What is a tumor?
A tumor is an abnormal mass of tissue that forms when cells reproduce uncontrollably. These cells don't follow the normal process of programmed cell death and continue dividing, leading to a lump or growth. Tumors can occur anywhere in the body and affect various tissues.
What are the main features of a tumor?
- Cell Growth: Uncontrolled and rapid cell division is the hallmark of a tumor.
- Types: Tumors can be benign (noncancerous) or malignant (cancerous). Benign tumors typically grow slowly and stay confined to their location, while malignant tumors can invade surrounding tissues and spread (metastasize) to other parts of the body.
- Symptoms: Symptoms vary depending on the tumor's location and size. They may include pain, swelling, changes in bowel or urinary habits, or unexplained weight loss.
Why is a tumor important?
- Early Detection: Understanding how tumors develop and behave allows for better diagnostic tools to detect them
