## Step 1<br />Malignant tumors are a type of cancer that can invade nearby tissues and spread to other parts of the body through the blood and lymph systems. This process is known as metastasis.<br /><br />## Step 2<br />The statement "They contain cells that stay clustered together" is not specific to malignant tumors. Both benign and malignant tumors can have cells that cluster together.<br /><br />## Step 3<br />The statement "They can cause tumors in other parts of the body" is true for malignant tumors. This is because malignant tumors can metastasize, or spread, to other parts of the body.<br /><br />## Step 4<br />The statement "They are easily removed through surgery" is not always true. While some malignant tumors can be removed through surgery, others may have spread too much or be in locations that make removal difficult or impossible.<br /><br />## Step 5<br />The statement "They do not require treatment" is false. Malignant tumors often require treatment, which can include surgery, radiation, chemotherapy, or a combination of these methods.
