Tumors are classified into two types: benign and malignant.
- Benign Tumors: Benign tumors are non-cancerous growths that remain localized to their site of origin and do not invade surrounding tissues or spread to other parts of the body. These tumors are typically well-defined and encapsulated, and their growth is slow and controlled. They do not possess the ability to metastasize. Although benign tumors can cause health issues depending on their size and location, they are generally not life-threatening. Examples of benign tumors include certain types of moles, fibroids, and lipomas.
- Malignant Tumors: Malignant tumors, also known as cancerous tumors, are characterized by uncontrolled growth and the ability to invade nearby tissues and spread to distant sites in the body. These tumors can infiltrate surrounding tissues, damaging and destroying healthy cells and structures. Malignant tumors have the potential to metastasize, which means that cancer cells can break away from the primary tumor, enter the bloodstream or lymphatic system, and establish secondary tumors in other parts of the body. Metastasis is a major concern in cancer, as it can lead to the spread of cancer to vital organs and tissues, making treatment more challenging. Examples of malignant tumors include carcinomas, sarcomas, and leukemia.
Therefore, the correct answer is (a) Benign tumor, as it is the type of tumor that remains confined to its original location and does not spread to other parts of the body. |
