Tumorengroei

Tumorengroei refers to the uncontrolled and abnormal proliferation of cells within the body, leading to the formation of a tumor. This process is a hallmark of cancer, although not all tumors are malignant. Tumors can be classified as benign or malignant. Benign tumors are localized, do not spread to other parts of the body, and are generally not life-threatening. Malignant tumors, or cancers, are invasive and have the ability to metastasize, meaning they can spread to distant sites through the bloodstream or lymphatic system.

The growth of a tumor is driven by genetic mutations that disrupt the normal cell cycle regulation. These mutations can lead to cells that divide excessively and fail to undergo programmed cell death (apoptosis). As a tumor grows, it requires a blood supply to provide nutrients and oxygen. This process, known as angiogenesis, involves the formation of new blood vessels that feed the tumor. The rate of tumorengroei can vary significantly depending on the type of tumor, its location, and the individual's overall health. Factors such as genetic predisposition, exposure to carcinogens, and certain viral infections can increase the risk of developing tumors. Understanding the mechanisms of tumorengroei is crucial for developing effective diagnostic and therapeutic strategies.
