Cancer is a complex group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. Normally, cells grow, divide, and die in an orderly manner. However, cancer disrupts this process, causing cells to divide and grow uncontrollably, forming a mass of tissue called a tumor. There are two main types of tumors: Benign tumors: These tumors are non-cancerous and do not spread to other parts of the body. They can often be removed and are less life-threatening than malignant tumors. Malignant tumors: These tumors are cancerous and have the ability to invade nearby tissues and spread to other parts of the body through a process called metastasis. Metastasis is a key characteristic of cancer and can make it more challenging to treat. Cancer can occur in almost any part of the body and can affect various organs and systems. It arises from genetic mutations or changes that alter the normal regulation of cell growth and division. These mutations can be inherited...
