How Does Cancer Spread?
Cancer is a disease that can occur in nearly any part of the body. It happens when abnormal cells divide uncontrollably, form a tumor and destroy nearby body tissue. The most common type of cancer in women and men are breast cancer and prostate cancer, respectively.
In the early stages of cancer, abnormal cells begin to grow and divide rapidly in a certain part of the body. This is known as cancer growth or carcinoma in situ. As the disease progresses, cancer will eventually form a tumor (growth), which may contain millions of abnormal cells. Cancer spreads when cells from the original tumor break away and enter the bloodstream or lymph system. From there they are carried to other parts of the body.
How does cancer spread?
Cancer cells need oxygen and nutrients to grow and spread. As a tumor grows, its center gets further away from the blood vessels that carry their much needed oxygen and nutrients. In order to survive, cancer cells send out signals known as angiogenic factors, which encourage new blood vessels to grow into and nourish the tumor.
In order for cancer to metastasize (spread) into other organs, it has to go through the following phases successfully:
- Abnormal cells need to break away from the original tumor and enter the bloodstream or lymph system.
- Once inside the bloodstream or lymph system, these cells need to attach themselves to the wall of a blood or lymph vessel and move through it into a new organ.
- During each step of metastatic growth, the cells need to avoid attacks from the bodyb s immune system, so it can grow and thrive in its new location.
