Vähkkasvajate
Vähkkasvajate, also known as malignant neoplasms or cancers, are a group of diseases characterized by uncontrolled cell growth and the ability to invade other tissues. In a normal body, cells grow, divide, and die in a regulated manner. This process ensures that new cells replace old ones, maintaining the body's structure and function. However, in cancer, this regulation breaks down. Cells begin to divide abnormally and do not die when they should, leading to the formation of a mass called a tumor.
These tumors can be either benign or malignant. Benign tumors are generally not life-threatening; they grow
The development of cancer is a complex process that can be influenced by a variety of factors.
