Multiple Choice

What are the main differences between benign and malignant tumors?

Benign tumors can invade other tissues, while malignant tumors cannot.

Benign tumors are non-cancerous and do not spread, while malignant tumors are cancerous and can invade other tissues.

Benign tumors are always larger than malignant tumors.

Malignant tumors are non-cancerous and remain localized, while benign tumors spread to other parts of the body.

Verified step by step guidance

Begin by defining what a tumor is: a tumor is an abnormal growth of cells that can be benign or malignant.

Explain that benign tumors are non-cancerous, meaning they do not invade nearby tissues or spread to other parts of the body. They are usually encapsulated and grow slowly.

Describe malignant tumors as cancerous, which means they have the ability to invade surrounding tissues and spread to distant parts of the body through a process called metastasis.

Clarify that benign tumors typically remain localized and can often be removed surgically with little risk of recurrence, whereas malignant tumors may require more aggressive treatments such as chemotherapy, radiation, or surgery due to their invasive nature.

Summarize the key differences: benign tumors are non-cancerous and localized, while malignant tumors are cancerous and can invade and spread to other tissues.
