art methods.
  • Achieved high diagnostic metrics: 94% accuracy, 92% specificity, and 100% sensitivity on the MED-NODEE dataset.
  • 10-fold cross-validation confirmed the framework's robustness.

Conclusions:

  • The integrated CAD framework provides an effective tool for the accurate diagnosis of melanoma from dermoscopy images.
  • Early detection and classification of skin lesions can be significantly improved with advanced computational methods.
