Is a tumor sensitive to the touch?

The answer is yes.

Tumors are often described as being firm, hard, or nodular. This is because they are typically composed of cells that are packed tightly together and have a lot of connective tissue. When you touch a tumor, you are feeling the pressure of these cells and the connective tissue. In some cases, tumors can be tender or painful to the touch. This is because they can put pressure on nerves or other tissues in the body.
