Answer:
- Cancers grow very large because the cells in the tumor divide uncontrollably and continue to accumulate.
- The growth of cancer is aided by blood vessels that supply the tumor with nutrients and oxygen, which allows it to grow and invade surrounding tissue.
- Cancer cells also often have mutations that allow them to evade the body's immune system, which would normally be able to identify and destroy abnormal cells.
- Cancers can also grow undetected for a long time, especially if they are located in areas that are not easily accessible or do not cause symptoms.
- As the tumor grows larger, it can also begin to interfere with the functioning of nearby organs and tissues, which can further exacerbate the growth of the tumor.
- If left untreated, cancers can continue to grow and spread to other parts of the body through a process called metastasis.
- Metastatic cancer can be much harder to treat than localized cancer, which is why it is important to catch and treat cancer early.
- Therefore, regular cancer screenings and early intervention are important in order to detect and treat cancer before it has a chance to grow too large.
