Skin Cancer

Skin Cancer

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...

Background:

Malignant melanoma (MM) recognition in whole-slide images (WSIs) is hindered by massive image dimensions and intricate visual features.
Accurate MM detection is crucial for timely clinical diagnosis and treatment planning.

Purpose of the Study:

To develop an automated method for MM recognition in WSIs.
To address the challenges posed by large image sizes and multi-scale pathological features.

Main Methods:

Proposed a novel method (MPMR) utilizing multi-scale features and probability mapping for MM recognition.
Implemented patch-based processing to manage large WSI sizes.
Developed a multi-scale feature fusion architecture incorporating additional branches and shortcut connections.
Enhanced feature extraction for irregular lesions using deformable convolutions and channel attention mechanisms.

Main Results:

The MPMR method demonstrated superior performance compared to existing algorithms.
Generated probability maps effectively visualized MM tissue recognition within WSIs.
The multi-scale feature fusion captured both detailed and semantic information for enriched lesion representation.

Conclusions:

The proposed MPMR method offers a robust solution for automated MM recognition in WSIs.
The approach shows significant potential for practical integration into clinical diagnostic workflows.
Effective handling of multi-scale features and lesion characteristics improves diagnostic accuracy.
