This process can occur in virtually any tissue or organ and is a hallmark of cancer. Tumors can be benign or malignant. Benign tumors are localized and do not invade surrounding tissues or spread to other parts of the body. Malignant tumors, on the other hand, are cancerous. They have the ability to invade local tissues and can metastasize, meaning they spread through the bloodstream or lymphatic system to form secondary tumors in distant organs.
The growth of a tumor is driven by genetic mutations that disrupt normal cell cycle regulation. These
The process of tumörväxt involves several stages, including initiation, promotion, and progression. Initiation involves the initial
