Detailed explanation-1: -Benign tumors, while sometimes painful and potentially dangerous, don’t pose the same threat as malignant tumors. While benign tumors generally don’t invade and spread, malignant cells are more likely to metastasize, or travel to other areas of the body. They also grow faster.

Detailed explanation-2: -A malignant tumor has irregular borders and grows faster than a benign tumor. A malignant tumor can also spread to other parts of your body. A benign tumor can become quite large, but it will not invade nearby tissue or spread to other parts of your body.

Detailed explanation-3: -Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Detailed explanation-4: -A malignant tumor, however, is capable of both invading surrounding normal tissue and spreading throughout the body via the circulatory or lymphatic systems (metastasis). Only malignant tumors are properly referred to as cancers, and it is their ability to invade and metastasize that makes cancer so dangerous.

Detailed explanation-5: -Malignant tumours are made up of cancer cells. They: usually grow faster than benign tumours. spread into surrounding tissues and cause damage.
