What does invasive cancer indicate about cancer cells?

Invasive cancer indicates that the cancer cells have the potential to spread beyond their original tissue or organ. This characteristic signifies that the cells have acquired the ability to break through surrounding tissues and infiltrate adjacent areas, which can lead to metastasis, or the spreading of cancer to distant sites in the body. The invasive nature of these cancer cells is a key factor in determining the aggressiveness of the cancer and influences treatment decisions.

While cancer cells that remain confined to their original location might still cause localized issues, invasive cancer poses a greater risk due to its potential to spread, making it more difficult to treat and control. It also suggests a more advanced stage of the disease, often requiring more aggressive treatment approaches.
