5. Increased vascularity
Increased vascularity over the bone tumor with pulsations indicates that the tumor is growing rapidly and is suggestive of bone cancer, especially when accompanied by other symptoms in this list.
This happens because the tumor is growing in such a way that it requires an increased supply of blood to sustain its growth. This increase in blood supply is facilitated by the formation of additional blood vessels, which provide the tumor with the necessary nutrients. As the tumor grows, it begins to pulsate due to increased blood flow.
The pulsation indicates that the tumor is active and can be felt if the cancer is close to the skin surface. Sometimes, it can also be heard as a faint thumping sound. Knowing the presence of increased vascularity over the bone tumor with pulsations is important in diagnosing and treating bone cancer in its early stages.
