Question :Why a malignant tumour considered to be more damaging than a benign tumour? Explain.

The correct answer is -A malignant tumor is considered more damaging than a benign tumor because it has the ability to spread to other parts of the body (metastasize) and invade neighboring tissues. This makes it more difficult to treat and potentially life-threatening.

Malignant tumors are composed of cancerous cells that have the ability to grow uncontrollably and invade surrounding tissues. These cells can break away from the original tumor and travel to other parts of the body through the bloodstream or lymphatic system, forming new tumors in other organs. This process is called metastasis and can lead to serious complications and even death.

In contrast, a benign tumor is composed of non-cancerous cells and does not have the ability to invade surrounding tissues or spread to other parts of the body. Although benign tumors can still cause problems by growing in size and pressing on nearby tissues or organs, they are generally less harmful than malignant tumors.

Therefore, the ability of malignant tumors to metastasize and invade neighboring tissues is what makes them more damaging than benign tumors.
