Ethanol ablation is a minimally invasive medical procedure that involves the injection of ethanol into a tumor or abnormal tissue to induce necrosis and shrinkage. It is commonly used for treating liver tumors, thyroid nodules, and certain types of cysts, offering an alternative to surgical removal with fewer complications and quicker recovery times.

A tumor is an abnormal mass of tissue that results from excessive cell division, which can be benign or malignant. Malignant tumors, also known as cancers, have the potential to invade neighboring tissues and spread throughout the body, posing significant health risks.

Abnormal tissue

Necrosis is the premature death of cells in living tissue caused by external factors such as trauma, infection, or toxins, resulting in unregulated digestion of cell components. Unlike apoptosis, necrosis often triggers an inflammatory response due to the release of intracellular contents into the surrounding tissue.

Shrinkage is a statistical technique used to improve the estimation accuracy of parameters by introducing a penalty or constraint, often to avoid overfitting in models with many predictors. It is particularly useful in high-dimensional data settings, where traditional methods may fail to provide reliable estimates due to multicollinearity or limited sample sizes.

Liver Tumors

Thyroid nodules are growths within the thyroid gland that are typically benign but can sometimes indicate thyroid cancer. Evaluation often involves ultrasound imaging and fine-needle aspiration biopsy to determine the nature of the nodule and appropriate management steps.

Thyroid Nodules

Cysts are closed sac-like structures that can be filled with liquid, semisolid, or gaseous material, not resembling normal body structures. They can develop in any part of the body and vary in size, often requiring medical attention if they cause symptoms or complications.
